The numbers on the Captivator don't paint the picture at all. Archaea's room is just a bass eater, with walls flexing... I am going to go over to Carp's sometime soon. I might take a 15H with me (got the 2nd today!) and do a comparison with it there. I have taken it there before and it performed great in his space, and imagine the cap with his amp will crush it.
I updated my post for terminology clarification.
I agree with Counsil on the SVS. I was very impressed with its performance. In fact I am going to keep an eye open for a deal on a pc13 ultra for behind the living room tv (across a corner beside fireplace). A used one went in Raytown for like $700-$800 recently, and I am now disappointed I didn't jump on it.
