The Alpine W-SB12V is a preloaded 12” Bass Series vented subwoofer enclosure featuring an Alpine W12S4 subwoofer. Its precision-tuned ported design delivers deep, aggressive bass with controlled output and efficient airflow, while the wedge shape maximizes available vehicle space.

The W12S4 delivers 250W RMS (750W peak), a 22Hz–200Hz frequency response, 88dB sensitivity, and a 4Ω single voice coil. The approximately 44L vented enclosure features optimized internal volume and a curved port for improved bass extension and efficiency.

Designed to align with rear seat angles, the enclosure measures 17.5” W × 20.5” D × 17.5” H and weighs 44 lb. Durable MDF construction, premium black carpeting, and an embroidered Alpine logo provide a clean, durable finish. The W-SB12V is compatible with the KTE-12PG protective grille, with the Alpine S2-A60M mono amplifier recommended for powering the system.
