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.

Powerful Bass Projection

A lightweight yet rigid aluminum dust cap allows the R-Series Shallow Subwoofer to transition sound quickly with minimal distortion and project the bass off the surface of the speaker for hard-hitting yet smooth bass performance.

Premium Construction

The R-Series Shallow Subwoofers are constructed with a die-cast aluminum frame for a rigid and sturdy construction. For extra protection for the shallow subwoofers, an optional Shallow Subwoofer Grille Kit available in a 12" (KTE-RS12G) option (sold separately) provides a steel mesh grille that protects your investment.
