Product Description

Alpine’s new 2nd generation R-Series Subwoofers feature enhanced sound performance in an exciting new aesthetic. With a larger motor structure featuring double-stacked neodymium magnets and an integrated faraday-ring results in a deeper, cleaner and tighter bass while the all-new Kevlar-treated cone ensures this extra performance is reliable – even at higher volumes.

The new EZ-Change twist-lock grille mounting system makes subwoofer installation easier than ever-before. The optional grille (KTE-12G), exudes a tough look with the benefit of added protection.

Quality and Performance unrivalled in the industry, Alpine’s new 2nd Generation R-Series continues to be the benchmark in sound quality for the audio enthusiast.
