About the Alpine R-SB12V
Double the fun
Double the fun
Alpine has been pumping out great sound for over 40 years, and now their Halo Series subwoofer enclosures make it easier to add more bass to your system. You'll get the low end you're looking for from one box, but when you want to expand your system, you can add a second enclosure and the optional linking kit to create a single two-speaker system with double the impact.
Dishing it out
The R-SB12V comes loaded with Alpine's R-W12D4 subwoofer wired for 2-ohm impedance. The sub's Kevlar-reinforced cone and Santoprene surround give you solid bass response at power levels up to 750 watts RMS. The ported enclosure is tuned to 35 Hz to maximize performance.
Getting it together
Two R-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 trim for a neat, coordinated look.

Driver: The Alpine R-SB12V loaded enclosure features a single R-W12D4 12", dual 4Ω voice coil subwoofer driver. Based on Alpine's legendary Type-R subwoofers, the new R-Series driver features a Kevlar-treated cone with Santoprene surround, allowing the driver to deliver up to 19mm of X-max travel. This, along with a new method of attaching the spider and cone to the voice coil, provides superior rigidity to the motor structure, allowing for increased accuracy. Both 4Ω voice coils are wired in parallel for a single 2Ω connection.
Power Handling: The R-SB12V can handle up to 750W RMS.
Enclosure: The R-SB12V's ported enclosure design has been optimized for use with the R-W12D4 driver, and has been tuned to 35Hz for deep, powerful bass. It features a rigid, heavy-duty MDF construction that's been wrapped in attractive black carpet, with a smooth black finish and silver trim on the front face.
Enclosure Linking (Optional): The R-SB12V's unique design allows it to be linked to an additional R-SB12V (sold separately) using the optional KTX-H12 linking kit. This features an aluminum rear link-plate and an attractive, steel-reinforced ABS front linking bracket that securely locks the two enclosures together.
Terminals: A single rear-panel terminal cup houses a pair of binding posts for connection, accepting up to 12 ga. speaker wire. Both of the driver's voice coils are wired in parallel for a single 2Ω load.
