Alpine BassRev BRV-S65C 6.5″ 2-Way Component Speaker System
The Alpine BassRev BRV-S65C is a high-performance 6.5-inch 2-way component speaker system designed to deliver powerful mid-bass, precise control, and detailed high-frequency reproduction in a factory-replacement format. As part of Alpine’s all-new BassRev Series for 2025, the BRV-S65C brings advanced acoustic engineering to vehicles where space is limited but sound quality expectations are high.
Developed from Alpine’s decades-long expertise in car audio design, BassRev redefines what a 6.5-inch speaker can achieve by combining high-excursion bass capability with refined tonal accuracy. The BRV-S65C is ideal for drivers seeking a significant upgrade over factory speakers while retaining OEM fitment and appearance.
High-Excursion Bass Performance with HEDGE Surround Technology
At the core of the BRV-S65C is Alpine’s all-new HEDGE surround technology (High Excursion Design Gathered Edge). This advanced surround structure is engineered to dramatically increase woofer excursion, allowing the speaker to move more air and generate greater sound pressure in the critical 40Hz to 80Hz bass range.
With a maximum linear excursion peak of up to 28mm, the BRV-S65C delivers bass that is deep, punchy, and controlled. This enables the speaker to produce strong low-frequency impact without distortion, even at higher volume levels, making it an excellent solution for door-mounted applications where bass performance is traditionally limited.
Lightweight Polypropylene Woofer for Clean, Accurate Output
The 6.5-inch woofer features a lightweight yet highly rigid polypropylene cone designed to resist resonance and unwanted vibration. This material choice ensures the cone remains stable during high-excursion movement, allowing the speaker to reproduce bass and midrange frequencies with clarity and consistency.
By maintaining structural integrity under demanding conditions, the BRV-S65C delivers smooth, clean, and balanced sound reproduction across the frequency range, reducing distortion and improving overall sound quality compared to standard factory speakers.
High-Strength Motor Structure for Increased Output and Control
Supporting the woofer is a powerful motor assembly featuring a large Strontium Ferrite magnet and a substantial 40mm voice coil. This robust design increases magnetic force and driver control, allowing for higher output levels, improved efficiency, and greater bass impact.
The enhanced motor structure works seamlessly with the HEDGE surround to deliver louder, punchier sound while maintaining precision and long-term reliability, even when driven near the speaker’s limits.
Precision 1″ Soft Dome Tweeters with Neodymium Magnets
High frequencies are reproduced by 1-inch polyester soft dome tweeters engineered for smoothness, clarity, and detail. The low-mass polyester diaphragm accurately captures subtle transients and fine musical nuances, ensuring vocals, cymbals, and string instruments sound natural and well-defined.
Equipped with powerful Neodymium magnets, the tweeters offer excellent efficiency and control in a compact form factor. This results in clean, articulate high-frequency reproduction with a smooth upper harmonic range extending up to 20kHz, enhancing sound staging and overall realism.
OEM-Friendly Tweeter Fitment for Stealth Installations
The BRV-S65C tweeters are designed for seamless integration into factory locations. By removing the supplied housing and trim ring, the tweeter becomes compact enough to fit into many OEM tweeter mounts such as A-pillars, mirror triangles, or door sail panels.
This allows for a clean, factory-style appearance with minimal modification, making the BRV-S65C ideal for discreet audio upgrades that preserve the original interior design.
OPTIM™Sync DSP Compatibility for Enhanced Bass Performance
When paired with Alpine’s OPTIM™ DSP amplifiers, the BRV-S65C can take full advantage of Alpine’s proprietary OPTIM™Sync technology. This intelligent bass algorithm applies dynamic bass boost and pre-EQ tailored specifically for BassRev speakers.
OPTIM™Sync safely extends low-frequency performance, smooths tonal balance, and unlocks the full potential of the speakers, delivering a larger, more immersive soundstage than a conventional speaker setup alone.
