Home Speaker Asylum

General speaker questions for audio and home theater.

Re: Dahlquist

I have the complete Dahlquist system and I love them (DQ-10s, DQ-1W sub, DQ-LP1 crossover, DQ ST10 stands). I'm sure there are better speakers out there, but they sound so good to me that I am not moved to seek out better (especially since getting better would cost many thousands). Their strong points are well discussed - wide soundstage, accurate sound, and open, airy sound (not a boxy sound). Their weak points are also well known - power hungry and lacking low end.

Yes, the foam in the woofers deteriates in time. I've had to refoam mine 2 times in the last 30 years. No big deal, relatively cheap. My speaker guy says to keep using the foam rather than changing to a rubber.

Mods worth doing:
1. Upgrade crossover network capacitors (inductors also but less noticable impact)- clearer, cleaner sound
2. Mirror image them - improves soundstage
3. Elevate the speakers on stands - puts the mid and high drivers at ear level (assuming you sit when listening).
4. Add the DQ-1W sub. Will need a DQ-LP1 crossover and 2nd amp. This is the biggest change you can make and really makes them perform as Jon Dahlquist designed them to perform.

The other mods such as binding posts and wire upgrades I haven't done and I'm skeptical that you will notice any change in sound with them. Changing drivers is more involved than I am willing to pursue because it impacts the crossover design (impedance considerations). The DQ-10s are so highly regarded in stock form, why change the drivers?

The Dahlquist yahoo group mentioned in another post is a good source of information for all these things I mentioned.
