R-W12D4 - 12′′ (30 cm) Subwoofers (4Ω + 4Ω)

£229⁰⁰

Alpine is proud to announce the introduction of the new R-Series Subwoofer lineup that 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.

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.
