On my occasional visits to the forums i see some wonderful home theater rooms. Most of them use a front-firing overhead projector. What i'm wondering is this - if you are building or converting a room for home theater and you have plenty of money, then why not have a "screen wall" with plenty of depth behind it and locate the projector back there? It would be out of sight and the fan noise of the projector would surely be less audible to listeners. Another benefit is space behind the speakers which can help with imaging and smooth bass response. Granted, most of us don't have a room so long that it has an extra 6 to 10 feet of length beyond the desired theater size. But, with enough budget and enough elbow room, wouldn't you prefer the benefits of this type of room design?
