Alpine R2-W12D4
R-Series 12” Subwoofer (4Ω + 4Ω)
The new R-Series subwoofers now feature larger, double-stacked magnets that contribute more motor force for deeper bass and tighter bass control. 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. A new Polypropylene/ceramic composite dust cap ensures rigidity while also providing incredible internal damping. The new R-Series subwoofers contain a Dual Voice Coil (DVC) with easy configuration jumpers that allow for flexible applications. A new “EZ-Change” twist-lock grille mounting system makes it easy to install and remove an optional grille without mounting screws for added protection to the cone. The new R-Series subwoofers contain Alpine’s High Amplitude Multi-Roll (HAMR) Surround Technology. The R-Series subwoofers are High-Resolution Audio Compliant. Rated at 750W RMS (2250 peak power handling), the R-Series subwoofers will provide deep bass output.
