Alpine SBL-S12S4 Bassline 12" Single Subwoofer

In Store Only Alpine SBL-S12S4  Bassline 12" Single Subwoofer

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

The SBL-S12S4 combines the new Bassline 12" Subwoofer with a perfectly matched custom sealed enclosure, precisely designed and engineered to produce the best sounding bass.
