The all-new R-Series shallow profile subwoofers are extreme in every way, commanding a tough and rugged appearance with high performance bass output to match.

Alpine takes compact bass to the next level with a state-of-the-art design coupled engineering innovation to accomplish an ultra-shallow profile without compromising on bass level output and quality in anyway. An exclusive dual gap motor structure combined with a powerful neodymium magnet allows for high power handling of 600Watts RMS and 1800Watts max. Moreover, with its bespoke cast aluminium frame and ground-breaking woofer cone design enables an incredibly linear X-max of 20mm ensuring the best possible bass performance.

Alpine’s R-Series Shallow Subwoofers give you the best of both worlds in size and sound.

What’s more, the optional mesh grille KTE-RS12G, exudes a tough look and adds a premium finish to your custom installation, all-while giving your equipment the protection it deserves.

More bass with less space—Alpine’s new Shallow R-Series rise to the top, giving you extraordinary bass performance in an ultra-compact form to suit and fit into virtually any application.

Ultra-Shallow Design

For those looking to add powerful and deep hard-hitting bass to their vehicle but lack the space to add a subwoofer, then Alpine’s R-Series Shallow Subwoofer delivers the same degree of performance and loud sound you’ve come to expect from the R-Series subwoofer product line, but now in a shallow profile that’s designed to fit into most vehicle applications.

Extreme Output

Don’t let the size fool you—R-Series Shallow Subwoofers feature the same 20mm cone 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 light weight 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 off 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-RS12G grille (sold separately) lets you enhance the look of your custom installation for a professional finish, all-while giving the protection your equipment deserves.
