Next-Generation 8-inch R-Series Subwoofer with Dual 4-Ohm Voice Coils

Key Features

  • Dual Voice Coil (DVC) Subwoofers with Configuration Jumpers
  • Polyproplene/Ceramic Composite Dust Cap

  • Twist-Lock Grille Mount System
  • High-Amplitude Multi-Roll (H.A.M.R) Surround

Features

  • Next Gen Sound Performance
    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.
  • New Motor Structure
    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.
  • Additional Reliability
    A new polypropylene/ceramic composite dust cap ensures rigidity while also providing incredible internal damping (vibration absoption) to smooth out the bass response and reproduce tight bass. This premium, unique material also has higher heat reliability that ensures non-stop bass performance.
  • Flexible Application
    The 2nd-Gen 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 R2-W8D4 is compatible with the KTE-8G Grille System (sold separately).
  • Increased Accuracy
    The 2nd Gen R-Series Subwoofer contain Alpine's Hugh Amplitude Mult-Roll (HAMR) Surround Technology. This rubber surround allows the subwoofer cone to efficiently move air while staying cool. This technology allows for 12mm of total cone excursion and motion that creates incredible accuracy from the subwoofer.
