Alpine BRV-S40C BassRev 4" Coaxial 2-Way Component Speaker System (BRVS40C)

Alpine BRV-S40C BassRev 4" Coaxial 2-Way Component Speaker System (BRVS40C)

If you’ve been craving a compact speaker system that packs a punch, the Alpine BRV-S40C is your new favorite upgrade. This 4" BassRev™ Component Speaker Set is engineered to sound way bigger than it looks—bringing a level of power, precision, and clarity that’s hard to believe comes from such a small footprint.

Big Sound, Compact Design

Don’t let the size fool you. The Alpine BRV-S40C may be just 4 inches, but it delivers sound that rivals much larger speakers. Thanks to Alpine’s BassRev™ technology, you get a wide, open soundstage with tight mids, crisp highs, and surprisingly deep lows. It’s like giving your car the sound system of a concert hall—without giving up space.

Separation That Brings Clarity

Each driver in the BRV-S40C does exactly what it’s meant to do. The 4" woofer handles the warmth and foundation, while the ¾" cloth-dome tweeter takes care of the sparkle and detail. Together, they create a balanced, layered sound where every instrument and vocal sits perfectly in place. The result? Music that feels alive, open, and natural at any volume.

HEDGE™ Surround: The Secret to Bigger Bass

The magic behind the BRV-S40C lies in Alpine’s HEDGE™ (High Excursion Design Gathered Edge) surround. Think of it like a performance suspension system for your speaker cone. This design allows the woofer to move farther, faster, and more smoothly—translating into a stronger low-end presence and fuller mids. You get that big-speaker energy in a compact 4" body that hits like a 6.5" driver.

Maximize Your Sound with OPTIM™ Sync Technology

When paired with Alpine’s OPTIM8® DSP/Amplifier, the BRV-S40C becomes an entirely different beast. Using OPTIM™ Sync Technology, Alpine’s proprietary BassRev tuning applies a smart bass boost and pre-EQ, unlocking every bit of performance potential these speakers have. This pairing enhances low-end response, balances tone, and pushes clarity to a new level. It’s the perfect harmony between precision engineering and advanced tuning.

Built for Active Systems

The BRV-S40C is designed for active setups—meaning each driver gets its own amplifier channel and crossover. That means more power, more control, and more clarity. With no passive components to sap your signal, the sound stays pure and accurate. Whether you’re tuning for punchy bass, smooth mids, or sparkling highs, active control lets you shape your system exactly the way you want it.

Durable and Refined Construction

Alpine didn’t cut corners with materials either. The woofer’s polypropylene and mica cone delivers a rigid yet responsive structure for clean bass and natural mids. Its ferrite magnet motor ensures stable performance under pressure, while the gun-metal coating adds a sleek, premium look that resists wear and tear. It’s a combination of performance and polish—built to sound as good as it looks.
