Hey Randy,
I would agree with you if they were direct-radiating or if his couch wasn't so far back but with multi-polar types such as the QS8s I am not really sure in this case. A lot depends on room acoustics. It doesn't hurt to try both positions to see what sounds best. I know it's a pain but you'll never really know unless you experiment. And now that I think of it, you may even want to pitch them down towards your listening position since they will be so high up. Let us know what you find out.
