I have a rather large living room and with the way the ceilings work, along with the opening in the back it is probably an acoustic mess. My question has to do with the front speaker placement. From my center speaker it is about 16ft to the listening position. Quite a long ways indeed. How far apart should I put my fronts. I have read the triangle placement but that won't work because of how far back my couch is. Should they be closer, farther apart, straight, toed in, etc. I have included some pictures to help you get an idea of what my room is like. We just bought this house a few months ago so the walls are still a little bare. The speakers are RTiA7s, CSi5, PC12-NSD.

Standing in front of TV..Ignore the dumb placement of surround, waiting on upgrade so I haven't mounted them yet.

The speakers are currently toed in to point toward the middle of the couch. Also in the picture is XPA-3 and Pioneer VSX-9040TXH and Samsung LN52A650. Thanks.
