I'm working on my HT setup for my living room and I'm unsure what to do in terms of speaker placement. I'm planning on a 5.1 setup but I would be open to other suggestions as well.

The living room has vaulted ceilings and the only logical place for the TV was in a corner. The couch is in the center of the room facing the TV, we spend most of the time on the left "chase" area, but I'd hate to have the rest of the couch sound terrible.

Here is a crop of my floor-plan and some not-to-scale additional drawings of my current setup:

Any suggestions in terms of placement would be greatly appreciated!
