Dahlquist DQ-10 Passive Crossover


Hello,
I'm a new forum member. Do we have an electrical engineer or crossover guru in our midst who has done an exhaustive analysis of the DQ-10 passive crossover and would like to share this information? It's certainly not a textbook series layout and quite frankly some of it baffles me. Is it brilliantly laid out or just a compromise to get it to market? I've mirror-imaged my DQ-10s, changed out the midbass, bypassed the poly caps and replaced the 80 mfd electrolytic with a metallized poly, and I'm a speaker diy'er, so I'm not a passive listener. I'm sure that I'm not the only one who'd like a definitive explanation of the crossover design.

http://www.regnar.com/ (offers rebuilt parts etc, think they used to sell an alternative x-over)

I eventually warped the woofer voice coils in my dq-10's (after I melted the wax off the x-over boards & toasted the tweeter level control)
DQ-20's well regarded & much simpler x-over & driver complement
Burning out your speakers is hardly relevant to my request for DQ-10 crossover information. Maybe you should get Voice of the Theatres.
