- Peak Power Handling: 2250 watts (The maximum amount of power an electronic device, like a speaker, can handle without damage. This refers to short bursts of power, while root mean square (RMS) power handling indicates the amount of continuous power a device can sustain. Higher levels of distortion can also occur at peak power levels when the device is powered beyond its recommended usage.)

Alpine's Halo Series subwoofer enclosures make it easy to add more bass to your system. The pre-loaded R-Series 12" dual voice coil subwoofer provides plenty of bass on its own, but when you want even more, the optional linking kit can connect two together for double the impact.
- ProLink connection: ProLink is unique to Alpine and allows you to link two R2-SB12V enclosures together using an optional KTX-H12 Linking Kit (sold separately) to create a dual subwoofer-enclosure.
- Halo display inspired: Drawing inspiration from the sleek, tapered lines and clean silver finish of the Alpine Halo Display, the R2-SB12V shares the same unique, curved edges outlined by a silver trim and a metallic front baffle for a matching system aesthetic.
- Ported enclosure design: Features an optimized vent and rounded internal port edges that maximize the output performance of the subwoofer
- Sturdy, yet rugged: Made from 3/4" medium density fiberboard (MDF) with internal edge bracing, the R2-SB12V is sturdy with a rugged, yet stylish black carpet cover and brushed aluminum finish on the metallic front baffle.
- Preloaded R2-Series R2-W12D4: Includes a preloaded R2-Series R2-W12D4 12" subwoofer that's turned to 35Hz for optimized performance with Alpine's R2-Series sound system line.
- Compatible with the R2-Series R2-A75M Mono Power Amplifier: Dual 4 ohm voice coils are wired in parallel for a 2 ohm load
- Flexible application: The 2nd-Gen R-Series subwoofers contain a Dual Voice Coil (DVC) with easy configuration jumpers that allow for flexible applications
- Next Gen sound performance: The new 2nd-Gen R-Series subwoofers now have even more bass output than their predecessors
- New motor structure: Now feature larger, double stacked magnets for deeper bass and tighter bass control from the subwoofer cone compared to the previous generation
- Cleaner bass output: Integrated Faraday ring minimizes distortion
- EZ-Change twist-lock grille mount system: Makes it easy to install and remove optional grille without mounting screws
- Increased Accuracy: The 2nd-Gen R-Series subwoofers contain Alpine's High Amplitude Multi-Roll (HAMR) surround technology that creates incredible accuracy from the subwoofer
- Kevlar-treated cone: Kevlar adds strength and tear resistance to the woofer cone while maintaining the benefits of a pulp cone design
