Well I pulled the woofer out of the cabinet and wired to crossover with a tweeter. Connected them to receiver with cellphone connected to it and ran a 500 Hz to 4 kHz frequency sweep and listened to the sound move from woofer to tweeter as frequency rose. YES! :fruit:

Is it normal to mount the crossover to the walls or bottom directly? Should this be mounted with some sort of spacer at the mounting screw areas?

I attempted this in a cabinet and found the HF circuit cutting out until I removed a mounting screw near the HF side.

If you have some scraps of 1/4" ply that works well under the crossover to lift it a little.
You could also use a plastic or nylon washer under the screw head...
Built:
DR 250: x 2 melded array, 2x CD horn, March 2012 plans.
T39's: 4 x 20" KL3010LF , 2 x 28" 3012LF.
WH8: x 6 with melded array wired series/parallel.
Bunter's Audio and Lighting "like"s would be most appreciated...

Well I went out and purchased 1/8 inch thick nylon bushings mounted the Crossover and got no high frequency sound. Uuuugh! Fooled with the connection until I figured out the 4 ohm resistor was not knocked loose of the trace. Seems I didn't cut the lead short enough and when fastening it to the bottom it forced the lead to push upwards and disconnect from the trace above the board. Resoldered resistor lead and remounted crossover. Hot glued the blade connectors on the crossover and the speakOn connector. The female connectors are prone to backing out with the 12 guage wire I am using. All seems good now.
