Alpine R2-W12D2

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.
