Hi Wayne,
I've seen you recommend these as an economical way to get
the base X-over, then add the attenuator and HF comp. I'm
all hooked up with spice so I can view the effects of the
attenuator on x-over freq, except that I don't have the
schematics from Eminence to plug into the spice model.
Is that available?
Thx, Chris

Components L1, L2, C2, C3 and C4 are on the Eminence crossover PCB, which are sourced by, and which use the same component values as the corresponding π Speakers 500Hz, 800Hz and 1.6kHz crosssovers. The 600Hz and 250Hz/1.6kHz units are also sourced by Eminence, but are special order items, available only through π Speakers.But for your application - the π 1K6a010dB crossover used in your four π's - It can be made using the Eminence PXB2-1K6 PCB, adding a compensation cable assembly for the tweeter and Zobel damper for the woofer. There are some photos of these addition cable assmblies in the post called "Compensation networks - Photos." And the Spice model for the crossover can be found in the distribution of Spice available here, on the π Speakers website.
