Alpine R2-SB10V Single Type R2 10-in Subwoofer in Vented Enclosure

The new R2-Series subwoofers now feature larger, double-stacked magnets that contribute more motor force for deeper bass and tighter bass control compared to the previous generation. ProLink™ is unique to Alpine and allows you to link two R2-SB10V enclosures together using an optional KTX-H10 Linking Kit (sold separately) to create a dual subwoofer-enclosure. Drawing inspiration from the sleek, tapered lines and clean silver finish of the Alpine Halo Display, the R2-SB10V shares the same unique, curved edges outlined by a silver trim and a metallic front baffle for a matching system aesthetic. The ported enclosure design features an optimized vent and rounded internal port edges that maximize the output performance of the subwoofer. Made from 3/4" medium density fiberboard (MDF) with internal edge bracing, the R2-SB10V is sturdy with a rugged, yet stylish black carpet cover and brushed aluminum finish on the metallic front baffle. The R2-SB10V includes a preloaded R2-Series R2-W10D4 10" subwoofer that's turned to 36Hz for optimized performance with Alpine's R-Series sound system line. Dual 4Ω voice coils are wired in parallel for a 2Ω load that's compatible with the R2-Series R2-A75M Mono Power Amplifier. Gold-plated binding post terminals allow for speaker wire, ring terminal, or quick disconnect banana plug connections from your amplifier's output.
