Alpine R2-SB12V Halo Series 12" linkable ported subwoofer enclosure

Twice the bass

Alpine's Halo Series subwoofer enclosures make it simple to add bass (and more bass) to your system. You'll get great bass response from a single box, and when you're ready to expand your system you can add a second enclosure and the optional linking kit to create a two-speaker system with double the impact. 

Laying it down

The R2-SB12V comes loaded with Alpine's updated R2-W12D4 subwoofer wired for 2-ohm impedance, for solid bass response at power levels up to 750 watts RMS. The ported enclosure is made of rugged 3/4" MDF with a stylish black carpet covering and is tuned to 35 Hz to maximize the lows.

Putting it together

Two R2-SB12V enclosures can be linked using Alpine's KTX-H12 linking kit (sold separately). Heavy-duty steel front and rear linking brackets connect the enclosures for a compact, sturdy dual-subwoofer solution. The silver linking brackets match the enclosure's trim for a neat, coordinated look.
