Yes Dennis Foley is someone that understands room acoustics and how to treat a room.
I never found treating first reflection points to make any difference. Then again with my box speakers I toed them in 45 degrees per the manufacturers recommendation. FWIW, in my experience treating the ceiling and upper room corners made the biggest difference.
With my Analysis Audio, Quad 57, and Acoustat Model 2s I made some very simple 24 x 48 panels with thin foam and placed them on the back wall. They don't need to absorb much, just upper frequencies and they do the job just fine.
@jrwaudio, if your couch is up against a wall have you tried an absorption panel on the wall behind the couch. I found it helpful when my couch had to be in the same position.
