I redid two sets of Dq10 xo recently using s clarity caps from madisound and some resistors from parts express. If u send me contact I’ll forward parts lists and images with instructions. We just went thructhis couple was ago so should still be on this site?

Upgrading a pair of 10's with original crossovers.
When I look at all the entries in the Database for DQ10 crossover values, they seem all over the road. Is there a definitive source for making sure, before I buy them, that I'm have the correct values? Should we also consider cleaning up this page so there's no misinformation there? My serial numbers are 47627 and 47624 in case they changed over time. I upgraded my xovers on another pair 12 yrs ago but don;t have the documentaion anymore, and I do recall having to piggyback some of them to achieve the correct values (would prefer not to have to do that anymore).
As for brand, I used Solens before. Open to suggestions on other brands, however, I'm in my 60's so spending big $$$ on a caps probably won't even be noticed by my aging ears. My goal is to primarly replace parts that have aged out and no longer up to spec.

Hello Paul
How do you search this group? I have no idea.

My entry under? Orthobiz Should have factory schematics for the crossover values… Maybe definitive enough??

No problem.? You'll be able to see it clearly.

Interesting! If possible Ed make a notation of what it is at 60hz and 120hz.
Thx, DD
I'll measure and post the impedance tomorrow, after I measure it.? Because the woofer is a sealed design there will only one rise at bass resonance.

I need some advice. The DQ-10 has a published nominal impedance of 8 Ohms. I understand this to be an average number.? Somewhere along the line, I’ve picked up that the actual impedance of the DQ-10 varies greatly. Is this correct?? Can you share your knowledge of impedance measurements of a DQ-10 vs frequency? I’ve attached a stock example from an unknown speaker as an example of what I’m looking for. Please excuse my finger scribbling the word “example”.?

This is the published impedance curve for the DQ-10 from their literature:

Re: DQ-10 Speaker Buzz Crackle at certain frequencies
Whoa - before you start unsoldering stuff, pop the grills off and do a thorough check of all the surrounds, cones, and wire connections to the terminals of the drivers. Play something that generates the sound with the grill off and see if you can narrow it down to a specific driver. At a minimum you've pinpointed where the issue is occurring?vs a scattergun approach.

Re: DQ-10 Speaker Buzz Crackle at certain frequencies
Unsolder all the speaker wires at speaker and then run one at a time to find the culprit?
Greetings,
I have a pair of DQ-10's (I am the original owner) that I updated with new Regnar crossover boards last year.? They sound great with the exception of a crackle at certain mid-range frequencies -- and interestingly enough, also when film credits are shown on my projector screen with little else going on.? It is not the grills vibrating and I do not think it is a crossover issue since the components are relatively new.? I had the woofer surrounds replace awhile back (15 years ago?), and while this could be the case again, I think it could be a bad smaller speaker or bad surround on a smaller speaker, but really hard to pinpoint.? So, how do I troubleshoot this to find the right smaller speaker that is acting up?? Is this more likely a foam/rubber surround issue or is this a speaker issue?? So, I thought I would reach out to the collective wisdom of the group.
Thanks

Re: Introduction for lurking member. Sun Valley, Idaho area.
Trust me on this. You want to hear a pair of the 10's that have new or fairly new capacitors in the crossovers. I have owned several Dahlquist models and the 9's (not the 9c's) and the 10's rule especially the 10's. Once you hear them you will insist on getting a pair.

Hi there! ?I have lurked here for a while and figured I would do an introduction. ?I am Steve, aka sunvalleylaw on lots of audio and guitar forums. ?I have had Dahlquist speakers since I was 21 and bought my first pair of DQM-5’s with the nextel finish and cabinet with the “cheeks” from Magnolia Hi-Fi on Roosevelt in Seattle. ?I still have those, and they have been re-foamed. ? I have since added two pair of m903’s, because they are useful as rears in my main system when I am watching TV/video and using my 2 channel system for that, and because they are just nice in smaller spaces, and because I couldn’t pass either pair up for the prices they were being offered. My flagship pair is my m907’s I bought from a vintage audio guy in Boise, who had carefully refoamed them, and had too many speakers. ?Got them for only 150 which I thought was pretty good, already being refoamed, being in good cosmetic shape, and having the original matching stands. ? I don’t have any of the sexy 10’s or 20’s or alternatively shaped Dahli’s. ?But I love my more conventionally shaped ones! ? Will be considering doing some re-capping, and so am hear to learn. ?None of mine have been re-capped, and so I wonder if I should do that, especially with my beloved DQM-5’s, which have always blown me away at how good they are, and how they give that almost spooky imaging, being lonely lowly 2 ways. ?I guess Regnar offers some sort of upgrade to that model. ? But want to learn before I try to do anything, when nothing is really broken right now. ? Cheers!

Thank you everyone...all your input is appreciated.
@Dina...I will order those cap values. thank you

Re: Dahlquist newbie...DQ-10 crossover question.
2/6.0 ufclarity blue, 1-6.8uf,1-15uf, 1-8.2 uf,1-80 or 82 uf, don’t mess with piezo caps they are good hi grade film caps and not bad. Just change to mills resisters. Just double the order for both cross .. end of story. It’s about 49 min each starting from woofer side and work over.?

how about a link to the postings that you made relating to your time at Dahlquist? rgds
Some changes are documented in my .pdf of service materials from when I worked at Dahlquist. They are posted…
