I've said it before and I'll say it again - as a certified bass fanatic, I've listened to almost every sub out there in a LOT of different applications, and IMO there is NO better sub for music than the VMPS Original sub, they simply keep up w/the signal better than anything else I've heard. They re-produce not just the notes, but also the texture of the bass better than anything I've heard. Woven carbon fiber woofer (very high stiffness/weight ratio, and very good self damping), natural rubber surround, and double stacked magnets and a properly sized enclosure all add up to bass that is deep, tight, and "fast".
