Alpine R2-SB12V Halo Series 12 Linkable Ported Subwoofer Enclosure

Alpines Halo Series subwoofer enclosures make it simple to add bass (and more bass) to your system. Youll get great bass response from a single box, and when youre 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 Alpines 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 Alpines 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 enclosures trim for a neat, coordinated look.

R2-SB12V Features
Driver: The Alpine R2-SB12V loaded enclosure features a single R2-W12D4 12, dual 4 voice coil subwoofer driver. The next generation R-Series driver features a Kevlar-reinforced pulp cone with a polypropylene/ceramic composite dust cap and a High-Amplitude Multi-Roll (H. A. M. R. ) surround. The driver also features two large double-stacked strontium-ferrite magnets for increased motor strength and excursion. A custom-designed cast aluminum frame and a dual-flare pole vent optimize airflow for driver cooling. Both 4 voice coils are wired in parallel for a single 2 connection.
