I am shopping a HT system now, and I am interested in the Sunfire Signature subwoofer. Apparently it's received some very positive reviews, and it's size is a major plus for me (which means my wife). I've not actually heard the Sunfire and wanted to know how any owners feel. The other sub I like I have actually heard, and it's the Velodyne SPL1200. However, being a very satisfied owner of previous generations of Carver equipment, I do have some leaning in the direction of the Sunfire.
