JL Audio C2-650x
The JL Audio C2-650x is a 6.5″ (16.5 cm) two-way coaxial car speaker from the C2 series, combining real silk dome tweeter performance with smooth midrange and powerful midbass. The DMA-optimised woofer with mineral-filled polypropylene cone transitions smoothly to the coaxially mounted 0.75-inch pure silk dome tweeter, which delivers smooth, extended response on and off axis. A shallow 62 mm mounting depth and only 12 mm of tweeter protrusion let the C2-650x fit behind most factory grilles, and stylish JL Audio grilles are included.
Key Features
- DMA-Optimised Woofer: Proprietary motor, suspension and cone modelling systems reduce distortion, improve transient performance and deliver better bass response.
- Pure Silk Dome Tweeter: 19 mm (0.75″) silk dome diaphragm for smoother, cleaner sound with excellent off-axis response.
- Smooth Woofer Roll-Off: No harshness in the upper midrange; well-dampened cone and suspension minimise ringing.
