Alpine BRV-S40 BassRev™ 4" 2-Way Speakers
Big Sound. Compact Design.
Experience powerful, full-range sound from a compact 4" speaker. The Alpine BRV-S40 BassRev™ 2-Way Coaxial Speakers are engineered to deliver the impact and richness of a much larger driver, bringing deeper bass, cleaner mids, and detailed highs to tight factory speaker locations.
Designed for vehicles where space is limited but sound quality matters, the BRV-S40 combines Alpine’s advanced BassRev™ technology with a high-excursion woofer design to produce impressive output without requiring a larger speaker footprint.
More Bass From a Smaller Speaker
The innovative HEDGE™ (High Excursion Design Gathered Edge) surround allows the woofer cone to move farther with better control, increasing low-end performance and delivering stronger, more dynamic sound. The unique lapel cone shape further improves excursion, helping the speaker produce fuller bass response and a more engaging listening experience.
Tuned for Maximum Performance
Pair the BRV-S40 with an Alpine OPTIM8® DSP amplifier featuring OPTIM™Sync Technology to unlock BassRev™ tuning. This advanced calibration applies vehicle-specific processing designed to enhance bass response and optimize the speaker’s performance for a bigger, more immersive sound.
Clear, Detailed Audio
Built with a rigid polypropylene and mica woofer cone, the BRV-S40 delivers accurate response, controlled movement, and clean midrange performance. The coaxial 1" tweeter adds crisp high-frequency detail, helping vocals and instruments sound natural and balanced across your favorite music.
Premium Construction. OEM-Friendly Fit.
The BRV-S40 features a durable gun-metal finish, ferrite magnet motor structure, and a shallow mounting profile designed to fit factory locations where installation depth is limited. It’s an ideal upgrade for improving your vehicle’s sound while maintaining a clean, factory-style installation.
