I have a 20' X 20' living room. I would like to install 7.1 surround sound system in it. I have already had two existing tower speakers and one center speaker. Now I would like to install 4 in-ceiling speakers(brand new) in the ceiling. Where should I put them? How far away from the window wall and how far away between the in-ceiling speakers themselves.
The place to install it is the wall, at ear level, when you are normally seated.
