| 12" | 2Ohm | S2-Series | Enclosed | Shallow |



The Alpine SS-SB12 Subwoofer is a powerful and compact audio enhancement solution designed to deliver deep, rich bass to your car audio system. Its innovative design boasts a 12-inch subwoofer driver with a specialised enclosure, optimising the reproduction of low-frequency sounds. This subwoofer is engineered to provide impactful bass response while maintaining clarity and accuracy in the audio playback. If you’re looking to enhance the punch of your music, the Alpine SS-SB12 Subwoofer offers a space-efficient and performance-oriented solution for achieving impressive low-end audio in your vehicle.

Designed for Tight Spaces

Now you don’t have to choose between bass and space! Alpine’s S-Series Shallow Preloaded Subwoofer Enclosure measures at a minimal 4.5” (114mm) deep to deliver the loud and powerful sound Alpine’s S-Series are famous for, all-while to suit most vehicle applications. Moreover, the “feet” are adjustable in height to accommodate uneven vehicle floors.

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 optimised performance.

Precise Bass Control

Alpine’s Gen2 DD-Linear Magnetic Circuit technology, a compact and efficient dual-gap voice coil structure, allows for better control over the motor, resulting in 22mm of peak-to-peak linear excursion for maximised output.

Optimal Power Match

With dual voice coils wired in parallel for a 2Ω load, the Alpine S-Series 10” Shallow Subwoofer Enclosure is optimised to perform with Alpine’s S2-A55V, KTA-200M, or KTA-30MW amplifiers.
