C7-650cw

6.5" (165 mm) Component Woofer

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 C7-650cw component woofer is capable of operating in a 3-way system, with a midrange and tweeter, or with only a tweeter in a 2-way configuration. Engineered from the ground up, it has exceptional linear excursion capability and outstanding linearity, resulting in solid mid-bass and pure, precise, mid-range performance. 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 a cast-alloy grille tray, one fine mesh steel grille insert and one spiral steel grille insert.

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.
