The subject sort of says it all; can I have a 6.1 setup when the couch (main viewing/listening area) is against the back wall? I have already prewired for a 7.1 setup + 2 subwoofers, but was only going to go with 6.1 for now (hopefully). The rear center speaker would be about 4 feet above the couch. The center, mains, and rears will all be around 9 feet from the “ideal” listening area. The rears will be 2-3 feet above the listening level on the sidewalls. So what do the experts say? Also anyone that is or has been in a similar situation, please tell me how it sounded.
