BTW, I also think your right on in-ceiling mono vs stereo. I can get some imaging in my dining room (9' ceilings) if sitting centered and surprisingly when standing. I might be able to place the speakers if I think about it but I seem to be able to ignore it at the same time.
In another thread, I concluded that in-ceilings are best for ambient sound where aesthetics are overriding factor. I still feel that way. There we also bought up the idea that the QS series might be the better speaker to use for ambient sound if the aesthetics supported it. So, If I was designing a restaurant SQ10s would be my first thought. Here, I'm really trying to figure out if the M3c is worth buying ... over say the less expensive in-ceilings I had in my last ATMOS setup (which BTW is an impossible comparison to do by memory)
