Okay.. I only plan to have a 5.1 system in my living room. I wish I could think of a good way to diagram my living room.. to help with speaker placement. From what I gather, however, is I am supposed to use these "quadpole" speakers in the back. How high should they be mounted on the wall? Also.. that brings up another question.. How should I place the front speakers? I have an entertainment center that has speaker cubbies at about 5' in height only seperated by 4'6" in horizontal space. Is that enough, or should they be spread apart more?

I am also nervous about not getting a center channel speaker. They sound so good in the systems I have heard. In a store I heard the B&W 602 s3 speakers in action and was very impressed.
