Description
Alpine BassRev PWV-SB12 12″ Slim-Line Powered Subwoofer
The Alpine BassRev PWV-SB12 is a premium 12-inch powered subwoofer engineered to deliver deep, accurate bass while fitting into compact spaces. As part of Alpine’s 2025 BassRev Series, this subwoofer combines advanced acoustic engineering, integrated amplification, and DSP technology to produce full-size subwoofer impact without the bulk.
Designed for both factory and aftermarket systems, the PWV-SB12 provides rich, controlled low-end that enhances all music genres while preserving cabin aesthetics. Its slim-line design makes it ideal for under-seat, trunk, or rear deck installations where space is limited.
Revolutionary OPTIM™Sync DSP Technology
At the heart of the PWV-SB12 is Alpine’s proprietary OPTIM™Sync DSP algorithm. Preloaded into the integrated amplifier, OPTIM™Sync dynamically applies bass boost and pre-EQ specifically tuned for BassRev components.
This technology ensures extended low-frequency performance and tonal balance, producing deep, controlled, and immersive bass that standard subwoofers cannot match. Whether at high or moderate volumes, the PWV-SB12 maintains clarity and precision.
Integrated High-Power Class-D Amplifier
The PWV-SB12 features a built-in Class-D amplifier delivering 400W RMS (800W peak) with advanced control features including:
-
Phase control (0° / 180°) for seamless system integration
-
High-level and RCA inputs for flexible connectivity
-
Variable low-pass filter (50–200Hz, −24 dB/octave)
-
Gain control for precise level adjustment
-
Turn-on mode selection for ease of use
A plug-type adaptor is included for secure and reliable cable termination, simplifying installation in a wide variety of vehicles.
Premium MDF Enclosure with Robust Construction
The PWV-SB12 is housed in a carpeted MDF enclosure with a double-brace structure for maximum rigidity and rattle-free performance. The extended grille protects the subwoofer from kicks, pets, and cargo, while the Alpine-embroidered top adds a premium, finished look.
Despite its shallow form factor, the enclosure is engineered to deliver subwoofer-level bass output comparable to larger, full-size subwoofer boxes.
Groundbreaking X-Max Rubber Surround
Alpine equips the PWV-SB12 with an ultra-wide, durable rubber surround that accommodates maximum linear cone excursion and high SPL performance. This ensures the subwoofer maintains precision, clarity, and punch even during aggressive low-frequency playback.
Seamless Integration with Factory and Aftermarket Systems
Designed for both OEM and aftermarket audio setups, the PWV-SB12 maintains a discreet appearance while providing exceptional sound performance. Its compact footprint allows it to fit in confined spaces, integrating cleanly with the vehicle’s interior and existing audio components.
