Q.  What is so special about the M&D SX woofer?






A.  The proprietary and patented M&D SX woofer moves an extraordinarily large amount of air for its size, over 3X as much air as similar sized bass drivers.  This is achieved through it’s high current, long piston excursion design.  And in the M&D SX woofer, the speaker piston is always 100% magnetically controlled at the end of both directions of travel.
