"I bought a substantial amount of room treatments from GIK. Absorption, diffusion, bass traps, et all. Treated first and second reflection points, bass traps in the corners, front wall, etc etc. At first, it sucked the life out of the room. I have since continued to move panels, measure with REW, rinse and repeat. Granted, all rooms and gear are different; but, in my situation, it was a complete waste of money. I am down to a couple of panels but those will probably come out too. I found running four subs, speakers with great directivity, combined with Dirac Live corrected to 200hz to be the best solution. The room is lively, but not bright or harsh and the bass is kept tight without bloat. Multiple subs and good speakers are where I would spend the money with RC to wrap it all up nicely. What is really eye opening is removing bass traps and other treatments and seeing a net effect of absolutely zero in REW. The scow my wife gave me when all those treatments showed up was right all along."
A post from AVSForums on the MP50 thread about their experience with room treatment. Think I'll stick with my extensive treatment of the rug on the floor !!!!!!
