JL Audio's Evolution C2 Series speakers
JL Audio's Evolution C2 Series speakers
JL Audio's Evolution C2 Series speakers bring precision sound to your vehicle. They'll reproduce subtle elements of your music like delicate woodwinds or soprano vocals, then turn on a dime to deliver the deep thrum of the bass or thunder of the drums.
Silk tweeter delivers smooth highs
The C2-400X 4" speakers feature rugged polypropylene cones with rubber surrounds that can handle plenty of power without distortion, so you get full-bodied tones. The 3/4" silk dome tweeters serve up smooth-sounding high frequencies that won't tax your ears, adding a satisfying dose of realism to your soundstage. Built-in crossovers ensure that the tweeters and woofers reproduce only the frequencies that they were designed to handle, so your tunes play smoothly across the whole musical spectrum. JL Audio includes a pair of grilles for custom installations, and a set of adapters that allow you to install these speakers in 4"x6" openings.

Woofers: The JL Audio Evolution C2-400x speakers feature a 4" injection-molded, mica-filled polypropylene cone woofer with a butyl rubber surround, a 1" voice coil on a Kapton Former, a symmetrical roll spider and a Ferrite magnet. These carefully engineered cones deliver the right combination of stiffness, damping, and off-axis response. The speaker also provides good mid-bass, thanks to its mechanical clearance, optimized suspension and balanced motor design.
Tweeters: Each coaxial speaker features a ¾" silk dome, ferrofluid-cooled tweeter with a damping neodymium magnet. The edge-driven silk dome tweeter is smooth, detailed (on or off axis), and provides great overall performance. Silk is lightweight and great for high frequency extension and efficiency. It is also designed for durability in the extreme automotive environment.
Grilles: Front-loading protective grilles are included, with black steel mesh and satin silver accents. Electroformed logo nameplates can be positioned on the grilles or elsewhere in the vehicle, according to the needs of the installation.
Mounting: The speakers can be mounted in most standard 4" speaker applications. They also include 4x6 adapter plates for mounting in 4x6 speaker applications.
Removable Mounting Tabs: Most 4" factory speakers use four mounting screws. However, in some vehicles, only two mounting holes are used. In these cases, you can bend any unnecessary mounting tabs on the C2-400x speakers until they break off. The tabs are scored specifically for this purpose. Care should be taken in handling the speaker because the broken edges may be sharp.
Power Handling: JL Audio publishes several power specifications for this speaker, 35 watts continuous power handling (RMS), 105 watts peak music power, and 10-50 watts recommended amplifier power (RMS). We've listed the conservative combination of 10-35 watts RMS in the specs table.
