Alpine RS-SB12 10-inch R-Series Shallow Subwoofer Enclosure, 600W RMS, Ultra-Slim Sealed
The Alpine RS-SB10 R-Series Shallow Subwoofer Enclosure delivers the signature power of R-Series bass in an exceptionally compact format. This preloaded, sealed enclosure is built for vehicles with limited space, measuring only a minimal 5.25” deep. It comes loaded with a 10-inch R-Shallow Subwoofer (RS-W10D4), providing robust 600W RMS power handling and the extreme motor movement (20MM X-Max) found in the full-size R2-Series subwoofers.
Key to its powerful, shallow performance is the advanced motor structure, which features a large 4-inch voice coil, a lightweight Neodymium magnet, and Alpine’s Gen2 DD-Linear Magnetic Circuit for low distortion and precise bass control. The enclosure is constructed from CARB compliant 3/4” MDF and includes a pre-installed steel mesh grille for component protection, making it easy to install in virtually any location.
