I'm sure the QS8's would work on either the side walls (farther back, as John suggested) or on the back wall.

My comments are necessarily colored by my experience. I previously had "the couch against the back wall" and the QS8's mounted above/behind the couch on the back wall. I thought it worked VERY well.

I understand your concern about the wiring and the elegance of the installation. It'll be great whatever you decide. Have fun!
