Description of R2-SB12V:

The next generation of sound performance is here with the new R-Series Halo Preloaded Subwoofers featuring the new R-Series “R2” subwoofers for more accurate and authoritative bass.

Features:

• Unique ProLink™ Design
  ProLink™ is unique to Alpine and allows you to link two R2-SB12V enclosures together using an optional KTX-H12 linking kit to create a dual subwoofer enclosure.
• Stand Out in the Crowd
  Drawing inspiration from the sleek, tapered lines and clean silver finish of the Alpine Halo display, the R2-SB12V shares the same unique, curved edges outlined by a silver trim and a metallic front baffle for a matching system aesthetic.
• Improved Performance
  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.
