Alpine PWV-SB12 Halo Series 12" BassRev Shallow Powered Subwoofer - Each (PWVSB12)

Looking to get earth-shaking bass without sacrificing space in your car? The Alpine PWV-SB12 is a game-changer. This 12" BassRev™ powered shallow subwoofer packs a punch that rivals full-size setups, all while fitting neatly into tight spots.

Shallow, Sealed Design for Maximum Flexibility

The PWV-SB12 is built to slide into spaces where regular subwoofers just won’t fit—think under seats, against trunk walls, or tucked into tight hatch areas. Its shallow 6-5/8" depth keeps your cargo space intact while still delivering full-size bass impact. The sealed enclosure emphasizes low-end punch and feel, making every beat crisp and satisfying.

OPTIM™Sync Technology for Smarter Bass

Alpine’s proprietary OPTIM™Sync algorithm takes your bass to the next level. Built into the 400W RMS amplifier and DSP, it dynamically boosts low-end frequencies while keeping sound controlled and smooth. Essentially, it’s like having a personal bass engineer adjusting every note to hit exactly where it should.

Built Tough, Built to Last

No rattles, no wobble. The PWV-SB12 features a carpeted MDF enclosure with a double-brace structure, so it stays solid even when cranked to the max. The extended grille protects the subwoofer from pets, kicks, or shifting cargo, while the embroidered Alpine top gives it a clean, premium look. It’s compact, sturdy, and ready for daily use.

Seamless Integration With Your System

Whether your car has a factory or aftermarket stereo, the PWV-SB12 hooks up easily. High-level and RCA inputs give you flexible connection options, and the included wired remote lets you tweak the bass on the fly. You get deep, impactful bass without sacrificing the clean look of your interior.

Powerful Performance in a Compact Package

Don’t let the shallow size fool you. This 12" BassRev™ sub handles 400W RMS and 800W peak power, covering a frequency range from 31Hz to 200Hz. Dual 4Ω voice coils allow versatile wiring options, and variable low-pass filters (50–200 Hz) and phase control make tuning a breeze. You’re getting full-size subwoofer performance in a small, driver-friendly footprint.

Experience bass that hits hard, feels tight, and fits where other subs can’t. The Alpine PWV-SB12 is the perfect combo of compact convenience and powerhouse performance.
