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 make a statement with their bold new look, and are known for their reliability, small size and big power output.
