I've considered those subs -- too big. Looking for something smaller and a little more musical. Right now I'm leaning toward the Onix Rocket ULW-10 or possibly the UFW-10. The room's big - 18' x 18' x 12' open to other rooms. However, the listening area is not quite that big and I'm not interested in chest-pounding bass. Moreover, those are Internet subs that can be returned if they don't "fill the room." In that case, I can go back to looking at larger subs.
