Alpine RS-W12D4 R-Series 12" Dual 4-Ohm Shallow Subwoofer

The 12” R-Series Shallow Subwoofer with Dual 4-Ohm Voice Coils from Alpine is a high-performance audio component for your car's sound system. Its Gen2 DD-Linear Magnetic Circuit technology and dual-gap voice coil structure ensure lower distortion, better bass control, and precise sound quality. The aluminum dust cap makes it lightweight yet rigid, enabling it to transition sound quickly with minimal distortion and project the bass off the surface of the speaker for hard-hitting yet smooth bass performance.

Key Features

  • 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 cone 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 is controlled by a powerful neodymium magnet for 600W RMS of power handling.
  • 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.
