It is quick and tight and keeps up with the HT's very well. I feel that, musically, it's better than those "one note wonders" from Velodyne and Sunfire. Some may laugh at this but another sub I really like, and currently own, is the Klipsch RSW-15. Very balanced, very tight, and the corner placement in my den with the rear firing woofer and front passive helps it blend seemlessly with my L1's. That and, it makes a great end table!
