Groundbreaking Alpine Halo design with next-generation R-Series Subwoofers for more accurate and authoritative bass.
This new designed ported subwoofer enclosure can be used as a single enclosure or as part of an integrated dual subwoofer system.
Alpine's Halo Series subwoofer enclosures make it simple to add more bass to your system. You will get a 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.
A subwoofer enclosure that sounds as good as it looks. Alpine’s preloaded, linkable subwoofer enclosures give you powerful performance with the unique Alpine Halo design and ProLink™.
The new 2nd generation Alpine R-Series subwoofers take bass performance to extreme levels, delivering thunderous, ground-pounding bass.
With Alpine’s enhanced sound performance, the Alpine R-Series subwoofers are highly accurate, creating a perfectly matched sound system to Alpine R-Series amplifiers and Alpine R-Series speakers – building an overall cohesive theme with its entire full-range Hi-RES Audio certified system. The Alpine R2-SB12V is designed for amplifier compatibility with 20hm loads.
UNIQUE PROLINK™ DESIGN
ALPINE HALO DESIGN
DEEPER BASS OUTPUT
A new Polypropylene/ceramic composite dust cap ensures rigidity while also providing incredible internal damping (Vibration Absorption) to smooth out the BASS response and produce tight BASS. This premium, unique material also has higher heat reliability that ensures non-stop BASS performance.
The 2nd Generation R-Series Subwoofers have retained Alpine HIGH AMPLITUDE MULTI-ROLL (HAMR) surround technology. This rubber surround allows the subwoofer cone to efficiently move air while staying cool, which also contributes to increased output from the subwoofers. This technology allows for 20mm of total cone excursion and motion that creates incredible accuracy from the subwoofer.
OPTIMISED SOUND PERFORMANCE
The ported enclosures feature an optimised vent and rounded internal port edges that maximise the output performance of the subwoofer, for deep reliable BASS. each enclosure is wired for optimised performance with Alpine's R-A75M R-series Mono Block Power Amplifier.
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 aluminium 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 aluminium 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.
