I just purchased a 7.1 system for my basement and I need help deciding on where to place the 100W per channel speakers. (My receiver does put out that much power). Attached is a diagram of my basement. If you also have a suggestion on how I could rearrange the furniture for better sound and speaker placement, that would be great. Everything in the room is moveable except the bar, which is only about 4 feet high. I appreciate anyone's imput. Thanks!
