Chas,

Just to clarify, my goal is still stereo, but just a simple setup to include 2 Compacts. No extra woofers (use the Bose) or mixers (use the PA800). Can't get any easier. Always in my car, the choice to take in one or two

I believe from Ian and a few others on the Bose forum (including a Bose tech I had lengthy conversation with) is that a dual system will provide an unbelievable stereo field, which will allow the panning of instruments along with the things outlined by Mac.

I too had the question of what would happen with 2 180 degree mono fields running amok and meeting very weird in the middle? Who knows. I still know, (or at least perceive to hear) something is missing by playing only mono.

I do love the Bose, even mono, but need to investigate the stereo field. I can always sell one, but can't pass up on being my very best.
