A very good xover is from a UK magazine (forgot name) - but the title is:

"A Versatile Active Crossover" by Ben Duncan. It was published in the late 1970's or early 1980s. The xover uses NE 5543A lo-noise op-amps. It has the pcb layouts and schematics and tables for the R and C values. It it Linkwitz Riley 24dB / octave. I built a few of these for friends and they work quite well.

You could also look at the Marchand electronics kits.

thanks my pal
finishing my subwoofer controller,wondering building a high class active crossover to take place of the pro one.[a new pass aleph1.2 is under building as well]
waiting for something important that gonna happen,so have some spare time now,need to do something to kill my time
collecting parts,making pcbs and jointing electronics r the best way for me.

Building it will probably cost you more than buying one.Brhringer has a 3 way 24 DB xo for less than 200$
