Alpine W-12S4

Bassline 12″ Subwoofer

Alpine W12S4 – The Bass Series Subwoofers are engineered to deliver deep, hard-hitting bass in your vehicle.

These subs use 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.

What’s more the optimised magnet circuit allows more focused magnetism in the gap which improves efficiency resulting in tighter bass control and more output.
