Hey guys, I am looking to upgrade my current subwoofer (Velodyne VDR-10). The Pawn American close to me has a used Bob Carver Sunfire MKII for $500. It looks to be in pretty good condition, and I know this is a $2500 sub and is a beast. I also am looking at the Definitive Supercube II, I would like a Supercube I but at $1100+ its a little out of my price range. My local Def. Tech. dealer said he would bargain with me on the Cube II to around $700 as the new Cube models are coming out next spring he said. The reason for the upgrade is that I am looking for a sub that is more accurate with music, but can still slam movies fairly well. I dont have a very big theater room (12'X15') and am not looking to spend over $750 for the sub, What do you guys think?
