A triple stacked magnet surrounds an extended voice coil which allows a very long excursion resulting in huge air movement. A specialized CRC pole with integrated cooling fins and an aluminum shorting cap reduce the lag of coils alternating movement while also providing cooling within the motor. The cone structure is suspended by two spiders and our patented H.A.M.R. surround. The stability of the dual-spider along with the even unfolding of the multi-roll surround create incredibly linear cone travel, free of any unneeded movement that cause distortion.The powerful and efficient motor coupled with its highly-controlled suspension give the X-Series subwoofer the ability to create loud and accurate bass in a very small, sealed box. Only requiring 1 cubic foot of air space (.55 for the 10), the 12 X-Series subwoofer can reproduce frequencies down to 40 Hz before rolling off, leaving you with bass that digs deep and plenty of trunk
