Default active crossover

Hi there, I am looking for a complete 4-way crossoverdesign, LR-24dB. Does anybody know where I can get the complete schematics/pcb?
Its going to be an active system with Vifa/Scanspeak 4way with 2 woofers with 2x5 Aleph-3 amps on it. Anybody???
Thanx!

I've done a two way 24 dB LR design for my electrostatic system, the schematics layouts and parts list is on my site.


I'm gettting ready to do a 3 way design for an all vifa speaker. I'm trying for the most for the least type of thing. I'm using a pair of $60 XT-25 tweets, and 4 M10 mids in an MTM design. I'll be using a pair of P17's per speaker in a TL. The crossover will be all active with LM3875's on the bass and mid and LM1875's on the tweet. My active driver box will also have line level outs if you don't want to use the chip amps.

Default Another option maybe

Look at S. Linkwitz's site if you haven't already.

(BTW, this is the same "L" as in the LR-24db)

Schematics & lots of info, and reportedly excellent (but expensive) ready made x-overs.

When will be the all-vifa project ready?
I'm eager to see the project choices, since I also plan to use 2 P17s per box in a TL, but in a 2 way system with a heil tweeter (one of the smallest heils tough).

Cheers

Andrea
