Building on Alpine’s long heritage in subwoofer engineering, Alpine created a subwoofer line that could spread the passion for deep, hard hitting bass. Bass Series subwoofers use 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. Bass Series subwoofers are known for their reliability, small size and big power output.

The SBW-D12S4 combines 2 of the new Bass Series 12″ Subwoofers with a perfectly matched custom sealed dual enclosure, precisely designed and engineered to produce the best sounding bass.
