Thanks all for your opinions! I need to clarify a couple of things:

(1) The room configurations do not allow for wall-mounted surrounds (open on one side and window on the other)
(2) If I were sitting in the center of the couch, the surrounds would be at the 4 and 8 o'clock positions (probably closer to 5 and 7), and about 1 ft behind the couch.

I know it's not an optimal set up but WAF is an issue. New question: is 1 ft too close and will it result in localized sound?

Thanks,
