Woofers: The JL Audio Evolution C2-400x coaxial speakers feature
a 4" injection-molded, mica-filled polypropylene cone woofer with a butyl rubber
surround, a 1.0" 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: The Evolution C2-400x coaxial speakers feature
a 0.75" 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: The Evolution C2-400x coaxial speakers include
front-loading protective grilles with a striking design that combines black
steel mesh with 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 Evolution C2-400x coaxial speakers can be mounted
in most standard 4.0" 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 lists two power figures in the
manual; 35 watts continuous power handling and recommended amp power 10-50
watts RMS. We've listed the RMS power recommendation in the specs table.
