The SBW-S12S4 combines the Bass Series 12” subwoofer with a perfectly matched custom sealed enclosure, precisely designed and engineered to produce the best sounding bass. The SBW-S12S4 subwoofer uses a polypropylene and mica damped cone assembly to keep the cone stiff and light for great sounding bass tones, whilst the high-excursion polyfoam surround provides high output bass.
Building on Alpine’s long heritage in subwoofer engineering, the SBW-S12S4 subwoofer enclosure spreads the passion for deep, hard hitting bass.
