I am currently setting up a pseudo media room area in our basement. The area is...well...odd. The basement is divided down the center (two separate rooms). Because of the placement of doors, closets, etc, we have to have the TV against one of the long walls (~25 ft) in the center and the couch on the other side. The width is ~10 ft. What would be a good type of sound system for this area? Soundbar + sub? Is a 5.1 possible/sound good? I like the idea of getting an AV receiver.
