I have the YST 1500 and can tell you, very few subs in the market come close to it. It has best of both, fantastic for HT duty but when called for music, it is equally tight and controlled, Yamaha has been making subs for quite a long time after they bought out the Swedish compamy Audio Research and inheirted the Active Servo technology from them which they have refined over the years. At least give them a listen. Eastwood audio did a good test on them.
