With an ultra-shallow enclosure design and powerful sound output, the 12" S-Series Shallow Preloaded Subwoofer Enclosures give you the best of both worlds in size and sound. DESIGNED FOR TIGHT SPACES Now you don’t have to choose between bass and space! Alpine’s 12” S-Series Shallow Preloaded Subwoofer Enclosure measures at a minimal 5.25” deep to deliver clean and reliable bass performance in most vehicle applications. POWERFUL PERFORMANCE The SS-SB12 features a 2” voice coil inside of a lightweight yet powerful neodymium magnet for up to 300W RMS of power handling. This combined with a front-mounted magnet motor allows the enclosure to have an extremely shallow footprint while maintaining powerful bass performance. ADJUSTABLE MOUNTING OPTIONS Four adjustable, foam-padded steel mounting brackets allow for flexible installation in many areas and vehicle types, while the foam reduces vibration during play for optimized performance. PRECISE BASS CONTROL Alpine's Gen2 DD-Linear Magnetic Circuit technology, a compact and effcient dual-gap voice coil structure, allows for better control over the motor, resulting in 22mm of peak-to-peak linear excursion for maximized output.
