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

Havent found a con yet. Paired with Alpine amps these subs will out perform higher priced subs on the market and never get warm.
