Alpine RS-SB12

$749.00 USD $850.00 USD

Shallow-mount option

Alpine's Halo Series of subwoofer enclosures deliver sound and style in preloaded sub boxes. Now the RS-SB12 12” subwoofer joins their lineup of space-saving shallow-mount solutions.

The little sub that could

The enclosure contains an RS-W12D2 subwoofer dual-voice coil subwoofer wired to provide a 2-ohm load. This shallow sub features a cast aluminum frame, polypropylene cone, and butyl rubber surround, and handles up to 600 watts RMS (1800 watts peak) so you'll get the big bass you're looking for.

Built road tough

The rugged medium-density fiberboard enclosure is only 5.38” tall, and is covered in tough and attractive black carpet. The included rubber feet can be installed on the top or bottom, so the enclosure can be installed as a downward- or upward-firing enclosure for maximum flexibility. A steel mesh grille protects your speaker from accidental damage.
