Alpine BRV-S40C BassRev™ 4" Component Speaker System

High-res audio certified

The Alpine BRV-S4C 4" component speakers are an excellent way to add life to your sound. In fact, they're Hi-Res Audio Certified by the Japan Audio Society (JAS). These component speakers include a pair of mid-bass woofers and a pair of 3/4" tweeters that Alpine has designed and tested to maximize the Optim DSP output from select Alpine amplifiers. The 4" mid-bass driver has a HEDGE (High Excursion Design Gathered Edge) surround, a new design from Alpine for a multi-roll surround with a corrugated design, so the stress is spread across the ribs you see in the image below, acting like an expansion joint that lets the cone travel without stretching the surround too much. This design is usually found on high-excursion subwoofers, where a speaker needs long travel and great control.

Built with a blend of polypropylene and mica for responsive sound and durability.

About Alpine

Alpine's history in the automotive industry runs deep. Over the years, Alpine has teamed up with heavy-hitter automakers like BMW, and Mercedes-Benz to crank out custom audio setups that are as sharp as the cars they go into. Experience the sound of Alpine in your car, no matter the make.

Installation note: You may need a pair of our universal backstraps to install the tweeters in factory dash openings.
