The new Alpine r-series subwoofer is built off the highly esteemed type R Platform. With select key design and build improvements, the r-series subwoofer is able to output more of that deep bass extension and Control that the Type-R is known for. Type-r Subwoofers have been known for their power handling, clean output and deep bass excursion at a mid-line price. The r-series Subwoofers feature a kevlar-treated cone for durability. The combination of this cone with the santoprene surround allows the subwoofer to deliver 19mm of x-max, for incredible, hard-hitting bass. A new method of attaching the spider and cone to the voice Coil ensures not only rigidity throughout the motor structure but contributes to the Subwoofers increased accuracy.
