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

The Alpine BRV-S40C is a compact 4" speaker system engineered to deliver surprisingly big, precise sound. With BassRev™ technology, it produces a wide, open soundstage with tight mids, crisp highs, and deep lows—offering concert-hall quality in a small footprint.

Balanced, Layered Sound

The 4" woofer provides warmth and foundation, while the ¾" cloth-dome tweeter adds clarity and detail. Together, they create a natural, alive sound at any volume.

HEDGE™ Surround for Bigger Bass

Alpine’s High Excursion Design Gathered Edge (HEDGE™) allows the woofer to move farther and smoother, producing stronger lows and fuller mids, giving 4" speakers the energy of a 6.5" driver.

OPTIM™ Sync Technology

Paired with Alpine’s OPTIM8® DSP/Amplifier, the BRV-S40C uses smart BassRev tuning to enhance low-end response, balance tone, and improve clarity.

Designed for Active Systems

Each driver is powered separately, providing more control, precision, and pure sound. This active setup allows exact tuning for bass, mids, and highs.

Durable, Refined Construction

The polypropylene/mica woofer cone ensures clean bass and natural mids, while the ferrite magnet provides stable performance. A gun-metal finish adds sleek durability.
