Total waste of money for me. If I showed pics of the ceiling and the walls, most people here would faint. I'm going to replace my receiver with a Denon with Audessey and see how that fares. The problem is, the room is too small and oddly shaped to waste any money on treatments. There's a null where my couch is, and there's not much I could do.
When I move my stuff to the basement, we'll see how things work out.
