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.
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.
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.
