Alpine PWV-SB12 BassRev™ powered subwoofer with 12" sub and 400-watt amp

Big bass for small spaces

Alpine's PWV-SB12 BassRev powered subwoofer serves up the extreme low-frequency bass sound you want from a sealed enclosure that'll fit almost anywhere, including behind the seat in a pickup. This sturdy double-braced MDF bass box delivers maximum punch from its high-performance 12" woofer and onboard 400-watt amplifier. Carpet protects the enclosure from nicks and scratches, while a metal grille protects the speaker cone from damage.

The BassRev woofer

Alpine designed the PWV-SB12 to work with their OPTIM™ Sync DSP amplifier, which uses a proprietary dynamic boost algorithm that extends the low-frequency response, giving you the biggest bass possible from such a shallow subwoofer. The sub also features Alpine's HEDGE (High Excursion Design Gathered Edge) surround that allows the woofer cone to move with great linear freedom while still under tight control.

Power and control

The Class D amp — rated at 400 watts RMS, 800 watts peak — features adjustable gain and low-pass crossover controls so you'll be able to better match the sound of the powered sub to the rest of your system. A phase switch and a wired remote ensure you can obtain the most impactful bass from the driver's seat. Speaker-level inputs with automatic turn-on help you install and integrate this powered sub into almost any factory system.
