I am having a house built and the builder's automation/video/sound guy recommends placing 5 speakers in the ceiling in the grand room. Three above the t.v. (front left, center and right) and two behind the viewer. The room is 21'x28' with tile floors, 12' ceilings and is wide open to the kitchen and dining areas. Very hollow area. They install Klipsch 6" speakers in the ceiling.
I can certainly use stand mounted or wall mounted speakers for the front by the t.v. but I have no way to run wires or power to the rear surround speakers and no place really to hang them w/ 12' ceilings.
Personally, I do not think having the speakers up above directing sound down towards the tile floor is the best option, especially for the high frequencies. It's convenient and out of the way, not to mention they look nice, but maybe it works as they are doing this in all the new homes.
Any thought/ideas?
