Loud. Clean. Long.

Alpine Type-R subwoofers play loud, clean, and long. The Type-R's are designed from HAMR Engineering, Alpine's exclusive subwoofer solution for cooler operation, longer life, and tight, accurate bass. The main philosophy behind HAMR Engineering is to ensure the ultimate sound quality and performance through the use of highly advanced materials and patented design technologies such as magnetic, structural finite element analysis, and a 3rd generation CRC motor structure. The Type-R subwoofer features an ultra long linear excursion for dynamic, realistic sound. Exclusive cooling technologies contribute to huge power handling capabilities. You can depend on the Type-R to compliment your system with deep, accurate bass.
