The R-Series Shallow Subwoofers

Alpine's R-Series Shallow Subwoofers are designed to deliver strong bass performance in an ultra-compact form, fitting into virtually any vehicle application. Alpine achieves this shallow profile without compromising on output or quality by using an exclusive dual-gap motor structure combined with a powerful neodymium magnet. This enables 600W RMS / 1800W peak power handling. A bespoke cast aluminium frame and woofer cone design support 20mm of linear X-Max for accurate, high-output bass.

Ultra-Shallow Design

With a mounting depth of just 81mm, the RS-W10D2 is built for vehicles where there simply isn't room for a full-depth subwoofer. It fits most vehicle applications without requiring a large custom enclosure.

Extreme Output

Despite its shallow profile, the RS-W10D2 offers the same 20mm of cone excursion as Alpine's full-size R2-Series subwoofers. An oversized 4-inch (102mm) voice coil controlled by a neodymium magnet delivers 600W RMS of power handling.

Powerful Bass Projection

A lightweight yet rigid aluminium dust cap allows the cone to transition quickly with minimal distortion, projecting bass cleanly for hard-hitting yet smooth performance.

Precise Bass Control

Alpine's Gen2 DD-Linear Magnetic Circuit technology uses a compact dual-gap voice coil structure for linear motor control, reducing distortion and improving bass accuracy. Pair it with the Alpine RUX-KNOB2 remote bass level control for convenient level adjustment from the driver's seat.

Premium Construction

The RS-W10D2 is built with a die-cast aluminium frame for a rigid, resonance-free construction that ensures high energy transfer and long-term durability.
