Alpine RS-SB12 12" Halo R-Series R2 Preloaded Subwoofer Enclosure with ProLink

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 Subwoofer Enclosures give you the best of both worlds in size and sound.

What’s more, the pre-fitted KTE-RS12G exudes a tough look and adds a premium finish, all-while giving your equipment the protection it deserves.

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

Designed for Tight Spaces

Now you don’t have to choose between bass and space! Alpine’s R-Series Shallow Preloaded Subwoofer Enclosure measures at a minimal 5.25” (133mm) deep to deliver the loud and powerful sound Alpine’s R-Series are famous for, all-while to suit most vehicle applications. Moreover, the “feet” are adjustable in height to accommodate uneven vehicle floors.

Extreme Output

Don’t let the size fool you—the enclosures feature the same motor movement of 20mm 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.

Reliable Performance

Integrated cooling fins located in the core of the subwoofer help dissipate the heat generated by the rapid subwoofer movement for enhanced cooling reliability and hours of uninterrupted playtime. The unique CoolMount™ Dual-panel mount subwoofer motor further enhances cooling.

Precise Bass Control

Alpine’s Gen2 DD-Linear Magnetic Circuit technology, a compact and efficient dual-gap voice coil delivers linear control over the motor for lower distortion and precise bass control. The preloaded enclosures use the subwoofer frame as bracing for a more ridged design and better bass response.

Powerful Bass Projection

A lightweight yet rigid aluminium dust cap allows the subwoofer to project the bass sound with minimal distortion for hard-hitting, yet smooth bass performance. The included adjustable mounting bracket provides down-fire mount configuration.

Optimal Power Match

With dual voice coils wired in an parallel array for a 2 ohm load, the R-Series 12″ Shallow Subwoofer Enclosure is optimised to perform at its best with Alpine’s all-new R-Series R2-A75M digital mono power amplifier.
