Overview

Our take on the Alpine SWR-1043D

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 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.

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 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.

The 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 and 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.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible.

Note: Sorry, Crutchfield cannot ship Alpine products to Guam or Puerto Rico.

It's paired with an Alpine MRX-M55, and it hits hard and tight.

Features

Alpine Type-R Subwoofer: These redesigned, fourth-generation Alpine type-R subwoofers include several enhanced features to achieve even cleaner, deeper bass extension, faster, more accurate transients and even greater output capability than before.

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.

Dual Voice Coils: For increased system flexibility, the woofer has two 4-ohm voice coils. When the voice coils are wired in parallel, the woofer presents a 2-ohm load. When the voice coils are wired in series, the woofer presents an 8-ohm load. If each coil is connected to a different amplifier channel, each channel will see a 4-ohm load.

Push Terminals: The push terminals are all located on one side of the woofer. The terminals will accept bare wire up to 8 gauge, pin connectors, or banana plugs.

Jumpers: Included with the woofer are two voice coil terminal jumpers. These jumpers allow you to easily wire the voice coils in parallel (for a 2-ohm load) or series (for an 8-ohm load).

Enclosure Compatibility

Sealed and Vented Enclosure Compatible: The Alpine Type-R Subs have been completely redesigned to offer more installation flexibility and application versatility (in either a sealed over vented enclosure) to build the ideal sound system in your vehicle. These new designs offer a near 20% reduction in mounting depth, while offering even greater output capability.

Recommended Sealed Box Volume: The recommended sealed box sizes range from 0.5 cu/ft to 1.0 cu/ft. Within this range, the ideal size is 0.75 cu/ft.

Recommended Vented Box Volume: The recommended vented box sizes range from 0.8 cu/ft to 1.5 cu/ft. Within this range, the ideal size is 1.15 cu/ft. A slot port with the following dimensions should be used: 11" (W) x 1" (H) x 18.5" (L).
