I'm not inclined toward soldering irons and wiring. Heck, I don't even change the oil in my car, not that I'd know how.
Someone could make a nice small business out of doing these mods.
Hey all, first post here, but I've been stealing info for a while and used some of the advice off of here to get to where I am now with my system. and at my advanced age I am proud to say I now have the finest system that I have ever owned, and one of the top 3 or 4 I've heard. I, too, changed out the caps on my 1.7's. I thought my maggies were a bit too shrill on the upper and middle end so I used caps that would smooth it out just a bit. Imaging and airiness without the bite was the result and I couldn't be happier. I mostly listen to 2 channel music, but I do have the CC5 and MC1's from Magnepan for the surround channels. Processing and power to the rear and center channels is provided by an Anthem MRX710, while the front 1.7's are currently powered by an Emotiva XPR-2 linked to the Anthem. The 1.7's are power hungry beasts and, before I got the XPR I tried to run them off the Anthem, which is a great unit, but at high volumes the protection circuit would kick in. I also tried running them off of an ancient Sansui AU9500, and an older ST series B&K but couldn't get what I thought I should get out of the maggies. I even had a friend bring over a tube MacIntosh that didnt make the grade either. I tried out an Emotiva XPA-2 and I finally got them to sing! When the dealer offered me a floor model deal on the XPR that I couldn't resist that is what I stuck with. The hunt for a subwoofer, even though the 1.7's aren't too bad on the bottom end, was the most difficult. Don't go by the subwoofer reviews for this. You need to hear it with your system. I went through 5 different set ups at the dealer, including REL, Rythmik, and SVS, but the bass kept its overtones going after the maggies were all done. They all muddied up the music a bit. I finally found a non-ported Martin Logan Dynamo 700 that was very precise, was extrememly reasonable on cost, had a great built in amp and the adjustables that I needed and I was finished....I thought. To me everything sounded great. But the one thing that I had put off while trying to get all the right components together was doing the room correction. The Anthem ARC room correction is acclaimed as one of the best. And, knowing that the Magnepans are real sensitive to placement, I decided to run the ARC. Incredible! The magic finally happened. Anyway, if you are thinking of getting the 1.7's or 1.7i's just stop thinking and do it. I realize I've rambled on but I hope that there has been a bit of info that may be valuable to someone here as previous posts were for me. All the best.
RHanson---Danny Richie at GR Research builds x/o's using premium parts for a reasonable charge. You need only provide him with the schematic.
GKR---Also from Danny is a very special sub that would be incredible with your 1.7's (as well as any and all other dipole/planar loudspeakers), his Open Baffle/Dipole sub using the Rythmik Direct Servo feedback system. You can read all about it on the GR Research website and Audiocircle Forum.
@rhanson739 - As an alternative, IF you could handle the most basic of tasks yourself, on the speakers, I could make the new crossover and you could install it. Making a plug-and-play mod of this , would not be difficult. Thus far, I've not found a method of contacting another member, outside of these threads..
dfarmer...thanks for letting me know my ears are still working ok in my old age! I really felt funny and wondered what I was missing by using that sub that was under $500 and dismissing ones that were over 3 times the cost. One thing I've learned is to not let the price tag determine the value or quality of something. And for those trying to match subs with the maggies....be sure to listen to them WITH your system. For me that ML 700 did the trick.
It is June 11th and I am 200 hours into my Magnepan 1.7 Clarity Cap MR speaker auditioning.
It took a very long 125-150 hours before the Caps finally settled in and I am in a very new world with every blessed file and vinyl disc being a new experience to re-discover. It's like they really have no limitations and there is absolutely no need for a subwoofer in the room I currently have them in. I thought about making a defined playlist of the songs that really exploit the capabilities, except EVERY SONG WORKS for demonstrating these mamas! THERE IS NOTHING THAT SOUNDS BAD!
I will do some sort of detailed write-up maybe a new post or on the MUG Tweaks web site. There needs to be more information made available about how well the Clarity Cap MR's transform Mags.
I need to get back to listening to Everything I have both vinyl and bits.
Just ran across this thread (on October 30th, 2020) while my MG12QR's are playing in my living room now. I upgraded to Clarity ESA caps and Jantzen coils, both with higher voltage tolerances (to give a measure of safety for the 'doesn't get any louder when turning the volume to 11')
Completely new speakers after break-in. The MG12 QR's are very placement sensitive but when dialed in, the music literally floats in my living room and the Maggie's hold their own w/o distortion. I use the same test cuts thru Arcam low voltage gear, a Rega P-3 with upgrades and monoblock amps. I built dovetailed boxes for the new components - they sit nicely behind each speaker.
I'm a retired broadcast engineer and audio nerd without raising my nose to others - if you're happy, I'm happy.
What caught my attention was the note asking if someone does these mods. I have time, winters are long here in northern Minnesota. To solve a turntable feedback problem I've started a one man shop - www.auditoryascent.com and contact me thru there. If it's not ok to post the address I apologise, and feel free to edit it out - is more a labor of love than money maker.
Yes, get a sub woofer and raising the Maggie's 2 inches off the floor helps low frequent dispersion.
Lindsey Buckingham sounding pretty good now....
