Bill,

The Bose PAS system must be heard to believe the hype--it's all true. The sound you hear with your jammed against the speaker pole (sound colum) is the same level as the sound you hear 60 feet away, even when there is a partial wall between you and the performer. I traveled 3 hours to hear it, and I suggest you do the same if you're serious about buying one. However, keep in mind that if your keyboard has a stereo output, some stero sampled sounds will not sound as rich or full in mono as they do in stero, thus the reason I mentioned a pair of them. And, you hear exactly what the audience is hearing, regardless of where you are in the room, 4 feet away or 100 feet away, or sitting on top of the speaker. It's the same everywhere.

Bernie,

I'll be more than happy to help you with any questions you may have.

Gary
