Dahlquist DQ-20 Fan club Rant


I just need to say - I have been using DQ-20's for the past 5 years, and recently got the "upgrade bug". So for the past month I've been running around to showrooms and auditioning the latest crop of under-$5,000 Miracle Speakers all of which have glowing reviews, of course. And I've been checking out used speakers that went originally up to $12,000. And you know what - I've given up.

With the disclaimer that everyone's ears are different - I must say that there' justs nothing out there that beats the DQ's (for my particular ears) overall sonically.

There are plenty that have lots of high end zip in the showroom, because they've got metal dome tweeters which will fatigue you real fast at home. Hence so many of the "latest and greatest" hitting Audiogon with bizarre explanations by the owner as to why he's selling 4 month old speakers.
Nobody ever says - "I made a mistake, these suck, but you'll just love 'em. Listen to how real the triangle at the back of the orchestra sounds!"
And there are some that have MORE bass, because they put a big round hole in the cabinet - called a port - that goes, Whoomp, Whoomp, Whoof. (Could somebody let the dog out, please!) To be fair, there are speakers that go lower with good accuracy - but it's nothing that can't be dealt with by adding a pair of quality little subs. And the bass the DQ's do have is tight.
And there are speakers with nicer wood veneers - you want the birdseye maple veneered MDF instead of the cherry veneered MDF - Oh, that's another $1600! Just don't tap the top of the cabinet with your fingernail, you might dent it!

There are NO speakers that I have heard that have sweeter, more coherent, more real midrange and near-highs, period. In combination with my Velodyne ULD, the DQ's can rock, they can do gorgeous vocals, and full orchestra is probably as good as you'll get below $10,000.

There are speakers I've heard that image great, but that is most certainly one of the Dahlquist's strengths, too.

The only thing I truly would wish for in the DQ's is just a bit more zip in the highs.

It's disappointing. I really wanted the fun of some "New Toys", but there is a magic to the DQ's which I assumed was available elsewhere - it's not. My Spicas had it, but they did have much greater limitations dynamically and frequency-wise. I'd have to say that the Vandersteen 3a Sigs were the closest to having that magic and coherency, but not very exciting - and the Green Mountain Continuum 3 was overall the most impressive (but just not quite right for my tastes.)

So what am I gonna do? I'll experiment with the Regnar capacitor upgrade, but I'm not necessarily going to touch the crossovers - that's probably where the magic is coming from. And I'll try a bi-amp configuration. Maybe try a more "modern" Scanspeak tweeter.

And I have this crazy idea to take two pairs, remove the grills, and stack them like quads (on a custom welded rack) with one speaker upside down, so that each set ends up in a D'Appolito configuration. I'd be willing to bet that would be an approx. $1500 set-up that would knock your socks off.

Any other ideas or suggestions out there? I'd be interested in hearing from anyone who's done the Regnar (or other) upgrades. Cheers, Chip

I have a friend who upgraded with the Regnar package and after burning in for a week, it was a significant improvement. More clarity, more natural & musical, faster from top to bottom. The total effect was "Less" of everything between me and the music. I recommend it.
Hi Texasdave - Thanks for the links. The GR Research look interesting, certainly dynamic, and you sound like you have similar tastes and attitudes as I. If I get a chance to listen to them I will. I have also owned the DQ 10's, and while they still have a devoted following and can be "modernized" successfully - the DQ20i's are far superior, being a straightup, time-coherent, 3-way, using Scanspeak mids and tweeters in a minimized (approx. 1/8 wavelength) baffle.

Just as I was ranting and thinking about this stacking thing, I checked a local website and lo and behold there was a pair of DQ20's for sale at $450. So I ran out last night and grabbed 'em. I now have a pair of 20's and 20i's sitting in my living room. I'll first just try running them in parallel side by side and see what I get. Be interesting to see the differences between the 2 also.
I know that the butthead audio philosophers who work for $12 an hour at high end shops will mumble about phase cancellation if you run two pairs of speakers at the same time (unless they're trying to sell you a surround system), but it's bull. It might be theoretically true at low-mids and low freq. in an anechoic chamber, or on the Bonneville Salt Flats - but in a living room, reflections are a much bigger factor and there's sound coming from everywhere at all different angles phases. The human brain is incredibly good at making sense of this.
I have experimented considerably with "combining" two pairs of very different speakers and had some truly spectacular results - even with vintage mid-fi speakers (I live across the street from a Goodwill, and used to have lots of "supply"). I use a separate amp and EQ on each pair so that I can balance the freq spectrum from each set to take advantage of each speakers unique "fingerprint". When positioned properly and eq'd properly (which can take 5 or 6 hours) I have created imaging from really ordinary speakers that would blow anyone's mind - practically psychedelic. In addition, the bass coupling of two woofers close together takes less powerful designs to a new level.

Plus - it's good, clean fun.
But, of course. I've now got a CJ Premier 11a Amp and a Granite Audio Preamp (all tubes). Wouldn't have it any other way! I have tried many solid state amps with them - and here's another audiophile heresy for ya - the most "musical" of them has been a Carver TFM series. I couldn't believe it, but I kept going back to that one.

re: Wiring - I can definitely see the advantage of replacing the older capacitors, with newer "better" ones, but I'm not sure I buy all the "wiring" hype in general, so I actually doubt there'd be any difference at all. But on the other hand - if I/you didn't like it we can always put the old wires back. Same with the Regnar crossover upgrade - I'd rather just take their parts and build an entirely new one, so the old one can go back in with no damage if necessary.
Opalchip, the upgrades make a difference if you know a tech who can tell what parts will make the biggest improvements and what ones to leave alone so that you are not just replacing parts for the hell of it. Try Miller Sound in PA.

Happy Listening.
Opalchip, why don't you let us know how your experiment with stacked DQ20's works out, once you get them dialed in?
