I just purchased a new home and I'll have a room dedicated as a HT. The dimensions are 18.5x16 with 9ft ceilings. As I live in Louisiana, we have no basements. The room will be on the 2nd Level of a 2-level home and has no windows. It has floored attic space on 3 sides. I am trying to find the best sub to compliment this set up: Fronts: Infinity Beta 40s Center: Infinity Beta C250 Surrounds: Infinity Beta ES250's AR: Yamaha RX-V2500 Initially, I was trying to match up the finish as the current speakers are all Beech colored (minus the surrounds, which are black). I'm not really worried about that anymore, as I'd prefer sound quality over the appearance of the speakers. I would like to keep the sub size on the small size if possible. I'm just trying to find the best sub to compliment this set up to about $600-700. I've read several posts about HSU, SVS, Mirage, etc. I thought of going with the Infinity SW-12 in Beech, but after reading the FR specs, I figured I'd look elsewhere. I noticed the Canton subs, but don't know much about them. Any suggestions would be greatly appreciated. Thanks!
