About The Product
Separation Brings Clarity
As a true 2-way component set, the Alpine BassRevâ„¢ BRV-S40C lets each driver focus on what it does best. The 4″ woofer provides foundation and warmth while the 3/4″ cloth-dome tweeter brings the detail. With each driver working in its ideal range, you get a wide, precise soundstage with clear vocals, natural cymbals, and clean separation between instruments—so your music feels open, layered, and engaging at any volume, from a compact 4″ footprint.
Big-Speaker Energy
Alpine’s HEDGEâ„¢ surround on BassRevâ„¢ speakers acts like performance suspension for your woofer. On the BRV-S40C, this unique surround lets the 4″ cone move farther with control, so more power becomes real, room-filling impact—not wasted motion. That extra, linear movement translates to stronger low-end presence and fuller mids, giving the BRV-S40C the impact you expect from a larger 6.5″ driver while preserving smooth mids and clear vocals. The result is big-speaker feel from a compact 4″ component.
