With so many speakers, what would be the required for the ceiling for the "height" speakers? We're dealing with angles, so I'm assuming that the further your listening area is from the source than the ceiling needs to be higher but let's say for a distance of 10 ft. from a TV, any guess about the ceiling height required?
Also, with the added speakers, would smaller speakers but in greater numbers still offer enough dB output or "loudness"?
Budget aside, I can't imagine convincing my wife to let me install so many speakers in our living room
