This whole mono vs. stereo discussion has deteriorated. Here is a link to another person from Bose who thinks stereo amplification is best for singles and duos, but really he is pushing the idea of an individual PAS system for each member of a band: http://bose.infopop.cc/eve/ubb.x?a=tpc&s=8206048934&f=4286020764&m=8896074194
Get the picture? What Bose is doing is trying to sell PAS units. If you are single or duo then two units is fine - if you're in a band then one for each member is fine. And they'll drum up whatever psycho-acoustic information you need to justify their sales. So forget stereo - at least a half a dozen PAS units for your church group is what Bose really thinks you should have.

So far, I haven't seen where any amount of facts about acoustics has made any difference to anyone who already had decided what they were going to do with their sound setup.
