We are doing a remodel on our downstairs area and have everything framed and ready to run wire. I want to put in a 7.1 surround system and am trying to figure what speakers should be in-ceiling or in-wall. The room is 15' long and 11' wide. The TV will flush mount to the wall approximately 5.5' above the floor. Chairs will be (need to be) against the opposite wall so i will have about 13' from chair to TV with the TV at one end and the chairs flush to the back wall (this is a must). There will be a solid wall on the left and a half/pony wall on right with an open doorway. The center channel will mount under the TV and on top of cabinets. I am planning on buying speakercraft in-wall speakers with the adjustable tweeters. The L/R back speakers need to go in the ceiling along with the L/R surround. The L/R back speakers will be directly overhead of the chairs. I am wondering if that will be too close? I was thinking of aiming the tweeter (L/R back) directly into the back wall? I am unsure what to do with the L/R front as far as in ceiling or in wall. With the adjustable tweeters does it matter if I go ceiling or wall? Or if I have about a foot of wall space on either side of my TV should I place some in-wall mount speakercraft in that area which would give me four in-ceiling and two in-wall? Lastly, we are ordering cabinets that will be wall to wall along the base. The center cabinets will be ordered with no fronts so we can attach black speaker cloth to the fronts and then all the components will be hidden. I want to place the subwoofer in one of those cabinets. Will this create a problem with vibration of the cabinets etc? I was thinking of placing in a foam mat for the sub to sit on if it did create a problem. I really want everything hidden so I want the sub tucked away with everything else and there wont be any other practical location for it to sit. Thanks
