They are ADP 370 paradigms. They are about 12" so nothing crazy. Yea, the room is tough, but it is the only room I have available for "home theatre" in my home. The set-up is Paradigm Monitor 7s, ADP 370 surrounds, and a CC-370 Center. Yamaha RX-V2500 (on its way), yamaha dvd player, etc. etc. etc. etc.
