The "bars" I play are upscale resteraunts. Very few patrons are "tanked", but there is booze-a-flowin'.
All that said ....... my audience has come to expect a certain excellence from me and they all noticed a change for the better since the Bose. It's drastic. The comments are coming in like crazy.

The sound from my kb is definatly a factor in the overall package, but the way this PAS fills a room is better and fuller than anything else I've had....and I've been in stereo for 20+ years. It's wonderful, it really is.
As for the samples ....... you can debate all day long about what sounds best, but in a crowded room with extraineous noise - mono/stereo is a non factor.

Until you all USE this tower, you really can't comment on the coverage. It's unlike anything I've ever dealt with, and it IS an improvement. As long as the sound going IN is excellent, the sound coming out will be the same!
