Features of R2-W8D4:

• New Motor Structure
  The new R-Series subwoofers now feature larger . double-stacked magnets that contribute more motor force for deeper bass and tighter bass control compared to the previous generation.
• Oversized Dust Cap
  The new hybrid poly ceramic composite dust cap ensures rigidity while also providing incredible internal damping (vibration absorption) to smooth out the bass response and reproduce tight bass.
• Increased Accuracy
  Alpine's High Amplitude Multi-Roll (HAMR) Surround Technology allows the cone to efficiently move air while staying cool resulting in incredible accuracy from the subwoofer.
