About the Alpine R2-SB12V
Twice the bass
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.

Features
Driver: The Alpine R2-SB12V loaded enclosure features a single R2-W12D4 12", dual 4Ω 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 4Ω voice coils are wired in parallel for a single 2Ω connection.
Power Handling: The R2-SB12V can handle 300-750W RMS (2250W peak).
Enclosure: The R2-SB12V's ported enclosure design has been optimized for use with the R2-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 R2-SB12V's unique design allows it to be linked to an additional R2-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.

Still in the break in period but the sound and depth of the bass is night and day coming from a 12 inch JL micro sub. Was on the fence about this or the JL ho box but the price won me over and I'm very satisfied. Nice build quality and it fits perfectly in the back of my telluride.
