Re: Dahlquist newbie...DQ-10 crossover question.
A few changes as I used both lists
The 5.6 caps were changed to 6.0 on the other list which matches original caps so I used 6.0uf
I used a diff one for woofers. I have two sets of dq10’s. I used a very big red one for one set and a smaller size but same uf on the other. The larger red one seems to store up for like the canons on telarc 1812 better. On most things like Bach organ deep petal tones 20hz I didn’t notice a difference.
I redid the caps on one for piezo tweeter and left it as it was for second set. I’ve never been able to detect any sound coming from the piezo so it’s a bit difficult to fit the new caps in the space so I didn’t change them on second set.? I got most caps and resistors from madisound but a few from parts express where mills were not available in that size and I found better caps at better prices from parts express. The 5.6 and woofer resistors I got from parts express in the white wire wound ones. I got the woofer cap ?and the piezo ones from parts express too.?
If I were doing it again I would go with the larger size cap for the woofer in the second set.?

Re: Dahlquist newbie...DQ-10 crossover question.
I would start by replacing the electrolytics, and then move on to mirror imaging. ?That will give most of the benefit. ?You could upgrade other caps later, when ready for another project.

Re: Dahlquist newbie...DQ-10 crossover question.
I’m sure I have the complete rebuild list of parts and directions. I just did the xo recapping and didn’t do the wiring or other?things. I can say the new caps did improve bass and slightly tamed the brightness in mid and upper ranges. It’s also true the clarity caps take 20-50 hrs to fully break in.? On one set I changed caps for piezo tweeter the other I did not. I have never heard any sound coming from that driver.?

Re: Dahlquist newbie...DQ-10 crossover question.
Replacing each cap and resistor with clarity caps and mills resistors takes about an hour tops. I’ve done it on two pairs.theres a list of parts from madisound on the site. I can send images if needed.?
I did the second option. To make the mod easier, I just clipped the legs(wire) close to the old cap and twisted and soldered the legs of the new caps. Not too pretty but doesn't affect or diminish sound quality..

Re: Recommendations on Compact Amplifiers
Full range without subs try 300++wpc to start. And be sure to attach large heat sinks to the power resistors. Then either use fans, or lay damp wash cloths, or both, on top of the sinks prior to listening sessions. Otherwise the power resistors will roast at elevated volumes. Naturally this does depend on room size and desired volumes. If the room is small you might squeek by. Either way the sonic results will never approach bi-amping. So as always consider spending whatever funds on bi-amping first. Even then in medium to large sized rooms consider 270ish wpc main amps. Unless tube as then a solid 120w might cut it. Usually you can get by with half the main power on the subs. In many cases a 600+ damping factor 120wpc will suffice. Vintage sealed cab speakers with fast alnico 10"s or 12"s are best. I would advise avoiding all the modern class whatever plate amp sub products. Ported or not, as they really can't match the mains in resolution. And will end up having to be replaced. The DQ10's are quite particular about the equipment upstream. IMHO, the probabilitys of modern compact designs providing the desired results are less than 50/50. This mountain was climbed long ago. So the best advice is to incorporate past experience into the current game plan.?
Bi-amped with the proper equipment the stock 10's are on the short short list of the best speakers ever produced. Unfortunately full range they drop right off the bottom of the page.?
Cheers! DD
Have you looked at the Peachtree line of amps and preamps?? Don’t recall the exact dimensions, but they are rather compact and used ones are available for low prices on the net. ? ? Whatever you choose make sure you have at least 200 wpc or you won't get the sound you want for those speakers. good luck.

Re: Dahlquist respect or lack thereof.
Thanks for the replies folks. ?Pretty much what I expected. I have heard the Time Windows, and they are very nice, but not as versatile as even my lowly m907’s in my opinion. ?Maybe someday I will run across a set of 10s I can restore for fun. ?But for now, I sure like my cabinet models. ?

Re: Dahlquist respect or lack thereof.
Str8wire,
Yes, I’ve heard about the DCM Time Windows, but never had a chance to listen to them. When I chose my DQ10’s, the other candidate was the Bose 901’s, but after my first listen to the DQ10’s, listening to Tchaikovsky’s 1812 overture, driven by a 125 watt Bryston amp, at the Electronic Supermarket/Dino’s Sight and Sound, in Niagara Falls, I was sold! Neil Peart, the drummer from the band, Rush, was still living in the area and had also purchased a pair ... it was a long time ago, gee, 40 years ago, now ... life was good, then! lol
No, I’m not familiar with GR Research. I had Regnar rebuild mine about 15 years ago and while I’ve toyed with modifying them, I won’t bother until they’re in need of repair. It would be interesting for all of us, though, to know what they might find/recommend.

Re: Dahlquist respect or lack thereof.
Bryan,
I’m listening to Shostakovich’s 11th, enjoying it! Thank you for the recommendation! lol Parts of the 11th remind me of one of my favourites, Bartok’s Miraculous Mandarin - that piece gets my blood boiling! Love these speakers! And great on the Vandersteen mention, always wondered how they might compare!
Ok, Will, I can help but ask - did both men sell coke to subsidize their passions? lol?

I agree. Bought my pair in ‘76, they still have the ability to move me emotionally. Crossovers have been rebuilt , woofers too.
Recently added a pair of Vandersteens to the stable, they are fine speakers but am not sure they compare for “the itness factor”
Playing Shostakovich 11th on the DQ10’s is phenomenal.

Re: Dahlquist respect or lack thereof.
There are better more practical options like that new Magnepan for about 1200-1500 which is new and sounds great without rebuilding crossovers and drivers etc which is too much trouble imo
