I've posted this same question in another forum, but wanted to see if anyone in here knew this answer. Here's the problem. I have looked at both 5.1 and 7.1 systems. I'm working with a space that is 17' x 12 1/2'. The set up is shaped like an "L" with the upper portion of the room dedicated to the home theater. So no back wall to work with. And in a space that is 17 x 12 1/2, would 7.1 be an overkill? Or with the right speakers, could I get it to work? What's the thought out there?
