The 2nd-Gen R-Series Subwoofers by Alpine redefine sound performance, delivering unparalleled bass with enhanced precision. The R2-W12D4, a 12-inch subwoofer with Dual 4-Ohm Voice Coils, embodies this advancement with a newly engineered motor structure. Double-stacked magnets provide greater motor force, ensuring deeper, tighter bass control. An integrated Faraday ring reduces distortion for cleaner sound, while the durable Kevlar-treated cone withstands high-volume output without compromising performance. Built for reliability, the R2-W12D4 features a polypropylene/ceramic composite dust cap that offers superior rigidity and internal damping, minimizing vibrations for smooth bass response. This high-quality material also excels in heat resistance, guaranteeing consistent, uninterrupted performance. Flexibility is key with its Dual Voice Coil (DVC) design and EZ-Change twist-lock grille mounting system, allowing quick grille installation without screws and adaptable applications. Alpine’s High Amplitude Multi-Roll (HAMR) Surround Technology enables the subwoofer’s cone to move air efficiently, supporting 20mm of total cone excursion for remarkable sound accuracy. With these innovations, the 2nd-Gen R-Series Subwoofers deliver a listening experience that is powerful, precise, and reliable—perfect for audiophiles seeking the next level of bass performance.
Next-Generation 12-inch R-Series Subwoofer with Dual 4-Ohm Voice Coils
The next generation of sound performance is here with the 2nd-Gen R-Series Subwoofers featuring a larger motor structure for more accurate and authoritative bass.
Since the Type R platform, Alpine’s R-Series sound system family has been known for its incredible output and reliable performance. Now Alpine introduces the next-generation of sound performance with the 2nd-Gen R-Series Subwoofers with even more bass output.
The 2nd-Gen R-Series Subwoofers now feature larger, double-stacked magnets that contribute more motor force for deeper bass and tighter bass control from the subwoofer cone compared to the previous generation. An integrated Faraday ring minimizes distortion for cleaner bass output. A Kevlar-treated cone ensures durability in the subwoofer for reliable performance, even at high volumes.
