The layout of the band is three forward (guitar, dobro, fiddle and all sing) and one back (bass). I placed the wedgehorn squarely in front of the middle front person. I had it hooked up to a QSC amp and Rane EQ.
It ran like a champ. All three of us could hear it well. The high end was way better than typical cheap and muddy monitors. It's the best experience we've had supplying our own monitors (still doesn't beat our experience playing festival shows with pros running the sound - I'm just a musician handy with a tablesaw). I thought it was a real success.
The rest of the band was rather mute on the experience, but you see, my job is to buy the gear, maintain it, set in up, run it, and their job is to kvetch about it when it's less than perfect, so I interpret it as tacit approval.

A couple of things: I use almost all condenser mics since they sound so much better for acoustic music. I run them fairly hot so that I can "work the mic" (lean in for lead, back off for harmonies). The person in the middle commented that there was some muddiness when I was in close to the mic usually talking between tunes probably from maxing out (I didn't hear it off more to the side). I need to balance things out better with levels and such.
I need to learn more about EQ. I ran flat except I canceled everything out below 80 per BFM suggestions. I am a rookie at EQing. It's also tough to think about music and engineer the sound at the same time.
Wish I would have read more posts on here before I finished the cab; I think I would have done the melded array and put a Beta 8 in it (maybe less likely to max out?).
I am hooked on speaker-building. I cannot decide what to build next. I may build another wedgehorn just to totally bath us in sound, but then I think a pair of SLAs with a auto tuba would be nice for the home, and I am also considering a pair of DR200s and a Tuba24.
Question: I have a pair of 15" JBL EONS which so far I've been pretty fond of. Will I be happier with a pair of DR200s with a Tuba24 or is it 6 of one and a half dozen of the other? Part of it is I just like to build stuff.
