Walt, this is a partial assembly of BG 8 and Fountek drivers. They will be integrated to a baffle with a row of 7" midbass drivers. Actual crossover point TBD based on measured performance. The baffle will be narrow on the side of the tweeter/midranges. Tweeters to the center of the room.
The midbass drivers sound good to 3500 or so, but beaming is an issue over 2000. The idea is to cross the BG8 as low as they will comfortably work. Not sure if 500 Hz is practical, but pretty sure that 1000 is no problem. Biamp and electronic crossover.
Hopefully it will sound decent. If not, I'll move on.

Well -- you do have a vertical string of them -- see where it takes you. When I was dialing in my Altecs initially -- I put to good use a capacitor decade and my RTA and diddled with crossover values on the fly until I could not "see" the crossover point.
Of course you know as well as I do that the "devil" is in the details. I don't know if you're going passive or active in terms of the crossover (please say passive), but since I have done other's speakers and expect more projects I have a nice inventory of large-value polycarbonate (mostly Electronic Concepts) and polypropylene capacitors that serve the music.
