Alpine SWR-8D4 Type-R 8" subwoofer with dual 4-ohm voice coils

Maximum bass output

Alpine's Type-R subwoofers will bring big bass to just about any vehicle. The SWR-8D4 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.

 

Bring on the power

The SWR-8D4 can handle up to 350 watts RMS, so be sure to choose a suitable amplifier as these subs definitely want lots of juice. Its dual oversized 4-ohm voice coils offer the wiring flexibility you'll appreciate as your system changes and grows, ensuring that you can always pull maximum power from your amp. It works well in sealed and ported enclosures so you can choose what kind of bass you want to hear and feel.

 

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