Product Description

JL Audio C7-350cm 3.5″ Component Midrange Car Speaker – #99758

JL Audio C7-350cm component midrange is designed to operate in a 3-way system, with a woofer and tweeter. Conceived and purpose-built from the ground up, it offers exceptional transient response and outstanding linearity, resulting in unsurpassed clarity and natural mid-range reproduction. 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, and 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.

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.

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.

Power Handling

JL Audio lists two power figures for this woofer; 100 watts continuous power handling and recommended amp power 50-150 watts RMS.
