Need advice on using subwoofer with Aerial 10T's

Would like to hear from anyone having experience in using a powered subwoofer with Aerial 10T's. My room is 34'L X 14' W with 8' ceiling. The Aerials already produce pretty good bass in this room, but is there a "reasonably priced" (max $2K) sub that works well with the 10T's and would usefully extend the bass response? Or are the 10T's just best left alone? Any suggestions and recommendations would be appreciated.
