Alpine PWV-SB12 BassRev™ 12-inch Powered Shallow Subwoofer Enclosure (200W RMS) - OPTIM Sync DSP Amp

Features:

• OPTIM™ Sync DSP Amplifier: Integrated Class D amplifier uses Alpine's proprietary dynamic bass boost algorithm to extend the subwoofer's frequency response down to 31Hz for huge, controlled bass.
• Shallow Enclosure Design: Ultra-compact dimensions with a depth of only 6-5/8" (168mm) allows for flexible installation in vehicles with limited space, such as trucks and small coupes.
• Preloaded BassRev Subwoofer: Features a 12-inch subwoofer with H.E.D.G.E. (High Excursion Design Gathered Edge) rubber surround for increased linear movement and powerful, deep output.
• High-Quality Construction: Sealed MDF cabinet features a double-brace internal structure for rigidity, minimizing rattles and ensuring distortion-free performance. Finished with a durable black carpet and extended protective grille.
• Flexible Input and Control: Features both RCA (Preamp) and Speaker-Level inputs with an auto-turn-on function for seamless integration into any factory or aftermarket system.
• Adjustable Controls: Includes a variable Low-Pass Crossover (50-200 Hz) and a Phase Switch (0°/180°) for fine-tuning bass output to match the rest of your audio system.
