  • Product Description
  • Vehicle Fitment
The JL Audio C7 range was designed with the sole intent to produce the finest-ever automotive component speakers. No detail, material or design element was overlooked in search of a pure audio experience displaying unsurpassed levels of resolution, precision and imaging. The result comprises a 6.5" component woofer, a 3.5" midrange and a 1" tweeter that all work together in perfect harmony.

Cone and Dust Cap
Vacuum-formed, mineral-filled polypropylene material offers excellent damping and low mass. The cone body features a gentle curvilinear profile to optimize response. A specially shaped dust cap attaches to the cone body and the voice coil former to improve high frequency behavior.

Suspension design
The moving assembly is suspended and damped via a large-diameter, linear profile spider formed from a Nomex/polycotton blend, and a positive-roll, rubber surround. The two combine to provide optimum damping without prematurely restricting the C7-650cw's outstanding excursion capability.

Motor Design
The C7-650cw employs a high-density magnetic circuit with a high-grade Y35 Strontium-ferrite magnet, and a specially machined, T-Yoke motor topology. Motor magnetics have been precisely optimized utilizing advanced FEA tools to reduce distortion and provide linear motor force throughout the driver's performance range.

A 32 mm (1.27 inch) diameter, overhung voice coil is employed, wound with copper wire onto a fiberglass voice coil former. The oversized voice coil offers extended power handling capability, minimizing thermal compression and distortion at higher listening levels. Chassis Design: A purpose-engineered cast alloy basket is employed, featuring thin spokes to maximize rear open area, and our Patented Elevated Frame Cooling technology.
