John, I got to say it's the best sub I have ever listened too, I consider it the defineing piece of my system, I compared it to the paradigm 2400, and (my ear mind you) felt there was no comparison, I also considered it aganist the servo 15, I found it right there, if not giving the edge to the supernova, it goes real low, and flat out rocks, (check the reviews) and the 15x15 cube is not to much of a physical monster. the room is only about 10x22, I have considered getting a second one, that's how much I LOVE this sub, but think it might be over-kill in such a small room.
