LOL!!!! I meant it in a CLEAN way...
Thanks very much TheFactor.
Thanks ld. It has helped "tighten" things up and has helped imaging. Initially, I started off with a pair of standing 6'x2.5' panels on either side of the room, but that was really intrusive, so I downsized to the one panel that's over the fireplace. My wife was much more accepting once I changed that.
I still have some extra foam and wood frames, and I plan to build a few more panels. One is going to go directly behind the display, and another on the wall to the sub side. I had my wife listen to some jazz (Chuck Loeb-between 2 worlds 1st track) in the sweet spot, and this was at 12dB below reference, but it did not sound too loud at all. She was actually impressed and commented that it sounded "live". That made my evening! Everything is coming together nicely.
