I'm having a hard time finding the post you refer to. I am in the middle of reading http://www.madronadigital.com/Showroom/HomeTheater.htmlthough. Perhaps the reason is in there?Have you compared absorption to diffusion, or, are you just going by what Keith recommended? I'm really tempted to try diffusion insteador absorption. But that would cost me time and money. There are good arguments for both.
