Bass production is all about moving air and Alpine's Type-R subs do that better than ever. Advanced suspension features give these powerhouses the extra-long cone excursion needed to push large amounts of air, while the two-piece parabolic Kevlar® treated pulp woofer cone and multi-roll Santoprene™ rubber surround promote accurate response. Best of all, these subs feature shallower mounting depths than previous Type-R subs, so you can fit them into more spaces in your vehicle.Impressive power handlingThe SWR-1043D 10" subwoofer handles up to 600 watts RMS for big-time output, and its dual oversized 4-ohm voice coils offer system wiring flexibility. It works well in sealed or ported enclosures so you can choose what kind of bass you want to hear and feel. The one-piece aluminum frame houses a double-stacked ferrite magnet structure for increased accuracy and power handling, along with a finned, radial heatsink that shunts off excess heat for long-lasting reliability with reduced distortion.
