Maximum bass output

With over 40 years of experience, Alpine has the know-how to deliver the kind of hard-hitting bass you want. The R2-W12D4 12″ sub capitalizes on this knowledge with a new motor structure with double-stacked magnets for deeper bass and tighter sound. Its Kevlar-reinforced pulp cone features a durable HAMR Santoprene™ surround that allows for huge amounts of excursion, and an oversized poly ceramic dust cap supplies rigidity to keep the sound tight. It’s the perfect sub for bassheads that want the best of both worlds: accurate response and otherworldly thump.

A versatile performer

The R2-W12D4 handles up to 750 watts RMS, so it’s ready for your high-powered amp. Its dual oversized 4-ohm voice coils offer wiring flexibility for multiple subwoofer setups. Since it works well in sealed or ported enclosures you’ll enjoy your music the way you like to hear it.
