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.

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

And the cabinets in the picture layout with the Pioneer woofer
- why, they have the same recessed front baffleboard as the JBL 4505WX type cabinet used in the 4320/4325 type speaker - verrry intriguing ...
