I am going to be redesigning my HT area, tearing out my garage to use for more important things, like surround sound. Here is a basic diagram of how I am planning the room to be set up: My main question is, with those back speakers against the back wall like that, facing each other.. will that mess up the sound? Like, do the speakers need space on the left and right like all of the diagrams I've seen? My room is going to be long, and I would like to have places to sit on the side instead of directly in front. And also, is the sub going to be OK sitting in that corner there or is it better off near the tv? And I was also thinking of spending way too much money and getting a plasma tv to hang on the wall.. if I did that, would it be good to have in-wall speakers built into the wall next to the screen, and then a center one above it? I carpenter cousin would most likely be building a nice cabinet/wall unit thingy for everything... Well, any thoughts?
