Eric, it depends on where you're going to be sitting, and that might depend on how big your TV will be, among other factors. If it'll be at the back edge of the carpet in pic 1, then the left surround has a place at the top edge of that window, but on the right side opposite that would be that open passageway. Maybe the present owner didn't go far wrong on the surrounds(excepting the brand, of course)and as Paul suggests, place the QS8s a foot or so lower than his speakers, and pointing straight toward the front without any tilt.
