O.K., so here's the final schematic and a proposed low-cost parts list.
For those who haven't followed this project from the beginning, what's important here is that this is a generic solution to building a DIY 800 Hz MF, 7 or 8 kHz UHF 3-way crossover for a variety of JBL woofers, 16-Ohm compression-driver midrange, and 07x/240x UHF drivers without having to mess with tapped inductors (autotransformers).
It is derived from combining N200B (LX200B) and 3105/6 (N7/8000), in cascade. I've tested it with 2235H LF, LE175, LE85 (2420), and 2446J MF, a bunch of different horns/waveguides, and 2402H (075), 2404H-1, 2406H, and 2407H UHF. It may also be suitable for use with 222x woofers.
Connect LF and HF inputs in parallel for single amp, or biamp passive, as shown. For triamp, separate the UHF section (bottom), as well.
Disclaimer: As with all DIY projects, mileage may vary.
