Hi all, Just about to move forward on surround sound and flat screen for my living room. I am planning on adding some in ceiling speakers for rear and possibly for front and center. My living room is a bit awkward in that the TV is setup at an angle to the viewing areas (sofas). I am attaching a rough diagram of the living room. My Wife and I generally watch TV from Sofa1. Guests will sit in Sofa2, but I am most concerned about sound from Sofa1, since that is where I do most of my viewing. I currently have a pair of B&W 200 series, which I have loved for many years, mounted above and behind Sofa2 in the bay window area. I just picked up a Polk CS1 center channel speaker. I want to add some in-ceiling speakers (they are easiest to install in my situation). Minimally I want to add two rear speakers in-ceiling, I was thinking, behind Sofa1, and keeping my B&W's a front. I am not sure what to do with the center channel. After I get my 40" flat screen and mount it on the wall, it would be great to have it on top of the audio cabinet which is what the TV is currently on, for convenience, but what will that do to the sound? I might also go all out, and mount 5 or 6 in-ceiling speakers. In that case I have a couple of questions. 1. Should all in-ceiling speakers be of same size and/or make? 2. What would be best arrangement of the speakers in this living room? Then there is subwoofer placement, but i will hold of on that. Any help would be appreciated.
