JL Audio C2-650X Evolution Series Coaxial Speakers

The Evolution C2 systems deliver exceptional sound quality, offering sparkling high-frequency detail, smooth midrange, and powerful mid-bass. This is achieved through real silk dome tweeters and precision-engineered woofer designs.

The C2-650x system features 6.5-inch (165 mm) woofers with mineral-filled polypropylene cones, long excursion capabilities, and stamped steel frames. These woofers are crafted using JL Audio’s extensive expertise and advanced modeling systems, ensuring outstanding performance. The 6.5-inch format is designed to fit directly into many vehicles, with multiple mounting patterns on the woofer frame for easy installation.

The 0.75-inch silk dome tweeters are coaxially mounted to deliver smooth, extended response both on and off axis. Their compact design minimizes protrusion, enabling the C2 coaxial speakers to fit seamlessly behind most factory speaker grilles.

Each system includes woofer grilles, featuring a black grille tray with satin silver accents and a black steel mesh grille adorned with an electroformed JL Audio logo.
