This is an excellent question, curious to hear from whoever chimes in. P

I'm going to be on Long Island next week, and passing near the Dahlquist facility.? Is there anything to experience, or is it just a parts counter in an industrial park?? Any insight is

William - how much coin are you dropping on this upgrade? Curious.

Impressive Bill!!!

I like those external crossovers! How are they wired below the perf board, just twisted and soldered? also good to see the orthogonal arrangement of the inductors. Greatly reduces interactions.?

The great thing about DQ-10s is, their sound quality never wavers in absolute terms (assuming proper care and maintenance). Which means that as their market price goes down, their overall value goes

I have a mirrored pair of DQ-10’s, DQ-20i”s, DQ-20’s and they have all had tired and failing complaints. I had an open resistor and removed it to find it baked underneath so I removed the rest

Agreed Bill, it is always best to verify. ________________________________ Sent: Friday, September 29, 2023 8:25 AM To: [email protected] <[email protected]> Subject: Re:

It could be both. I have two expensive LCR measuring device's and all the original components have varied measurements to include some expired components. New components can be purchased with tighter

They did not work. At first I thought it was the drivers but it wasn't. They had no appearance of damage, just dead.

I'm curious Jack. ?What happens when they fail? ?What do they sound like (if that can be explained)? ?Do they still work?

I am currently in the process of stacking two pairs of DQ-10s. ?On one pair I changed all the cross-overs caps, the other just one electrolyte cap and the potentiometer.

Actually the little film caps can fail, both of mine were DOA. Always check everything over, do not assume anything is good you have not verified as good.

The 80uf for woofer tend to leak but those aren’t the black ones. Maybe chsnged. The piezo are film caps and don’t fail. The yellow Mexican ones can be checked in circuit with a peak 75

Those look great compared to most!? In my experience, the only capacitors that actually go bad are the small blue electrolytics.? The tweeters need to be checked to really determine the

Yup, unfort they don’t hold value commensurate with sound, I bought both my sets for 350$

I have to say that I love the enthusiasm from people here regarding the DQ-10s and Dahlquist in general. SpongeSound is right in that it is not like a vintage car, but people here give the group the

Yes, I am the original owner and there has been no work (no rewiring) other than the replacement of the woofer surrounds.
