I have a pair of QS8's in a 5.1 system mounted on the side walls. On one side of room I had to mount above a door so the top of the speaker is 6 inches from the ceiling. I made the other side matching. I am quite pleased with the sound; and as others have said, the QS's are quite forgiving of placement. Hope this helps.
