C7 3.5″ (90mm) Component Mid – Single

£369.99

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 concave dust cap further improves high frequency behavior.
Suspension design
The moving assembly is suspended and damped via a 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 excursion.
Motor Design
The C7-350cm employs a high-density magnetic circuit with a high-grade, neodymium magnet, and a specially machined, U-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 36 mm (1.42 inch) diameter, overhung voice coil is employed, wound with copper-clad aluminum 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.
