My sub is one of the original 12" Dayton's. Since I got it, it's been sitting on the carpet a couple of feet from my tv. It sounds pretty good but sometimes it does sound a little sloppy. So earlier this evening I was playing around with some scenes from ROTK. I would play the scenes with the sub on the carpet then put it in the kitchen with lanoleum floors. The sub sounded considerably better on the kitchen floor. My question is, what material should I use to build a platform/stand for the sub? Are there anything "special" that I need to use?
