Alpine BRV-S40C BassRev™ 4" 2-Way Component Speaker System
Compact Design. Full-Size Performance.
Experience a new level of sound from a compact 4" component speaker system. The Alpine BRV-S40C BassRev™ delivers the clarity, detail, and impact of a larger speaker with a space-saving design engineered for premium in-vehicle audio upgrades.
Featuring a dedicated 4" woofer and separate 3/4" tweeter, the BRV-S40C creates a wider, more precise soundstage by allowing each driver to focus on its ideal frequency range. Vocals sound more natural, instruments feel more separated, and every track gains a more immersive presence.
Big Sound From a Small Footprint
The BRV-S40C is engineered to deliver impressive midrange and low-frequency performance despite its compact size. Alpine’s HEDGE™ (High Excursion Design Gathered Edge) surround technology allows the woofer cone to move farther with greater control, increasing output and extending bass response.
The unique lapel cone design improves cone movement and rigidity, helping produce stronger mid-bass impact while maintaining smooth, accurate playback.
True Component Sound Separation
Unlike coaxial designs, the BRV-S40C separates the woofer and tweeter for improved placement flexibility and sound staging. The 4" woofer provides rich midrange and punchy low-end response, while the 3/4" cloth-dome tweeter delivers crisp, detailed highs with a natural presentation.
The result is a cleaner, more balanced listening experience where vocals, percussion, and instruments remain distinct.
Tuned for Alpine OPTIM™ Performance
The BRV-S40C is designed to pair with Alpine OPTIM8® DSP/amplifier technology using OPTIM™ Sync. When integrated with OPTIM8®, BassRev-specific tuning applies advanced processing designed to enhance bass response, refine tonal balance, and maximize the performance of the speaker system.
For active installations, the BRV-S40C allows precise control over crossover points, EQ, and time alignment when paired with compatible DSP amplification.
Premium Materials. Engineered Reliability.
Built with a polypropylene and mica woofer cone, the BRV-S40C provides excellent rigidity for cleaner response and reduced distortion. A durable rubber HEDGE™ surround supports controlled cone movement, while the gun-metal finish adds a premium appearance to match its performance-focused design.
