About flipping the in-cabinet M80's. My 2.40:1 screen will probably be mounted very close to the ceiling. Probably putting ears in line with the next to the top woofer, or bottom mid-range. Inverting the speakers may work best for me. But, I wouldn't know until I've experimented with the arrangement.
