Alpine RS-SB12 12-inch R-Series Shallow Subwoofer Enclosure 600W RMS, Ultra-Slim Sealed
The **Alpine RS-SB12** R-Series Shallow Subwoofer Enclosure delivers powerful bass output in an ultra-compact package. Measuring only 5.25” deep, this preloaded, sealed enclosure is designed for vehicles with limited space, giving you the best of both worlds in size and sound. It comes equipped with a 12-inch R-Shallow Subwoofer (RS-W12D4), providing 600W RMS power handling and the same extreme motor movement as the full-size R2-Series subwoofers (20MM X-Max).
At its core is a high-performance motor structure featuring a large 4-inch voice coil and a lightweight Neodymium magnet. Coupled with Alpine’s **Gen2 DD-Linear Magnetic Circuit** for low distortion and precise bass, the RS-SB12 ensures reliable, hard-hitting performance. The enclosure is constructed from **CARB compliant 3/4” MDF** and includes a pre-installed **steel mesh grille** for component protection.
