Weve done the work so you dont have to with this 12" Alpine dual 4-ohm subwoofer ported enclosure sub box kit.
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. Its the perfect sub for bassheads that want the best of both worlds: accurate response and otherworldly thump. The R2-W12D4 handles up to 700 watts RMS, so its 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 youll enjoy your music the way you like to hear it.
One of the best way to get the maximum bass per watt is a vented enclosure! This dual 12" enclosure allows air to freely move in and out of the box but is "tuned" to a set frequency range that greatly increases the overall output. More air = more bass!
