Alpine SWR-1043D 1,800 Watt Dual Coil Subwoofer Type-R 10in. 22 lbs.

Alpine SWR-1043D 1,800 Watt Dual Coil Subwoofer Type-R 10in. subwoofer. 22 lbs. The subwoofer works perfectly. There's a small spot on the face of the subwoofer that has been fixed with rubber silicone. Bass production is all about moving air and Alpine's Type-R subs do that better than ever. Advanced suspension features give these heavies 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 Santopren 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. 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. 10" subwoofer with dual 4-ohm voice coils Kevlar reinforced pulp cone with Santoprene rubber surround cast aluminum frame with perimeter venting and radial finned heat sink frequency response: 26-200 Hz power handling: 300-600 watts RMS (300 watts per coil) peak power: 1,800 watts sensitivity: 83 dB top-mount depth: 5-7/8" sealed box volume: 0.5-1.0 cu. ft. ported box volume: 0.8-1.5 cu. ft.

Kevlar Reinforced Pulp Cone: This Alpine Type-R subwoofer has a two-piece structural parabolic Kevlar reinforced pulp cone. Kevlar adds strength and tear resistance to the woofer cone while maintaining the benefits of a pulp cone design. There is also an oversized inverted dust cap of the same material, which increases rigidity and virtually eliminates distortion at extreme volume levels. HAMRS: The woofer features a High Amplitude Multi Roll Surround (HAMRS), made of injection molded Santoprene, that allows for an incredible amount of linear excursion and greater SPL. The High-Amplitude Multi Roll Surround Design allows for extreme excursions without sacrificing valuable cone area. FEA Optimized for linearity and made with injection-molded Santoprene, the HAMR surround is a key part of the suspension system that allows for extreme excursions with accurate, distortion-free control FEA Optimized Spider with Reinforced Layer Spider Integration: An FEA optimized Nomex progressive spider with reinforced layer spider integration ensures reliable and consistent control of the tinsel-leads to eliminate any possible mechanical noises or interference typical of many high-excursion designs. Radial Vented VC Heatsink and Airflow Management System: Alpine's Patented Radial Vented VC Heatsink and Airflow Management System actively manages voice coil temperatures by forcing air directly across the heatsink system. This helps to minimize power compression and ensures reliable long playing time by actively eliminating output-robbing heat away from the voice coil. The new one-piece cast aluminum frame with integrated shorting sleeve uses the entire frame as a heatsink, to allow for sustained power output and handling, even in the most extreme of applications. FEA Optimized Segmented Machined CRC Motor Structure: The new Type-R subwoofer has over 20% more motor force than its predecessor delivering more accurate, louder and cleaner bass with even more control, thanks to its new ten-piece, segmented, double stacked magnet structure. The optimized machined CRC motor structure also creates a symmetrical magnetic field while optimizing flux density to greatly reduce distortion, while further improving power handling and output. Compound Radius Curve Pole Geometry: Alpine's Patented Compound Radius Curve pole geometry ensure for an ultra symmetrical magnetic field, while optimizing flux density to greatly reduce distortion, while further improving power handling and output. Oversized Voice Coil: The oversized (65mm), high-temperature (180°C), 4-layer dual voice coil offers more than 35% more surface area, allowing for increased power handling to 600W RMS / 1800W Peak.
