  Review: DCM TimeWindow 1 Speaker
This review covers the orignal DCM Time Windows. Not the subsequent versions.

I remember the first time I heard these. Their unique shape and sound where unlike anything I had heard before. Here was a speaker that really delivered the promise. It was driven by a PS Audio Amp and PS Audio LCC PreAmp. At the time I had the Large Advents,and while those speakers were very good indeed, the Time Windows were clearly superior. The music just seemed to come alive in a way that's hard to describe. There was just a seamless transparency to them. Not overly bright or accentuated on the bass. The balance was right on. It didn't really matter what the program material was, the Time Windows clearly and with authority brought the music to life. If they had any real weakness is for some peoples taste the bass may have been on the light side. But for my taste it was as it should be. The orginals used Philips drivers using a transmission line and the cabinet construction contributed to the overall sound. In the late 70s these were not cheap at about $800.00 but were indeed worth the price of admission. I was finally able to acquire a pair of these and have them to this day. Few things one purchases in life have enduring value and the Time Windows truly are in that category. Of all the reviews I have read on these speakers not one reviewer has clearly defined the sonics of this fabulous speaker. Use all of the adjectives you want and one will still come up short in the description. Best way to describe them, if you love music and have better than average components connected to them, the Time Windows will deliver the music with a verve that will astound you.

Now these speakers are some 20 years or more in age and continue to deliver the music. And that's what this hobby is all about. DCM no longer produces the Time Windows,having opted for the HT route. This is a true shame as these speakers deserve continued production. Timeless design is just that.

Specifications:

  • Dimensions:36"H x 14 3/4"W x 11 3/4"D
  • Weight:32 Pounds
  • Power Requirements:10 Watts Minimum per channel 89 dB/watt at one meter;200 Watts Maximum
  • Impedance:5 Ohms minimum/6-8 Ohms nominal
  • Frequency Range:25Hz to 18 kHz
  • Dispersion:180 degrees horizontal/60 degrees vertical.

    Specifications do not tell the whole story,listening does. The Time Windows due to their configuration can be literally tuned to any room. That is due to their shape. This was a brilliantly executed design that has remained faithful all these years.

    Review: DCM TimeWindow 1 Speaker
    Nice to see some conversation about these wonderful speakers. I bought a pair in '78 and they have been in regular use ever since.

    After living with these for so long, and powering them with a variety of mid-fi solid-state amps, I can say that *if* there is a lack of bass response, it exists primarily because this speaker accurately plays what's handed to it.

    Case in point: For years, I thought the speakers were bass-shy. Then about 6 years ago I switched to tube amps and was *completely* astonished at the bass coming from these speakers...which were so widely believed to be deficient in that area.

    OK, so they're rated only down to 30db and only 89db efficiency, but do we really expect better from an $800 pair built in '78?

    The moral: switch to a tube amp--even a vintage, unmodded one--and you'll banish thoughts of getting rid of your Time Windows.

    I had a pair of these before buying Vandersteen 2CE's. One time I brought them to a party held in a gym, using a Luxman integrated amp and Cd player. They literally filled the room! Other speakers may be more accurate and/or have deeper bass or more extended highs, but the Time Windows sounded ALIVE! I may get another pair on Ebay soon.

    Review: DCM TimeWindow 1 Speaker
    Ah, the Time Windows. I still own and use my original pair of Time Windows purchased back in the late '70's. It's very interesting that nobody who has responded to this thread has even attempted to characterized the sonic attributes of these great old speakers. Frequency response be damned, the Time Windows defy specs. Their presentation is just plain musical. They are vastly more than the sum of their parts. I had the prvilige of selling the Time Windows in an audio store for a few of years and can attest that no one ever expected that kind of sound to come out of a medium size tower with only two 6 1/2 woofers and two Phillips dome tweeters. How did they do it? Magic I guess...

    Review: DCM TimeWindow 1 Speaker
    I bought mine in 1981. Still have them and have just now replaced the grill "foam" with fabric. My eye opener was when I auditioned them before buying. The system was made up of a PS Audio amp and Preamp tied to a Denon turntable sporting a Grace F9E Ruby cartridge. Violins and female sopranoes shine on this setup. I didn't hear anything about it I didn't like. Loving live music as I do, it was the nearest thing to bringing that home I could find. There were times when I thought that adding a sub would be the thing to do but, invariably, when the speakers were moved to a room more in keeping with their size or moved within the room to find just the right spot, that problem went away.They sounded so transparent to me, as in there was nothing between me and the musicians. Is this subjective enough?

    I still enjoy them. They still rock.

    I bought my TW1s in 1982 and they were in "main" service until September 2003. Our cats did in the foam socks, so I'm going to try grille cloth on them. The replacement "mains" are Totem Forests. The TW1s were powered by a Hafler 220 throughout their years of use. The Hafler is on the bench right now, most of the way through a "hyper" mod involving Musical Concepts driver boards and a dual-mono power supply (96,000µF, IXYS FRED rectifier bridges, dual-secondary toroidal power transformer). It will be interesting to see how they sound with the hyper-Hafler. They were always very well balanced, neutral, "musical" speakers, though not as pinpoint precise as the better ones available today at equivalent (adjusted for inflation) cost. Has anyone explored modernizing the drivers?

    Review: DCM TimeWindow 1 Speaker
    I am very happy for there are still so many people love the DCM speakers. I got a pair of Timewindow 3 recently. They are in very good condition. However, I found most people talked about TW 1a or TW 7, but not TW 3. How do you think its sound? Can it beat the normal $1,000 speakers in the current market?

    I do not have much experience, and my amplifier is a small
    Adcom 535(60W*2). According to my hearing, the bass is far from 24hz, which is publicized by DCM. Although the
    89db-sensitivity is not low, I think a more powerful amplifier will make them better. Do you have any suggestions about the amplifier?

    Thanks and enjoy your DCM speakers.

    I owned a pair of 1A models from 1981 until a home burgulary in 1991. I would love to get my hands on another set so I keep checking ebay where several pairs have been sold.

    Regarding the sound:

    After I was married in 1988, my wife made a comment about 'my' speakers. Her comment was: "the singers sound real".

    Is there any more that needs to be said?

    Review: DCM TimeWindow 3 Speaker
    I purchased a pair of Time Window 3's in about '82. My cousin owned an audio store in Minneapolis. He always had someone in their trying to sell him their top end speakers. When I was ready to buy I said what's the best you have and he played the DCM's for me. Wow! So crisp and clean. Yes sounds amazing on them. I also have TF-350's to round out the sound.

    Unfortunately, my receiver is a Luxman from the same vintage and it only has 35 watts total. I think it distorts out before the Time Windows even get warmed up. I don't think I've ever heard the best they can do since that day in the store. I need to upgrade my receiver, but I'll never get rid of my speakers. The 4 combined will make for an awesome home theater (now I just have to buy a TV!).

    You can contact DCM directly, they're still around. If not, you can have someone sew a sheet of the materail from Parts Express to size, creating a tube. The tops and bottom wood comes off somehow by twisting, then slide the fabric over the speakers.

    I spent three decades in the audio business and I considered the Time Windows to be a true classic. I own a pair, I use them in my woodworking shop. The grills are long gone, and they are chipped and scratched, but they still deliver. I use an Onkyo A-9 integrated amp and an Onkyo T-10 tuner with them. I also have an old Yamaha cassette deck and an onkyo CD. I change cd players frewuently because of the dust and all.

    Review: DCM TimeWindow 1 Speaker
    In 1978 I bought my first pair of TW1. I didn't know a lot about good sounding speakers, but I knew that I liked these. I wound up selling them in 1986, to a good friend who begged me for them. I then bought the TW1a, I was told they had a little more bass, which they did. In 2002 I wanted to upgrade my system complete, I spent a lot of time and research looking for a speaker to WOW me, like the TW always did. I bought a set of Jamo E8 towers. I was not WOWed. I sold them for Jamo concert 11s. These speakers wowed me......but at what cost. I still have my TW1a's in my family room, hooked up to a small 110 amp Pioneer. They still sound fantastic. I will never get rid of these classic, Great sounding speakers. Thank you DCM.

    Review: DCM TimeWindow 1 Speaker
    A friend of mine has the Aerial 7 and they are fabulous. Whereas the Time Windows work very well with any quality amp,the Aerials are very unforgiving with less than very good amps. They need at least a mosfet output amp and at least 75 watts per channel to really perform. Threshold,Forte,Classe,Bryston,Levinson and other amps in this league is what you will need to really bring the Aerials alive. At the time I heard them they were being driven with a Classe 70 amp. He now has them connected to a Bryston 4 SST amp. I bought the Classe 70 from him for my second system,which is now listed on Audiogon.

    While the Aerials are very good and would love to have them.I still find the Time Windows just magical for me.

    Timewindow 1A solid-state amplifier?
    Any recommendations for ss amplification to drive a pair of Timewindow 1As? Love them with my Jolida tube amp, but constant adjustments to minimize hum, replace bad tubes, and now a downed capacitor got me scrambling back to solid state.

    The hitch is that I've got a pretty tight budget for this system, so I've been looking at used Hafler, NAD, GAS, Accuphase, Tandberg, and McCormack stuff. Love these speakers for all the reasons everyone's been pointing out, but what's the most synergistic solid state amplification? Anyone experience particularly good/bad amplication matches? Sources include a Rega turntable and CAL CD player. Thanks.

    I was lucky enough to recieve a pair of these speakers from my dad since he got new speakers that took up less space but have nowhere near the sounds quality. The best story I remember about these speakers is my dad telling me that when he was stationed in Hawaii, he had these speakers set up outside at a party that was next to a golf course, and the end of one of the songs ended in a rain storm, and the sound was so true to life that it sent the golfers on the nearest hole to the clubhouse. I'm only 18 but have grown up hearing nothing but quality speakers and these have the best sound I've ever heard. The bass which was appearently a problem to some people is heard with great detail, but it's not just pounding or felt. Nothing could ever replace these.

    I also have a pair of time windows and also a pair of Dalquest DQ10. I love them both, as I did back inthe early 80's when i bought them. We always liked to party to the Time Windows, as they seemed to have more punch.

    The sad part about it that direct replacement drivers are not available. My pair really needs tweeters but i don't think i have any options other then replacements. Of the folks I have talked to about this, they all said that DCM used fairly cheap drivers.

    any iindeas / info here? My TW dont sound anything like they use to :( Whwn I called DCM, they seemed somewhat disinterested in the speakers.

    Review: DCM TimeWindow 1 Speaker
    The original TWs had hexagonal woofers and 1" dome tweeters, both by Philips, and both excellent. The tweeters only went to 18KHz, but they sounded nice.

    I recently emailed DCM about replacement drivers and grill cloth. They referred me to Parts Express for tweeters and McMaster-Carr for foam grill cloth. No info on woofers.

    You might email DCM with your question. They were much more helpful this time than when I asked the same questions a couple of years ago.

    Review: DCM TimeWindow 1 Speaker
    After reading these posts, I felt motivated to re-connect my 1982 vintage Time Windows. They have functioned as sound reinforcements in the corners for many years since I purchased Dynaudio Audience 42s. I was very pleasantly surprised by the overall performance of the Time Windows after having been exposed to the Dynaudio sound. The Time Windows do indeed sound remarkable, much better than I ever anticipated. I am driving them with a Sumo Nine Class A amplifier, purchased also in 1982 when I bought the DCMs. The combination of Sumo and the Time Windows is exceptional. The Sumo Nine is an underrated Class A amp designed by James Bongiorno. He insists he has never had an output transistor fail in a Sumo Nine, and I can vouch for that, at least with my own amp. With an ADCOM preamp/tuner feeding the signals, this is a very musical lineup. The sense of spaciousness from the Time Windows is refreshing, and never feels like an exaggeration. I am not sure right now whether I prefer the overall performance of the Time Windows or the Dynaudios. It is nice to have both in the house.

    I have TW IA's...DCM was bought out! And drivers are nolonger available, atleast not the same drivers used to make these speakers breath...Anyone have any suggestions?
    wobbie64@netscape.net 02-21-05


    Review: DCM TimeWindow 1 Speaker
    Just curious. Since the original Time Window used Philips drivers, is it possible to inquire directly through Philips as to availability of the raw speaker elements?
    I am not certain of the viability, since Philips is such a huge conglomerate.. But maybe someone knows a way to access someone there who might know.

    I am enjoying my own Time Windows more and more with each passing day. I have been using an Adcom preamp/tuner for a couple of years now. It has two sets of preamp out connections, one of which bypasses the tone controls. I mistakenly thought I had been using this link, but only within the last coup[le off days did I learn that I had been mistaken. I made the switch to the link without tone controls. What an amazing difference. I have never heard these speakers perform to their real capabilities before. This is truly liike acquiring a whole new system without spending one penny. The resolution across the full audible spectrum is much better, far beyond anything I have heard in my home before. My Dynaudio Audience 42s will be sitting idle for the foreseeable future. And forget my other speakers, Tannoy Mercury M2s. They cannot possibly compete with the sound I am enjoying right now.

    Thejapelvis 02-22-05


    Review: DCM TimeWindow 1 Speaker
    I have been even more impressed with the performance of these speakers since I noticed that my preamp out connections were not what I originally had in mind. I was under the false impression that I had bypassed the tone controls on my Adcom preamp. This was not the case. So I made the switch to the preamp out connections that totally bypass the tone controls. The improvement was immediately noticeable. Every part of the frequency spectrum sounds better, smoother and more resolute. Voices are more completely defined. Every vowel and consonant is clearly enunciated. Perdussion sounds much better across the board. And the highs are sweeter. This is quite a pleasant surp[rise. I am now more than ever seeing the DCM Time Windows as "The Poor Man's Quads."
    Thejapelvis 02-27-05


    Review: DCM TimeWindow 1 Speaker
    Thejapelvis - Try using a Class A output preamp along with your Sumo Nine Class A amp. This should really open up the Time Windows another level or two. While the Adcom tuner/preamp is a fine unit, it may be holding back the Sumo amp. Just a thought on my part. Have powered the Time Windows with a Forte Class A Amp and Forte Class A preamp and really found this to bring the Time Windows to a very high level indeed. Enjoy those Classic Time Windows, they are special indeed.

    Thanks for the tip, Ferrari. What might be a good deal on the Forte Class A preamp you recommend? I am not familiar. Sounds like great advice.
    Thejapelvis 02-27-05


    Review: DCM TimeWindow 1 Speaker
    Ferrari, I have just seen the review of the Forte Class A preamp on this site. This is one sweet unit, no doubt. I have something to aim for. This is exactly the type of preamp I always wish I had in my system. It would provide the real crowning touch. I wil keep my eyes and ears open for this, should it come up inh the used market. Not exactly the kind of piece that you could get from the Salvation Army thrift shoip, as so many audio enthusiasts like to brag about. The Forte would likely make my Dynaudio Audience 42 sound that much better as well. Thank you for the heads up.

    Review: DCM TimeWindow 1 Speaker
    Just put spikes under my DCM 1As, and though this may have been an obvious add-on it's really tightened up the bass and opened up the sound. (I had them just resting on carpet before.) I think someone way back in the thread asked about reconing - I've been using my DCMs for over 20 years now, and they still sound as good as the day I got 'em. But anyone know whether these things need periodic maintainence - foam rot or cracking or whatever?

    Review: DCM TimeWindow 1 Speaker
    The DCM Time Windows Original and 1a used Philips drivers and they have butyl surrounds for the drivers, not foam. I do not see any need to service those drivers, unless of course one over powers them and frys the voice coils. Other than that sit back,relax and enjoy.

    DCM stands for "Dreps Crone Maze"

    I have a set of TW1a's, TW3's and the "BIG Daddy" TimeWindow Seven's. If your are looking for a center or surround speaker, the CX17 are a perfect voice match for the TimeFrame and the TW3's & TW7's.

    These speakers are built to last.

    Amen to the last post. I was earlier thinking I might want to sell my Time Windows. But after spending the month of February listening to them again, I no longer feel like selling. It would be hard to find an equivalent speaker on today's market, without spending an obscene amount of money. The real value of the Time Window proves itself over and over. I am listening to my Dynaudio Audience 42 this month. But I will put the Time Windows back into the system during April. I have decided this is a nice arrangement.

    Hello all
    Was sold on the sound of the time windows the first time I heard them in 1980. Bought, used, loved and abused them until their untimate demise a couple of years back. At about that time, in search of replacements for my dry rotted grills, I passed up the then factory rebuild offer of $300.00 (including new drivers and crossovers!). I am now in dire need of either replacements, or a skilled rebuild. I hope someone here understands my pain and can point me in the right directions.

    Like previously stated, McMaster is the source for the grill/sock replacement fabric. DCM cust svc even game me the part#, which I don't have handy right now.

    Way back when, I had owned Time Window's, TW3's, and the 1A's. All excellent choices, powered by Onkyo M-504 amp/P-304 preamp combo. All of the vintage DCM speakers are very musical, exhibit nice resolution, nice soundstaging from L to R/top to bottom/front to rear, and play the low frequencies much better than their size would indicate.

    After a three-year hiatus from the audio "habit", I'm back. Luckily, I still have my faithful Time Windows. They do need some TLC. The drivers themselves sound as wonderful as when new, especially driven by my Cary SLI-80. The top and bottom caps need refinishing/replacement...has anyone attempted or accomplished this task?

    I'll be attempting that and more.
    My grills were dead long ago, but thankfuly not the sound. My real need now is (1) original woofer(cone literally dangling from internal lead) and (1) tweeter (somehow MIA). With the help of this site, I did reach help with the grills, a potential driver rebuild, and I think an original tweeter. Seems my woofer problem is inoperable. Now faced with replacing one woofer with imposter. Any help ?

    Mark,

    In the floorstanding speaker section of eBay, I noticed a guy that had a pair of replacement tweeters for DCM speakers. I didn't look to see what else he may have on hand. You might try a search there? Seems like it might make some sense to replace both tweeters for the sake of symmetry. The original tweeters were only good to 18kHz, with newer drivers probably out to 20kHz or so.

    Has anyone tried removing the top and base plates? I don't want to do more harm than good while attempting to do so.

    I ordered a set of spikes, and I'll be installing those this week. I'll post feedback on the results sometime soon.

    Just a quick update...intalled the floor spikes in the bottom plate of the TW's. As I had hoped, this tightened the bass and midbass up quite nicely. It improved the overall soundstage a bit also. This upgrade is a very nice "bang for the buck".

    Not dumb questions at all.

    I bought mine at www.oregondv.com. I'm sure there are other sources, but I found them quickly via a Yahoo search.

    If I recall correctly, the 7's are quite a bit larger than the original TW's. However, one is limited by the thickness of the bottom plate of the speaker. I purchased the 1/4" spikes, as the depth of the bottom plate is somewhat limited on the TW's.

    The guy who originally sold me my pair of Time Windows back in 1982 still has a pair of the legendary Rogers LS3/5A speakers. I think for the most part the two speakers share the same basic tonal balance, although the extreme spaciousness of the Time Window is probably something that sets this speaker apart from the Rogers. Also, the LS3/5A does not have the same bass characteristic as the Time Window. But it seems to me both speakers roll off the top end very quickly above 18,000 Hz, and it is probably this quality that invites comparison. One thing is certain. Both speakers seem to have their dedicated following, and for good reason. They remain competitive today with even the best designs. I never intend to part with my Time Windows. It would cost too much to find a better speaker.

    Yes, Ferrari, the LS3/5A is a 16 ohm load. Personally I think they are more trouble than they are worth. They have a real dedicated following, which tells you the speaker is definitely solid in most key areas of performance. But I think the Time Window is far easier to live with in real world terms. They have survived in my house for 23 years.

    Hello, I had to chime in this blog as I could not help myself. I have been a dedicated fan of DCM speakers since I heard them for the first time @ Circuit City in 1992. I fell in love with their lineup (Monitors) and worked my up to the (Time Frames) and eventually upgraded to the Time Windows (3 series).

    Today, I own the elusive Time Window 7's which I was lucky enough to pick up on Ebay a couple years ago.

    I can honestly say, I will never part my Time Windows because they are best sounding speaker which I believe will stand the test of time!

    Here, let me see if I can decribe accurately how these speakers sound althought I recommmend you audition these in person...

    The tonal balance is very accurate, vocal imaging crisp and detailed. The bass is deep (yet accurate); the TW7's creates bass to drops all the way down to the threshold (lower limits) of human hearing (20hz).

    FYI: when sound is created at 20hz, it's more of a vibration you can feel (like when you go to a 'live' performance.

    Just be sure to matchup your speakers to a nice amp to enjoy
    ultra low sonic distortion in highs, midrange and lows.

    I am currently running a 160watts @ 4ohms using a Denon 2 channel ultra high current amp. (PMV2000IVR)

    and that's all I have to say about the DCM Time Windows.

    Btw, I've at one time all of the following DCM speakers below:

    CX-17's, CX-27's, Time Frame 600, Time Frame 1000, Time Window 1A, Time Window 3's and currently I possess the Time Window 7's.

    I bought a pair of Time Windows at a garage sale for $10. $10 DOLLARS! The kid two seconds behind me begged me for them for his XBOX gaming. Too bad, I got there first. Their grill cloth was long gone and the wood on one was a little rough. I resealed the enclosures, which were in great shape, with black silicon seal in a couple places to be sure they were still air tight. At the supermarket I bought some of the shelving liner you put in your cupbords under your dishes and glasses, its an open-meshed rubberized foam of some kind. Painted the wood tops and bottoms flat black, wrapped them in black shelving liner, and they looked and sounded fabulous, even powered with my little vintage Pioneer SX-3500 with 6 spectrum booster/equalizer. Unfortunately I lost them in a flood. I almost cried. I have since purchased two more pairs on eBay recently in "like new" and "excellent" condition, and continue to go forth and rock. Sorry if you lost the bids!

    Well, this is a fun site to run across; lots of other Time Window freaks. I bought my first set of Time Windows in 1981 as a divorce present for myself. My marriage to them has now lasted nearly three times as long as the one to my firs wife. I have played them with lots of different electronics and listened to a lot of other speakers in the ensuing years. Other speakers make me nervous. A couple of years ago I purchased a pair of Time Window 3s. Although, I also love these speakers, I think that when George sends me to Guantanamo I will take the original Time Windows with me.

    Home theater and time windows

    Does anyone know if the old time windows can be used or even if it is a good idea to use them with
    the modern 5.1 home theater a/v receivers .

    Review: DCM TimeWindow 1 Speaker
    My Time Windows are still going strong after 24 years of use and abuse. I'm currently using them in my second system, a 2-channel "home theater" system run by the Carver Receiver which is just about as old. They still sound great.

    I remember the first time I heard them was in a stereo store in Columbia, MO and they just lit the room up. Everyone wandered over to them to hear these new, odd shaped speakers. I still like the concept of the prismatic face with dual sets of drivers. The horizontal dispersion easily fills up a room with sound. This works well for movies also, since I don't have a center channel, they fill the space in front of the TV quite well with dialogue. I agree with others above, they were a little soft at the extremes but for the rest of the bandwidth, they were fairly linear and very transparent sounding for the time. I've occasionally thought of selling them but can never get myself to part with them. They were my first real "high end" speaker and they've become part of the family.

    From an employee, what DCM really stands for
    Ok guys, I actually work for DCM - or more to the point, for Mitek - the parent company of DCM.

    Originally, DCM stood for De-Criminalize Marijuana. Yes, really. However, for the sake of political correctness we now state "Distinctively Clear Music"

    By the way, the new TFE200's are phenomenal. If you enjoy the old sound of DCM, audition a pair of the new TFE's - it will be worth your time. They're not junk like the FT series (which is GOING AWAY! yay!!!)

    Review: DCM TimeWindow 1 Speaker
    I have now been listening again to the Time Window for a five day period, after switching from the Dynaudio Audience 42. One thing for sure, the Time Window is capable of some very nice bass output, which sets it apart immediately from the Audience 42. The Dynaudio is better oin the extreme top end, which creates a different spatial perspective than the Time Window. Both speakers seem valid to me. Hard to say one or the other is definitely better. But the Time Window does create a staggeringly good soundstage, with very definite placement of performers. This is without doubt a great speaker design, one easy to live with. One can do far worse.

    Review: DCM TimeWindow 1 Speaker
    Cwheh,
    The TimeWindows do very well in a 5.1 set up. The apex of the speaker should point straight forward for the mains. If used for surrounds you need to point them at each other from the side walls behind the listening area. Try to find a DCM CX-17 for center channel.

    Apanthropy,
    It was also said that DCM stood for "Drug Capital of Michigan" because they were made in Ann Arbor. Actualy DCM stands for "Dreps Crone Maze". I got that directly from Steve Eberbach.

    There's a set of TimeWidow Three's (much more refined then the original or 1a) on Ebay right now, those are the ones to get, Unless you can find Steve's signature series the TimeWindow Sevens.

    I bought a pair in the 70's and used them happily into the 21st century. My son now has them in his university dorm, much to the delight of his floor mates. I solved the grill cloth replacement problem by glueing a thin dense foam all over the cabinet, cutting out holes for the speakers and ports, and then using fabric glue to put a conventional grill cloth fabric over top. It worked flawlessly and looks as good as the original.

    I'd like to connect a pair of Time Windows to my Onkyo AV Receiver as speaker system "B" for my second room. Or even as part of speaker system "A" for the main room. However, Onkyo requires a minimum impedence of 8 ohms or damage to the AV Receiver will occur. Will my AV Receiver be damaged if I connect the Time Windows to it? The impedence rating for the Time Windows is not disclosed on the name plate and I read here at the start of thread that the Time Windows impedence is between 5 and 8 ohms. Thank you, anxious to try.
    pullfinger@usa.net 12-18-05


    Review: DCM TimeWindow 1 Speaker
    Nominal impedance for the Time Windows is 6 ohms. Not really knowing how much muscle the Onkyo really has,makes me think that one should proceed with caution.Because the ohm load will drop based upon program material. A lot of the newer AV gear just pukes at the lower impedances. Trying to combine a music system with home theater system usually doesn't work very well. Unless of course one spends a lot to do this such as the products from Lexicon and some others that have high current amps. If possible set up a Home Theater system and a Two Channel Audio system in separate rooms, if that is an option. If not then one has to make the choice HT or Music.

    Review: DCM TimeWindow 1 Speaker
    Just discovered this forum. I've been a TW 1 owner since 1976. When the HT bug bit, I wasn't ready to put a lotta bucks into new speakers and gear, so (reluctantly) used the Time Windows as the main fronts with an Infinity (can't recall the model) center and in-ceiling rears. Sounded real good driven by a Sherwood Newcastle R-945 receiver, although the unmatched center and rears detracted from what the TW 1s brought to the game. Recently rebuilt the entire Home Theater with Rotel (1098 controller, 1075 amp, 1060 DVD) components, B&W 603S3s/600LCRs, and dual Velodyne SPL 800 subs . The Home Theater now sounds GREAT, but the point of bringing that up here is to say that that let me put my Time Windows back as my music only stereo system where they started and best belong. They're on Tiptoes and driven through a Crown IC-150 preamp/D-150A amp with a Rotel RCC 1055 CD source, and sound as absolutely wonderful as ever, regardless of the type of music I'm listening to or whether at reduced or high volume levels. IMHO, these are THE premier classic stereo speakers of their era and have yet to be outdone by but a few of the newcomers at any reasonable cost level.

    I owned a pair of the original Time Windows in 1978 or 79. They were awesome. I lived in an apartment so I had to be very careful not to crank them up so I wouldn't get too many complaints. They were on my living room long wall facing a common wall to the next apartment. That neighbor moved out, so one day I put on the Rolling Stone and cranked it up. A short while later there was pounding on my door. A very upset guy told me he was checking out the empty apartment and the common wall was vibrating!

    In the late 70's and early 80's my system included my original Time Windows and a Pioneer SX1250 Receiver. It was great. This past Saturday while cleaning up the store room in my basement I decided to lug the Pioneer up stairs and hook it up to the Time Windows again. Having not been plugged in for at least 16 years, it took the receiver a half hour or so to completely wake up. But, once it did, that combo sounds just as wonderful as ever. It is like two old lovers reuniting in the livingroom. As soon as my back recovers and I can lift the SX1250 again I am going to move it and the speakers permanently into the dining room.

    Review: DCM TimeWindow 1 Speaker
    Remember that Pioneer SX 1250 very well, one of Pioneers best receivers. Good design with external heat sinks. Built like the proverbial tank, that came out during the stereo receiver wars of the late 70s early 80s. Few high power receivers were built and designed correctly, but this one was. This was about as good as it gets in high power receivers. Not quite in the same league as the McIntosh 1700,1900 or 4100 or the Marantz 18 or 19, but those were not high power receivers. All of these were statement receivers from the golden age. Well worth keeping and restoring and updating from time to time.

    Todays receivers can't even remotely come close to these great vintage receivers, that forever changed the design and performance of the stereo receiver into a viable medium.

    Yep to all. I used to lust for an SX 1980. I'm not even sure why except that it was even bigger. But, having listened to them at the time and subsequently, the 1250 sounds every bit as good. I was afraid that after sitting so long it would need some work, like capacitors. But, the left channel was a little thin for awhile but suddenly came alive and the whole unit has now been playing constantly for the past week or so and sounds perfect. I'd forgotten how smoothly all of the controls work and how neat the silky analog tuner works.

    The best I ever got my Time Windows to sound was in a previous house I owned. The dimensions of the rectangular room were in the exact Fibonacci ratio. They were placed three feet from the back wall, which was covered with Sonex, about two and a half feet from the side walls and six feet apart. They stood on Tippy Toes on a cement floor with about 15 pounds of weight on top of each. Listening was from about 8 feet back. My turn table was near the back of the room sitting on 12 cement blocks. In this set up they just disappeared.

    Oh Yeah. Once, when I first got my Time Windows back in 1980 or so, I also built a set of 14" stands forthem because I read a reviewer somewhere or other suggesting that it would "raise" the sound stage. It indeed did just that, making it about equal top to bottom as from side to side. One thing I have never tried is both raising them and spiking them down solidly at the same time. I can only imagine how this would effect things.

    Maybe I'll build a new set of stands. I gave the original ones to a friend with an unruly 2 year old to keep him from kicking the grill foam off of his JBLs.

    This is all great bs. I am interested(since I have the original DCM's) in how to get the best from them. My current situation is about 2 feet from the back walls. My understanding is that 3 feet are proper. Let's get some life into this situation. Are you guys dead out there? Controversy is great(I'm the "When is digital going to get the soul of music guy.)! BTW, I am a horn guy. I bought Ferrari's Classe amp. The Nuforce amp is so superior, it's unbelievable.

    I 1st heard the TimeWindows a few years ago at a friends house. he had timeframes also, and all sorts of other stuff, mostly 50's & 60's era. the windows stood out as special amoung all the huge jbls, and jbl 100's and bozaks and lord knows what else he played for me. he was driving them with macintosh mono blocks and a marantz model 7 pre.
    same friend got me a pair of kef 105.2's which I still love, but when he offered to sell me his timewindows 2 years back I was very very excited. then he sold me his model 7, and hooked me up with an old audionics of oregon ba150 tube amp. the windows sound fantastic with this gear. the kefs present a completely different sound. more refined maybe, amazing highs and detail. but the windows sound like no other speakers, and when the 105.2's just don't have the punch to rock it, the time windows do just that, and then some.

    Yep, those original Time Widows are truly classics. I remember Peter Aczel stating in his review(@1977) that although other speakers could do certain things better, the Time Windows just gave that "breath of life" that those other speakers didn't have. I kept mine for about 10 years, sold them to buy the new(at the time) Vandersteen 2B's and although I thoroughly enjoyed the Vandersteens, I missed from time to time those beloved Time Windows.

    Review: DCM TimeWindow 1 Speaker
    Yes, I also have a response buried waaay back there somewhere over a year or so ago....what a thread! You're review was certainly spot on.

    I still haven't replaced my cat-torn grill material but I intend to.
    I'm still amazed at the performance of these speakers after 27 years. I also had a pair of the TW-7s but foolishly let them go a couple of years ago. They were also great speakers and I wish I'd tried a few simple tweeks on them. For instance, they should have had some acoustic damping material inside to eliminate any trace of standing waves, and the bass port could have been reduced to tighten/quicken the bass a bit.

    Has anyone heard these speakers (originals) stacked...That is, two pair stacked on top of each other either biwired of jumpered? They really did sound great that way; a much bigger and more relaxed presentation. When used that way the upper speakers should be upside down to provide better focus and imaging. A friend managed a high end show in Carmel, CA, at the time and we used to enjoy the hell out of trying such things. Anyone remember Audio Components of Carmel and Keith Yates? Keith is now designing state-of-the-art rooms and theaters in the Sacremento area. (Keithyatesaudio.com)

    Used alone, a single pair benefits from being elevated a bit. I recall someone doing a study and coming up with them sounding best exactly 9 inches above the floor. I took that as gospel and built two stands from solid black walnut slabs exactly 9 inches high and shaped exactly like the TW endplates. They were difficult to fashion (using a chain saw, 5" sanding disk on the end of an electric drill, and a pad sander) but well worth it. The most difficult part was getting the tops and bottoms perfectly parallel. The TWs do sound very good perched on those and it also seems to help to keep a little weight on the speakers to couple the array to the floor. Bronze statues do the trick for me.

    Those speakers still are sounding great in my downstairs system. They are very close to the back wall in this configuration, but for some reason they sound superb that way....plenty of bass! Lack of deep bass was considered this speaker's greatest weakness way back when.

    As I recall from the original DCM owner's manual (which I still have), DCM's recommendation was to keep them a minimum of 36" from rear and side walls, which I did religiously. But now I think they sound much better with more rear wall reinforcement of the bass. Back when they were anchoring my main system I didn't do all that much experimenting with positions because of decor considerations, but I usually kept them 36" out measured from the speakers' backs to the rear wall. I had them as close as 24", but I'm wondering why I didn't try them closer than that. I suppose I thought they'd lose imaging and I'd be excommunicated from any pretense of residence in audiophiledom or something.

    I was in contact with Steve Eberbach a few years back and he was still involved in audio research at the time. He was working with some very talented people on some revolutionary concepts in the whole transducer/psycho-acoustic relationship, but he was obviously still very proud of his Time Windows....and for very good reason!

    Review: DCM TimeWindow 1 Speaker
    Islandbird and I must have read the same comment, regarding Time Windows, at about the same time, that 9" inches would raise and improve one's image greatly. At about the same time the same comment also appeared in Playboy in a John Holmes interview. Must be in the numbers.

    Anyhow, I immediately constructed, although not out of solid black walnut, speaker stands that raised the Time Windows exactly 9" off of the floor with great results. For years I also was neurotic about keeping the speakers exactly the prescribed 36" from the back wall of my room.

    However, now I am forced to place them much closer to the wall in their current room with the same results, improved base and I must admit, only slightly dimished depth of image. The conclusion I have come to after all of these years is simply that these speakers image better under similiar conditions than most other speakers and certainly in in their price range.

    The day that I bought mine I went to the Audio shop knowing that I was going to buy either Time Windows or Dahlquists. It didn't take very long in the listening room to make my solid choice, and it was the imaging that made it. It is still the quality that makes new listener's jaws drop.

    I live in the university area of town and have many neighbors who are students. When any of them come into my house they are invariably amazed to hear music, "sound like that". I am also happy with my role reversal status. I am the only long term elderly resident of the neighborhood who has students ask them to,"turn the music down and please keep it a little more quiet".

    I can't help but think that the current owners of DCM have thier head up their butts. Since I posted this review there has been over 14,000 hits on this post and over 120 posts to this review. These are strong numbers on a dedicted site such as Audiogon.

    Clearly with these numbers in mind, it warrants DCM to once gain offer the Time Windows from this period of time.There new Time Windows are sad commentary to the originals that were produced.

    It is very apparent by this thread and posts that the market continues to exist for the original Time Windows.

    Although DCM produces speakers in the already crowded market of HT. Their home audio is not on par. For a company has to grow its revenues by 10% per year to remain viable, I do not see that in the HT speaker field that is already over populated with HT speakers.

    If anyone from DCM reads this thread, here is a perfect way to reintroduce a classic you already own, with an existing market built in. I know what I would be doing if I was sitting in the DCM Presidents chair. Its a no brainer.

    Islandbird, I really appreciate your comments on DCM's distance from the back wall. I apologize for my previous comments-they were meant to extract information, such as yours. This thread has gotten those most comments on Audiogon that I've ever seen(I've only gotten about 6,000 on mine.). I agree with Ferrari's last comments(I'm actually a horn-guy, but off-axis response of the DCM's allows me to listen to music.). To help people to get the best from the original Time-Windows, I have them on maplewood, with some isonodes under them, a little further than 2 feet from the back wall(one is a corner-one has an opening). I tried those stands that elevated them about 9-inches. I hope you don't care about the bass. Actually, those stands weren't rigid, at all.

    Maybe I should e-mail DCM about this, but just moving my original DCM's less than an inch, brought about a hugh difference in the sound. I was thinking that since this has gotten the most response on Audiogon, that someone can give some pertinent information on speaker placement. I currently have my speakers a little more than two feet from the back walls(one near a corner, one near an opening). The speakers are on mapleboards(Mapleshade)with Isonodes under them.

    Review: DCM TimeWindow
    Mine are now in my downstairs system about 8 feet apart and only about 8-9 inches from the back wall (measured from back of cabinet). They are still up on the walnut stands but those are also up on a quasi raised hearth that's about 14 inches above the carpeted floor. No idea why the previous owner had this configuration built to appear like a fireplace, but I think he must have had a TV in the recess and speakers to the sides out on the raised hearth. Whatever, it sounds damn good with much more bass than I hear from my upstairs system with Talon Firebirds driven by Pass X350.5! The TWs are driven by an old Threshold CAS-1 amp, which I bought at about the same time as the speakers. The imaging isn't superb being that close to the rear wall, but it sure does sound superbly musical. Even FM radio sounds right down there. Bass was never a strong suit of the original TW (which supposedly is why the TW3 was introduced), but I have plenty with them now. It's not the tightest bass, but it doesn't lag and really helps make the room seem much bigger than its 20X28X9' It's just one of those freaks of synergy. A system of my old also-rans never fails to amaze me and anyone else who hears it. My son lusts after those speakers! (over my dead body)

    Review: DCM TimeWindow 1 Speaker
    Islandbird, I appreciate your response. I was hoping to move the discussion into the present realm. I know there is some benefit into elevating the DCM's, as those unstable stands that we had proved. I agree that imaging in the sweet spot is not that great, but with all the responses on this site about DCM's, I'm sure that many knowledgeable people can give information-even though it might come from their memory. You'de be suprised how much their input could provide! I would guess that my speakers are at least 10 feet apart with dissimiar backings(one's a corner, one's an open doorway). I might be able to move them closer together and get a more uniform backing?

    Review: DCM TimeWindow 1 Speaker
    I've got TimeWindow 3's & 7's and they're irreplaceable. It's amazing how you can tweak their sound just by moving them 1/2" forward or back. It should also be noted that the imaging of these speakers can be fine-tuned by simply rotating each speaker by a degree or two (slight toe-in or toe-out). These speakers need to be spiked and, in the case of the smaller TWs, placed on short stands. Shot-filled Lovan Jazz or similar stands may work, though a cheaper solution may be to try cinder or concrete blocks under the speakers. Stable and acoustically inert, concrete is actually a great material in audio. If a concrete block improves performance, it may be wrapped in carpet or heavy cloth to match the room's decor. I would still use spikes or hard cones under the speakers for proper drainage of cabinet vibrations.

    BTW - On the topic of DCM re-introducing the TimeWindow, DCM had some very expensive cabinet making machinery and tools that were used to make the uniquely shaped TimeWindows & TimeFrames. When Mitek bought them out, I believe they SOLD ALL OF IT, solidifying Mitek's objective of running DCM as a value-based manufacturer. I've read some good things about the new TimeFrames; it'd be interesting to hear them.

    I've just recently finished a custom center speaker based off the DCM CX17 to match the TimeWindow Sevens. Steve Eberbach worked with me on the design. It uses the same diamond coated tweeter that the Seven uses and the new crossover incorporates the same "time delay" and tweeter dampening circuits. I have a set of 1a's, 3's and 7's.

    Review: DCM TimeWindow 1 Speaker
    Mmakshak, What problems have you head of? Can you provide a link? I think what Rolando is referring to is that the big advantage the Threes have is that you can compensate for room irregularities with the user controls on the top rear of the speaker. You can adjust overall tweeter output along with separate control over high and midrange level on the ambient (outside face) side of the speaker. To give an example, if you have a wall on the left of your listening area and a door opening on the right, you can bump up the level on the ambient side of the right speaker to compensate. The inboard drivers stay the same as not to affect imaging. In normal a listening environment, all three dials would be straight up.

    I lived in Ann Arbor in the 80's, but couldn't afford these, so had to settle for Timeframe 500's, still giving me great pleasure 19 years later. I just got a pair of Timewindows for a song, but one is missing the serial # and the other the "DCM" logo. On the Timeframes, it's important to set them up with the logo medial. I have noticed that the port on both of the Timewindows is on the right, which makes me wonder if these are both "Right" speakers. Is this a correct assumpution, and if so, how important is it? I'm thinking that since bass is less directional, it may not be a big deal, but I'm not against continued searching for the dream speakers of my youth. Input is appreciated.

    Review: DCM TimeWindow 1 Speaker
    Pcurtin,
    I might have mention before, in the TimeWindow series, only the 3's and the 7's are designed as rights and lefts. The difference is in the ambient side of the speaker. The 3's are adjustable and the 7's are fixed at 6 dB lower than the direct side. It would be safe to assume that you have a pair.
    Rolando,
    I think the thread on the AVS forum that Mmakshak is referring to deals with a problem with one TimeWindow Seven. It ended up being a bad or loose solder joint in the crossover and a blown fuse. The Three's are also a two-way design, only the Seven's were three-way.

    Of all the speakers that Steve Eberbach design at DCM, he said the TimeWindow Three's and Seven's were his favorites.

    Review: DCM TimeWindow 1 Speaker
    Rolando, are you disagreeing with my statement that the TimeWindow 3’s are a 2-way design? I wasn't sure. You are correct in the description of the speaker in your post, but the speaker is still a 2-way design. I also have a set and there is one review of the TW3's from Stereo Review –Feb 92 that mentioned that they were 3-way. I was under the same assumption also; Steve Eberbach was the one who told me they were a 2-way design.
    Hauser 07-07-06


    Review: DCM TimeWindow 1 Speaker
    I just talk to Steve for a better explanation on the TW3’s. As stated before, they are a 2-way design as far as the crossover is concerned. Just a high and low pass filter, but they can act like a 3-way based on the position of the mid level adjustment. With it set to max, you are adding resistance to the 8" driver reducing the midrange output, and increasing the midrange to the 6.5". When it is set to min, the opposite happens. In this position it acts like a 3-way. The 6.5" and 8" are both in the same chamber. There is also a factor of how the back pressure affects each drive when the midrange is adjusted. How does he come up with these ideas? I hope this helps.
    Hauser 07-07-06


    Review: DCM TimeWindow 1 Speaker

    Hi everyone,

    I just found this forum a few days ago doing research, when I stumbled across a pair of TimeWindow 1A's on Craigslist near my house. When I read the information in this forum, and then heard them in person, I plunked down $350 for them. Okay, that was higher than what I’ve seen on ebay, but these were only 15 minutes away, the natural oak is in fantastic shape, and the brown fabric (not foam) is good (couple tiny holes). These sound great! These will replace my Infinity Studio Monitor SM155 that I’ve used for ten years—loud, thumping, but fatiguing.

    I first heard a DCM TimeFrame while I was in Ann Arbor going to college at Michigan. I've always thought one day I’d get "grown up speakers" like DCM makes……

    Anyway, DCM's website doesn't seem to have the manual posted for TimeWindow 1A. Does anyone have a pdf of it?

    And does anyone have a spare CX-17 for sale, having used one for a center channel and leaving the other homeless?

    Does anyone have any technical design info on the sophisticated crossover?

    Thanks for all of you sharing your experience! Your information was very helpful.

    It's interesting for me to read through posts in this topic and see there are lots of others who are still enjoying original Time Windows. I have a set of Time Window 1a's that I bought when I was a freshman in college in 1981. I drove them then and still drive them now with the little NAD 3020 amplifier that I got as a high school graduation present.

    I recall that back then some audiophile magazine had the Time Windows and NAD 3020 as kind of the premier "poor man's" high quality audio system. (Maybe "Sensible Sound"?) Both the Time Windows and the little 3020 have followed me around in my meanderings, sometimes in storage, sometimes not. At the moment both are in use in the living room of my home, and the combination still sounds fantastic.

    I drove the Time Windows for a short time recently with a Yamaha home theater receiver, 80 watts per channel. I thought they sounded fine. But then for fun I reconnected the 20 w/ch NAD 3020 and was surprised at the difference. Much more bass from the little 3020, and overall sound was "warmer" along with the elusive "more musical" description.

    If my current original Time Windows ever give out, I hope I can find another pair on eBay.

    I just recently found this Audiogon website and started reading a bit about tube amplifiers. I have to say I've always been skeptical that amplifiers were much of a factor in a hifi system; I always thought speakers were by far most important and that you could pretty much just plug in any decent amplifier and get great sound. My recent experience noticing how much better the NAD 3020 sounded than the Yamaha receiver has me rethinking things. I'd appreciate any comments people could give about whether a tube amp might make a noticeable difference with the Time Windows over my current 3020. Cheers.

    Hsitz, I has the original 3200 driving the original DCM Time Windows, with an analog set-up. Let me tell you, that the Classe DR 70(which came from the original poster of this thread) was far superior. I also want to say that the Nuforce amps killed this Classe(are you listening Classe?).

    I contacted DCM, asking them about tightening the drivers. I believe that MTX(or that car-stereo company with similar initials) owns DCM now. Anyhow, they said tighten away. I wasn't sure about the tweeters, as they have two tightening areas plus a chalk mark, but I am sure about bass drivers. The problem is this. All I could find was phillips screws on the horizontal axis, and when I got to 4th(the last one on my right, while facing the speakers), I didn't even see phillips screws. Actually, it looked like the fourth bass unit was glued! Now, I'm not asking anyone to take off the outer stocking to check this(although, we determined many years ago, that the DCM's sounds better without that stocking), but those that have the stocking off-could you let me know what you see, in terms of tightening those bass drivers?

    Re: Mmakshak question on 9/10/06--I had to replace a driver earlier this year on one of my Time Windows. I did not find any screws holding the driver in place. It was secured with a black glue like material. I used a hair dryer and lots of patience to loosen the driver so I could remove it. I tried to secure the replacement driver with screws and black silicone--I found that the small screws that I used did not work very well as the wood frame around the speaker edge was so thin that the screws had almost nothing to bite into.
    The black silicone did work well. I left the screws in place and I covered the screw heads with the silicone as well. My Time Windows were purchased new about 25 years ago.

    Thanks, paulhbenson. It looks like my bass drivers are as tight as they will go. Now, I guess I will look to bass traps as further improvements. I'm going very cheap here. One speaker is close to a corner. I've tried moving it away, but, so far, it hurts the sound. 2dhunt, did you read my post on the speakers sounding better without the cloths? I don't remember where I read it, but I thought that question about cloth replacement was answered elsewhere-and it's a common question with DCM Time Windows.

    Got advise to get McMaster Carr foam filter material to replace 1/4" foam grille on TimeWindows. Only comes in grey. Advice: Put dark black (cheap) speaker material under first. It makes the grey appear black and does not seem to effect soud quality. Worked for me to preserve "original" look.

    I don't know if I've stated this. I have my Time Windows about 18 inches from the back wall. They sit on a maple board, but I would suggest that is the minimum distance from the back wall-period.

    I bought a pair of 1a's in '79 and have used them ever since. I'm now moving into a new home, getting remarried and I want to have them refurbished. I'm sorry to read they were abandoned by their manufacturer. So much has been lost in the quality and development of music reproduction. The amps of today don't hold a candle to the electronics of the late 70's in terms of cost of quality. Decent sound is ubiquitous, but quality has been forgotten.

    So, who can refurbish them, recone the speakers, fix the hum (a loose wire somewhere), so forth? It's amazing to me that I've used these same speakers throughout most of my adult life. I just realized that this evening and so, found this blog.

    There they are, in a corner, not hooked up yet. I drive them with a Technics SUV6x, also from that period. Happy listening! They are great, aren't they? I never guessed they would so endure.

    After listening to Wilson Alexandria's, I wonder about the accuracy of DCM Windows. Oneobgyn was gracious enough to let me hear them. One song, The Pretender's, "Private Lies(?), sounded like a completely different song on the DCM's. Although it still sounded good, I knew that it was not same song. I believe it has to do with dynamics. The DCM's lack it, and they are much more inefficient than their specs would have you believe. Yes, tonally they are good. Yes, off-axis response is great. No, they aren't correct.

    Speaker driver technology has come a long way since the days of the Philips drivers used in the original Time Window. The Wilson's are also quite a bit more expensive too, aren't they?

    Review: DCM TimeWindow 1 Speaker
    Only $135,000 a pair. I agree about the drivers' technology being better now. Also, the attachment of the drivers on the DCM's drive(pun?) me nuts. Some drivers can be tightened. One of the four bass units is glued in.

    I have a pair of Time Window 3s I bought new in the early 80s. They have been semi retired for about 10 years because one has a non working tweeter. But, they are in excellent physical condition, and as others have noted, their spacial presentation is hard to duplicate by most other speakers. I am looking to seriously upgrade to a combo 2 channel and Home Theater setup in early 2008. This thread has got me itching to take the TW3s out of retirement and repair/tweak them, so I am interested in all information relating to this. I would use them as temporary rear channel speakers then move them upstairs to go with my old RGR amp and preamp for the game room later. Somewhere I ran across a suggested tweeter replacement but can no longer find the link. Any guidance on repair and upgrade on the TW3s would be appreciated.

    Whats the key to the versioning? 1, 1a, 7. From what I have read the 7 is a 3-way design? The others are 2 way?

    If this deal comes through I will have a pair from 1980 next week.

    I missed out on a pair of 7's last week (if my thoughts about driver# is correct).

    I am still upset about selling my Dahlquist DQ-10's in 1978. That won't happen again.

    I still have a pair of original Time Windows. They probably aren't as accurate, nor as dynamic, as many of the best modern speakers, but they're the speakers I always return to. In fact, I'm listening to my pair as I write. They're just really enjoyable and non-fatiguing, in my experience. I actually wrote a pretty thorough review on Epinions, to which I'll try and post a link. My Time Windows outlasted several well-known speakers in my collection, including Vandersteen 2Cis. I finally sold them (the Time Windows), regretted it, and scored a cosmetically challenged pair cheap, which I refinished and am now using (along with Cambridge Soundworks Towers, AR2axs, KLH 6s, and others, depending on my mood). Really nice speakers, I think.

    When I was a kid, my neighbor had a pair of these. He knew I played drums (for obvious reasons) so he had me over once to show off his brand new Sony CD player ("the way of the future, son"). He even had a flashy TEAC graphic EQ to boot. Man oh man, when he dropped in a Rush CD and all the levels started to jump up and down, I went a little spacey. I had never heard anything sound that amazing. I used to house sit for them and spent a lot of time listening to those Time Windows. But I can't remember "what" the sound was like. And as much as I'd love to hear those speakers again, I wonder if reality would hold up to my memory? Kind of like your old neighborhood looking smaller than you remember. Anyhow, those DCM's planted a seed and I'd like to think my younger self would approve of my "grown-up" rig. (Although he'd wonder what I was doing with all these old fashioned records and this laptop/dac/internet thingy.)

    Review: DCM TimeWindow 1 Speaker
    I bought a pair in the late 70s from Fat Julian's Audio in Atlanta based on Peter Aczel's review. Perhaps it was the amplification I used back then but I never really warmed up to them. Especially when I think back and realize now I could have gotten a pair of LS3/5a speakers for less money. They just didn't image as well as the LS3/5a speakers. And I wasn't into bass that much but I upgraded from a pair of ADS L-710 speakers and felt that the ADS really had bass slam that could produce drum kicks like no others from the period. The Time Windows just couldn't do that well.

    When we were at the showroom in Atlanta one of Julian's assistants A/B's the Time Windows against a pair of similarly priced Magnepans. The Magnepans sounded dull in the highs and my 3 friends and I were all impressed more by the Time Windows although I do recall the Magnepans could throw up a stage quite well even in those days. So maybe my amplification and preamplification just weren't good enough. I sold them to a friend and he's kept them for years and is still happy with his purchase.

    I've moved on to home built Linkwitz Orion speakers which are in another league altogether.

    I'm pretty sure one of the reasons I wasn't taken with the Time Windows is that I love to hear a 2 channel system create a 3D illusion of a soundstage and still do. I know now from experience that a preamp and amp can prevent a speaker from throwing that soundstage. But the LS3/5as can and do and so do the Magnepans -each in its own way. The midrange of the LS3/5a was also much more neutral than the Time Windows I'd love to hear the Time Windows with some of the newer better amplifiers that are out there as my opinion seems quite out of sync with the rest of this group and I sure as heck might change my opinion if I were to hear them again. I do still recall how we four college students all agreed that the Time Windows beat the pants off the Magnepans.

    Incidentally, I don't recall the high end as being dull. In fact, I wasn't taken with that metal dome tweeter at all.

    All due respect to the PR fellow from the new owners, but I used to be an occasional member of Bob Waterstripe's monthly breakfast club out at his house on North Territorial road. If you were the top seller of Time Windows in your store, you were welcome to his historic home for a killer breakfast...then a day of hanging with a few of the other salespeople from around Michigan, listening to the various systems Bob had in every room of the old judge's mansion.

    It was during the recession of the early-80s, and a bunch of failing dealers paid their bills with inventory. Every room was a treat. He had way more hifi than furniture.

    I would love to have seven of the original Time Windows to make a full surround system out of 'em. We used to pair them with Carver cubes in mono...and spiked them from the moment we discovered TipToes. Nothin' quite like 'em back in 1984.

    DCM stood for Drug Capitol of the Midwest, but I like Mitek's spin better. DeCriminalize is ok...but a bare minimum!

    Review: DCM TimeWindow 1 Speaker
    I live in South Africa, and own a pair of ARD Time Windows. As I have it the Time Windows were designed by two students in collaboration, and as a final year project. One of the students emigrated to the USA, while the other - a Joachim Fabianek stayed on in South Africa.

    I bought my Time Windows and still enjoy every moment I listen to them. Just amazing what they can do with the right amplifier. Joachim told me that the best they can do is being driven by a valve (tube) amp, fed by a high-quality per-amp. At the time he suggested I try a Gunter Steinhard amp. After I listened to the combination I agree completely.

    Unfortunately it seems that Joachim has passed on (he lived in East London, RSA), and I can not get hold of anyone that knows anything about him or his family anymore. I dearly would like to try to continue what he was doing. I am not sure, but am guessing that the two students did not collaborate on later designs of speakers. Any info on this will be welcome.

    What I desperately would want to get hold of is a pair of Joachim's Aera speakers. If you love the Time Windows, you will be utterly amazed by what the Aeras can do. Even with the brilliant sound of the Time Windows, the Aeras are just so much better. With the advent of the AV sound systems, Joachim fell on hard times. The last time I spoke to him he offered to sell me a pair of Aeras at just over cost price, as he would have liked to organize some income for his enclosure (cabinet) maker. At the time I could not afford them, but I wish I had rather sold my car, wife, house, etc, and bought that last pair of Aera speakers.

    I just can not describe the tonal quality and absolute beauty of the music they delivered!

    Well, at least still have my Time Windows.

    Sorry! Got so carried away that I forgot to say: According to Joachim, the Time Windows were sold as a matched set. Each enclosure had a matched pair of speakers fitted, and this matched-pair had a matching matched-pair for the other enclosure, and that is why the serial numbers will be consecutive numbers.

    As a salesman then manager for the #1 DCM dealer in the late 70's and early 80's, I can answer a few questions about the original Time Windows, the QEDs (essentially 1/2 a Time Window) , the Macrophones, and other models at that tine.

    Bob Carver started using the Time Windows to demonstrate his Sonic Hologram, on the insistence of our stores' owner trying the Time Windows at our store. When TAS reviewed the Sonic Hologram, Carver told JWC (the reviewer in Atlanta for TAS) to use the Time Windows. The story could be found in TAS issue at that time.

    Depending on which of the 3 men listed below you talked to, DCM stood for either:
    1. Drug Capital of the Midwest (or Michigan)
    2. Dope Capital of the Midwest (or Michigan)
    3. Dats Cool Man

    Bob Waterstripe, Steve Eberback, and Howard Jacks were the men behind the scenes.

    Along with the Dahlquist DQ-10's, the original Time Windows were the affordable speakers to own. At the time, the list price for a set of Time Windows was $660.

    FWIW I used "stacked" QEDs powered by a pair of Kenwood L07M and a Marantz 7C. Pink Floyd's, "The Wall" was awesome. The stack acted like a line source with more of a point source imaging than the Time Windows.

    Yes if you looked at the cost of the materials (Phillips/Peerless drivers and very basic crossover, the box and only wood tops and bottoms, it was certainly a wonder of economics. But it's sound, while not SOTA, was really pretty good, especially for the money!

    Review: DCM TimeWindow 1 Speakers HELP
    I have read several postings regarding the TimeWindows speakers. This is my situation. I have come to help my mom after my brother passing a few months ago and I found a couple of these speakers in his closet. The wood is pretty good but the black cover is in bad shape. He was still using them before he passed and they are still in good shape, actually, I must say I have not heard anything so loud this good.
    I have a doubt in my mind, my mom says I can have them if I want to but I think that if I sell them she could use the money for sure. Should I buy new material, recover and keep them or should I sell them; since they are from 1974 how much should I ask for them? In need advice.
