Alpine’s HEDGE™ surround on the BassRev™ BRV-S65 acts like precision suspension for your woofer. This innovative design allows the 6.5" cone to move up to 30% farther than traditional surrounds while maintaining exceptional control and linearity. The result is stronger low-end output, deeper bass extension, and the impact of a larger driver—all while preserving smooth midrange clarity and natural vocal presence. Experience subwoofer-sized bass performance from a compact 6.5" coaxial speaker.
Unlike traditional coaxials with a raised center post, the BassRev™ BRV-S65 features an inlaid tweeter mounted directly into the cone. This placement brings the woofer and tweeter closer to the same acoustic center, ensuring their sound waves reach your ears in perfect sync. The result is a seamless transition between highs and mids, delivering smoother treble, a wider sweet spot, and precise, well-balanced imaging across every seat — making this coaxial sound remarkably like a true component system.


The BassRev™ BRV-S65 delivers outstanding performance on its own, but when paired with Alpine’s OPTIM8 DSP/Amplifier using OPTIM Sync™, it transforms into a truly remarkable system. OPTIM Sync applies BassRev-specific tuning, featuring dynamic bass enhancement and precisely tailored pre-EQ to safely extend low-end output and refine tonal balance. The result is richer, deeper, and more natural sound that feels larger than life—delivering an immersive listening experience no standalone speaker can match.
