Introducing a new level of Type-R Series performance:

These redesigned fifth-generation Type-R Series Subwoofers include an abundance of enhanced features to achieve staggering power handing capabilities, cleaner output, deeper bass extension and ultra-responsive control than ever before.

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.
