Do the kits come complete with the cross overs completely built and the horn for the tweeter driver? Anyone have photo's of how they braced?

Kits include the speaker drivers, the connector panel, hook up wires, π logo decal and a printed copy of the plans. For larger speakers that incorporate a compression tweeter and crossover network, kits also include the assembled crossover, Zobel woofer damper, and all cable assemblies are completed and ready to install. Every kit containing a compression driver also includes the horn flare and the bolts to mount the driver to the horn.

As for bracing, put a cross-brace in between the woofer and tweeter spanning front baffle to rear panel and side to side. Make them approximately 1" x 1/2" and long enough to fit snugly. We want to preload the panels without bulging them. They also serve as a place to put a sheet of insulation that spans the cross-section, sort of breaking the interior into two sections. Bass will pass right through but midrange and higher frequencies are trapped.
