The New R-Series Shallow Subwoofers

With an ultra-shallow subwoofer design and powerful sound output, the R-Series Shallow Subwoofers give you the best of both worlds in size and sound.

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 (10cm) voice coil that is controlled by a powerful neodymium magnet for 600W RMS of power handling.

Powerful Bass Projection

A lightweight yet rigid aluminium 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.

Precise Bass Control

Alpine’s Gen2 DD-Linear Magnetic Circuit technology, a compact and efficient dual-gap voice coil structure, allows for better and linear control over the motor, resulting in lower distortion and precise bass control.

Premium Construction

The R-Series Shallow Subwoofers are built with a die-cast aluminium frame for a rigid and sturdy construction to ensure high energy transfer and to mitigate any resonance of the frame.

Protection Grille

The optional KTE-RS10G grille (sold separately) lets you enhance the look of your custom installation for a professional finish, all while giving the protection your equipment deserves.
