Description of R-W10D4:

The new R-Series subwoofers take a great platform to the next level. Although the R-Series subwoofers are new for 2017, they actually come from an impressive Alpine lineage – the Type-R subwoofers. Type-R subwoofers have been known for their power handling, clean output and deep bass excursion at a mid-line price. Using the highly successful Type-R subwoofers as a foundation, we applied various performance and hardware improvements to the design, essentially transforming them into the new R-Series subwoofers – The Next Evolution of Proven Performance. 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.
