THE ULTIMATE IN AUTOMOTIVE AUDIO FIDELITY
Built from the ground up to exceed the highest standards, JL Audio C7 speakers make no compromises in delivering a pure and precise audio experience. A 3.5-inch midrange speaker offers exceptional transient response and outstanding linearity, resulting in unsurpassed clarity and natural midrange reproduction.
ELEVATED FRAME COOLING
The patented Elevated Frame Cooling™ design by JL Audio delivers cool air through slots directly above the top plate to the voice coil of the speaker. This enhances power handling as well as sound quality by minimizing dynamic parameter shifts and power compression.
GRILLE OPTIONS
C7-350cm speakers each include a cast-alloy grille tray, one fine mesh steel grille insert and one spiral steel grille insert.
FINITE ELEMENT ANALYSIS (FEA) MOLDED DRIVERS
C7 design solutions were created and refined by using powerful mechanical and FEA modeling systems from JL Audio, including their proprietary dynamic motor analysis software. These studies led to innovative motor and suspension solutions, which were key to meeting the C7 design goals for smooth off-axis response, dynamic stability and low distortion.
