I just performed in front of 600 to 800 crazies inside a huge tent, which has the absolute worst acustics you could ever imagine. The Sona 32's performed flawlessly, got lots of complements on the music and performance, gave out lots of cards and booked the same job for the same time next year. The guy who owns the place said the entire system sounded so much better than it did a year earlier, and he thought the old system sounded great. Barbetta also makes Sona 42, which kicks butt. The Sona 32's are bi-amped which punches the 15-inch woofers with 300 watts and the 10-inch horns with another 150 watts. A pair provides 900 watts of highly directional power that can easily fill most large halls with incredible sound, and there doesn't seem to be any fall-off from one end of the room to the other in a 200 foot by 150 foot room filled to near capacity.

As for inputting the sounds, I personally run independent cables directly from my Yamaha PSR-2000 to each speaker, therefore providing the rich quality of stereo. Additionally, I run a pair of audio cables directly from my Digitech Vocalist VR directly to two additional channels, which provides not only superior quality harmony, but additionally excellent reverb. For smaller jobs, you can just connect directly into a single speaker and the results are excellent.

Good Luck,

Gary
