Product Description

Alpine SWR-8D2 Type-R 8″ Subwoofer With Dual 4-ohm Voice Coils

Alpine SWR-8D2 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 poly-mica dust cap, which increases rigidity and virtually eliminates cone distortion at extreme volume levels.

Alpine SWR-8D2 Type-R Subwoofers will bring big bass to just about any vehicle. The SWR-8D2 8″ sub features a cone made from Kevlar treated pulp the same material used to make bulletproof vests and its durable HAMR Santoprene surround allows for huge amounts of excursion. This sub was built for bassheads that want the best of both worlds accurate response and otherworldly thump.

HAMRS

The woofer features a High Amplitude Multi Roll Surround (HAMRS), made of Santoprene, that allows a large linear excursion and greater SPL. The HAMRS design allows extreme excursions without sacrificing valuable cone area.

Progressive Spider

The progressive Conex spider has reinforced layer tinsel leads to ensure reliable and consistent control of the tinsel leads and eliminate any mechanical noise or interference often seen in high excursion cone designs.

Compound Radius Curve Pole Geometry

Alpine’s Patented Compound Radius Curve pole geometry ensures a symmetrical magnetic field, while optimizing flux density to reduce distortion and further improve power handling and output.

Oversized Voice Coil

The oversized (40mm), high-temperature, 4-layer dual voice coils offer increased power handling to 350W RMS / 1000W Peak.

Dual Voice Coils

For 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.

Spring Terminals

The spring post terminals are all located on one side of the woofer. The terminals will accept bare wire up to 8 gauge, pin connectors, or single 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).
