Experience big-speaker energy from a compact 4-inch coaxial with the Alpine BRV-S40 BassRev speakers. Engineered with a HEDGE surround and a unique lapel cone, they deliver controlled excursion for stronger low-end presence and fuller mids that rival a larger 6.5-inch driver.

Pair them with an Alpine OPTIM8 DSP amplifier using OPTIM Sync technology to unlock dynamic bass boost and tailored EQ, safely extending performance for near-6.5-inch presence. The rigid polypropylene and mica cone with a gun-metal finish ensures clean, punchy sound and lasting durability on every drive.
