The Velodyne DD15+ allows you to optimise your audio to what you might prefer. For example, you might prefer to have a different bass sound and feel to that to what you are listing to; like when you are gaming you might want a different sound to when you are watching a movie. furthermore, the energy recovery system amplifier is over 95% efficient and dedicates nearly all of it's power to the bass reproduction with virtually no energy wasted as heat. which in-turns adds to the life span of the SUB.
The great thing about the DD15+ is that once you listen to it you're going to have a hard time finding another sub-woofer which substantially delivers more output or better sound. also there are not many products that delivers a tuning/EQ capability that can match that of the DD-15+.
