About: Alpine BassRev BRV-S40C 4" Mid-range Component Speakers with Tweeters
Compact size, big-speaker feel - the Alpine BRV-S40C 4" BassRev™ Component Speakers are designed to deliver larger-than-life sound.
SEPARATION BRINGS CLARITY
As a true 2-way component set, the Alpine BassRev™ BRV-S40C lets each driver focus on what it does best. The 4" woofer provides foundation and warmth while the 3/4" cloth-dome tweeter brings the detail. With each driver working in its ideal range, you get a wide, precise soundstage with clear vocals, natural cymbals, and clean separation between instruments—so your music feels open, layered, and engaging at any volume, from a compact 4" footprint.
BIG-SPEAKER ENERGY
Alpine’s HEDGE™ surround on BassRev speakers acts like performance suspension for your woofer. On the BRV-S40C, this unique surround lets the 4" cone move farther with control, so more power becomes real, room-filling impact—not wasted motion. That extra, linear movement translates to stronger low-end presence and fuller mids, giving BRV-S40C the impact you expect from a larger 6.5" driver while preserving smooth mids and clear vocals. The result is big-speaker feel from a compact 4" component.
MAX IMPACT WITH OPTIM™
The BRV-S40C is impressive on its own, but the real magic happens when you pair it with Alpine's OPTIM8® DSP/Amplifier using OPTIM™M Sync, our BassRev-specific tuning. OPTIM™ Sync intelligently applies dynamic bass boost and pre-EQ tailored to these drivers, safely extending low-end performance and smoothing tone to unlock their full potential. The result is bigger-than-size sound--a 4" set that plays with near-6.5" presence a speaker alone just can't match.
BUILT FOR ACTIVE TUNING
BassRev™M components are designed to run active, so there's no passive network in the box by design. When paired with Alpine OPTIM8® using OPTIM™ Sync, each driver gets its own amplifier channel and crossover for cleaner, more accurate sound. You gain precise control of crossover points, slopes, EQ, and time alignment, with no power lost in passive parts. The result is greater efficiency, consistency, and clarity than traditional passive component sets.
FULLER, MORE DYNAMIC MUSIC
The specialized lapel cone shape increases cone height and travel, giving the woofer more linear excursion than traditional designs. That extra, well-controlled movement delivers stronger low-end output while keeping the midrange clean and focused. Music feels fuller and more dynamic, and voices and instruments stay clear even at higher volumes.
RIGID, REFINED BUILD
Crafted to perform and last, the polypropylene/mica cone holds its shape for tight bass and natural mids. A durable gun-metal topcoat adds a premium finish and shrugs off daily wear. The edged dust cap reinforces the cone so playback stays stable and composed as the volume climbs. Together, these materials deliver clear, punchy sound with a refined finish you'll appreciate on every drive.
