Alpine - R-Series Dual 12" Voice Coil 4-Ohm Subwoofer - Black

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.

Alpine's Halo Series subwoofer enclosures make it easy to add more bass to your system. The pre-loaded R-Series 12" dual voice coil subwoofer provides plenty of bass on its own, but when you want even more, the optional linking kit can connect two together for double the impact.

The CompRT Down-Firing Subwoofer Enclosures come loaded with a passive reFLEX subwoofer and KICKER CompRT active subwoofers. The patented design of the TRTP was created in-house by KICKER engineers. The new benchmark in ultra-thin, pre-loaded enclosures, the TRTP’s unique shape and beefy construction are the perfect combination of convenience and reliability. Place the TRTP under your truck seat or cargo area for great bass – no grille needed! Covered in stylish black carpeting and built with thick MDF, these tough enclosures take serious power without taking up needed space. Heat is the enemy of endurance. To make our subs even more reliable, KICKER engineers developed Forced-Air Cooling to help our CompRT subs run 25 percent cooler. RoHS Compliant.
