Hi Scott
I use the APT 80 right now in my home.
I've used it for a speaker system I built for a chapel as well. There it held its own in connection with 2 beta 8a in parallel used as midrange. I found the 3500 Hz crossover a little too high for the beta 8's but did it anyway. They were pleased with the sound. It is good, but not breathtaking.
In home I crossed it over around 3100 Hz 18 db per octave. Here it is about 9 ohms. Crossed it over to an Alpha 6a. Used 6 ohm in series and 4 ohm parallel to attenuate (I think).
Personally would not use the other horn options because of their frequency responce. But they might be fine in PA.
Another possible option in this price range is the B&C DE10-8 1" Mylar Horn Driver with the B&C ME10 1" Hyperbolic Cosine Horn 90x60. I have not used this yet.
Wayne uses the Vifa DX25 with the Alpha 8a I think. If you have not already done so be sure to check out his site to see if there is anything there that might work for you.
