C7-100ct

1-inch (25 mm) Corundum Ceramic-Coated, Aluminum Dome Component Tweeter

C7 is the pinnacle of JL Audio automotive loudspeaker design, benefiting from our most advanced development tools and a complete commitment to precision manufacturing.

The C7-100ct component tweeter is designed to deliver unparalleled high-frequency performance. Utilizing a corundum ceramic-coated aluminum alloy diaphragm suspended via a treated silk, s-roll surround, it provides spectacularly detailed reproduction of treble frequencies with outstanding off-axis response. Distortion and non-linearities have been minimized through critical optimization of dynamic motor and suspension behaviors.

Passive crossover networks are not included with C7 drivers, as they are designed for active systems. Instead, we recommend a high-quality tuning DSP, such as the JL Audio TwK® 88 or D8, or a VXi amplifier with built-in DSP, with a dedicated amplifier channel for each C7 loudspeaker in the system. Precise setup of equalization, delay and crossover filters will ensure optimal in-vehicle performance.

Sold individually, with flush and surface mounting fixtures and hardware. One 15μF tweeter protection capacitor is also included.

The performance of every C7 driver is tested and verified, then assigned a unique serial number. Register your C7 loudspeaker online to receive a copy of its specific Acoustical Test Report.
