Alps Alpine North America, Inc. (“Alpine”) is now shipping R-Series Shallow Subwoofers available in 12” or 10” raw or enclosed versions. The ultra-shallow subwoofers deliver the same “Loud and Fun” performance synonymous with Alpine’s R-Series Line, now in a shallow subwoofer designed to fit in most vehicle applications.

 

 

The R-Series Shallow Subwoofers offer a 12” or 10” High-Performance Shallow Bass Driver that’s available in both a 4Ω (RS-W12D4, RS-W10D4) or 2Ω (RS-W12D2, RS-W10D2) dual voice coil (DVC) version.

 

With an ultra-shallow subwoofer design and powerful sound output, the R-Series Shallow Subwoofers provide the best of both worlds in size and sound. Even with a mounting depth of 3.25”, the shallow subwoofers still provide the same cone movement (20mm of linear excursion) as the full-size R-Series Subwoofers, for extreme low-end in a shallow woofer design.

 

At the heart of the subwoofer is an oversized, USA-manufactured 4” voice coil that is controlled by a powerful neodymium magnet and provides an impressive 600W RMS / 1800W of power handling. Exclusive to Alpine is the Gen2 DD-Linear Magnetic Circuit technology, a compact and efficient dual-gap voice coil structure that allows for better control over the motor, resulting in lower distortion and precise bass control.

 

Cosmetic design features like a lightweight aluminum dust cap allow the cone to stay cooler for enhanced reliability with minimal distortion for a deep, up-front bass kick. The die-cast aluminum frame provides rigid and sturdy construction with integrated heat sync fins to wick heat from the coil for uninterrupted performance.

 

For extra protection, an optional Shallow Subwoofer Grille Kit is available in 12” (KTE-RS12G) and 10” (KTE-RS10G) version (sold separately).

 

The R-Series Shallow Subwoofers are also offered in a 12” or 10” Sealed Preloaded Enclosure for those looking for a complete subwoofer application. Measuring a minimal 5.25” in depth without mounting feet, the enclosures are the ideal application for vehicles that lack bass and space.

 

Intentional designs like rubber modular “feet” allow the enclosure to be adjusted in height to accommodate uneven vehicle floors. The feet can also be configured for an upfire or downfire configuration where a pre-installed mesh grille provides a clean finish and extra protection for the speaker cone. The rear panel exposed motor radiates heat from the inside of the subwoofer to the outside of the box for enhanced thermal reliability.
