About this product
ULTRA-SHALLOW DESIGN For those looking to add powerful, hard-hitting bass performance to their vehicle but lack the space to add a subwoofer, Alpine’s R-Series Shallow Subwoofer delivers the same fun and loud sound you’ve come to expect, now in a shallow subwoofer that’s designed to fit in most vehicle applications. EXTREME OUTPUT Don’t let the size fool you – the R-Series Shallow Subwoofers feature the same motor movement (20MM of excursion) as the full-size R2-Series Subwoofers for extreme output in a shallow woofer design. At the heart of the R-Series Shallow Subwoofers is an oversized 4-inch voice coil that houses the lightweight and powerful neodymium magnet for 600W RMS of power handling. Precise Bass Control Alpine’s Gen2 DD-Linear Magnetic Circuit technology, a compact and efficient dual-gap voice coil structure, allows for better control over the motor, resulting in lower distortion and precise bass control.

The new design and enhanced performance of the R2-Series subwoofers offer deeper bass and tighter bass control compared to the previous generation. Updates to the new generation include larger, double-stacked magnets, an integrated Faraday ring, and a Kevlar-treated cone. All of these updates equal unmatched durability and reliable performance, even at high volumes. The R2-W12D4 handles up to 700 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.

Hook this 12-inch CompR subwoofer to 500W of power in a sealed or ported enclosure for intense power and reliability. The Spiralead tinsel emits powerful sound, while ribbed Santoprene surround produces deep, clear, chest-thumping bass notes. This CompR subwoofer has dual voice coils with 2 ohms for flexible system design. Geek Squad Installation Recommended Visit your local Best Buy store for more information.
