The difference between Randy's results and mine could be related to our room characteristics. I have an extremely live room while Randy has treated his room.
I might be 1/2 way in between. I have not "treated" my room, per se -- but I have followed a "live end"/"dead end" model. The front of my theater is a screen wall (Stewart Studiotek 106") surrounded by burgundy velvet drapes, that extend out on the side walls about 6-8 feet. Here is a photo taken for another purpose:
The back of the room is all sheetrocked walls and ceiling, and is much more live. These surround rears will live on the ceiling of the live end.
