About the JL Audio C7-650CW: 6.5" 175 W RMS C7-Series Component Woofer
6.5" (165 mm) Component Woofer, including Grille. C7-Series 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 Midrange is capable of operating in a 2 way system, including a Midrange and tweeter, or through 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 Midbass and pure, precise, Midrange performance. Distortion and non linearities have been minimized through critical optimization of dynamic motor and suspension behaviours.
Passive crossover networks do not include C7-Series drivers, as they are designed for active systems. Instead, we recommend a high quality tuning DSP, such as the JL Audio TWK 88 / D8, or a VXI amplifier through built in DSP, through a dedicated amplifier channel for each C7-Series loudspeaker in the system. Precise setup of equalization, delay and crossover filters will ensure optimal in vehicle performance.
Design notes:
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 behaviour.
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 through a high grade, Y 35 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 (1.3") diameter, overhung voice coil is employed, wound through 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, and our patented elevated frame cooling technology.
Design bandwidth:
Including 48 dB / octave filters: 500 hz - 5 kHz; 24 dB / octave filters: 60 hz - 5 kHz; 12 dB / octave filters: 70 hz - 5 kHz
Built through global components. Sold individually, through a cast alloy grille tray, 1 fine mesh and spiral steel grille insert.
The performance of every C7-Series driver is tested and verified, then assigned a unique serial number. Register your C7-Series loudspeaker online to receive a copy of its specific acoustical test report.
