This combination provides deep, clear bass while taking up minimal space in your vehicle. Enclosure: The sealed enclosure is made of heavy-duty MDF (Medium Density Fiberboard), providing exceptional acoustic efficiency and deep powerful bass. The enclosure is covered in sleek black carpeting with the Alpine logo embroidered in white on one side for a refined look and added protection. Mounting: The RS-SB12 subwoofer enclosure includes rubber feet for installation in each corner of the enclosure. Eight rubber feet and four spacers let you vary the mounting height and allow for placing the enclosure on uneven surfaces. A single rubber foot can be installed, providing 1/2" of mounting height. If two feet and a spacer are used, the enclosure will sit 1-1/4" above the mounting surface. The RS-SB12 is optimized for mounting in a down-firing orientation, but includes mounting holes on both sides of the enclosure, allowing for up-firing foot placement as well. Note: The embroidered Alpine logo will be upside-down if the enclosure is mounted in the up-firing position. Speaker Terminals: A single pair of spring-posts are mounted on one side of the enclosure in a recessed terminal cup, accepting pin connectors, single banana plugs, or bare wire up to 10-gauge. The subwoofer's dual 4Ω voice coils are internally wired to present a 2Ω load at the spring posts. Power: The Alpine RS-SB12 enclosed subwoofer can handle 600W RMS (1800W peak). Dual Voice-Coil Driver: The pre-installed Alpine RS-W12D4 features the same motor movement (20mm of 1-way excursion) as the full-size R2-Series subwoofers, providing extreme output in a shallow woofer design. A powerful neodymium magnet and 4" voice coil allow for up to 600W RMS of output, while Alpine's Gen2 DD-Linear Magnetic Circuit technology provides exceptional control over the motor, resulting in precise bass control and lower distortion. Integrated cooling fins located in the core of the driver along with Alpine's Unique CoolMountT Dual-Panel motor-mount help dissipate heat and enhance cooling.
