The room where our TV is located isn't the most HT friendly out there. The room is 11x22 with a fireplace on one short wall, with the other short wall being half open (half wall for 5', 4' opening and then a '2 full wall). There's a big window on one of the longer walls. Basically the TV can either go in the corner with the half wall or on the 22' wall. We originally put the couch on the 22' wall and the TV in the corner. In currently in the process of buying a RPTV, new receiver and speakers (axiom m22i's, etc.. ). With the way things are, the surround isn't going to be all that great. Here's 2 pics of the room.

So my surround options for this setup aren't all that spectacular. My other option is to put the couch under the window, te TV across from it (glare issues, lopsided room) and then I could have a decent 5 channel setup.

My question is, would a 6th channel even be feasable then? I'd have to mount it right behind the couch above the window. Or I could go with a 6th and 7th on either side of the window. Would this be worth it? Should they really be placed farther behind the listening position?

Thanks..
