Alpine BassRev 4-Inch Component Speaker Set - BRV-S40C

Alpine BRV-S40C BassRev 4-Inch Component Speaker Set

Transform Your Drive with Alpine 4" BassRev Component Speakers
Experience the next evolution in car audio with the Alpine BRV-S40C 4" BassRev™ Component Speakers. Engineered for audiophiles seeking booming, distortion-free sound in a compact footprint, these speakers leverage advanced technology to deliver near 6.5" speaker presence—unlocking bigger, richer sound than their size suggests. Pair them with the Alpine OPTIM8® DSP/Amplifier and OPTIM™ Sync for BassRev-specific dynamic bass boost and pre-EQ that pushes the limits of low-end performance and brings out the true potential of your music.

Superior Active Design for Precision Sound
The BRV-S40C skips the passive crossover network, instead embracing an active configuration that lets each driver connect directly to its own amplifier channel. When combined with OPTIM8® and OPTIM™ Sync, you gain fine-tuned control over crossover points, EQ, and time alignment, ensuring every frequency is perfectly balanced. This sophisticated approach eradicates power loss, maximizes efficiency, and delivers consistently clear, authoritative sound.

Innovative Materials and Build Quality
Alpine's specialized lapel cone geometry boosts cone height and travel for extended linear excursion, providing robust bass without sacrificing midrange clarity. The durable polypropylene/mica cone and gun-metal topcoat offer long-lasting performance and a premium look, while the reinforced edged dust cap ensures stability—so every note stays sharp, even when you turn up the volume. Upgrade your vehicle's sound system and enjoy a fuller, more dynamic listening experience mile after mile.

Features

• 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 OPTIMT 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™ 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.
