JL AUDIO (C2-600CW) 6.0-INCH (150MM) COMPONENT WOOFER (EACH) FEATURES: 6-inch (150 mm) 2-Way Component Woofer (Single) The Evolution C2 speakers deliver smooth mid-range and powerful mid-bass thanks to long linear excursion woofer designs. The C2-600cw is a 6-inch (150 mm) component woofer with mineral-filled polypropylene cone, long excursion capabilities and a stamped steel frame. The woofer design benefits from JL Audio's vast woofer design experience and advanced modeling systems. The 6-inch (150 mm) format is a direct fit in many Japanese vehicles where a full-size 6.5-inch speaker (165 mm) will not fit without modification. Multiple mounting patterns are provided on the woofer frame for easy installation into most vehicles that accept a 6-inch (150 mm) speaker. A woofer grille is included, consisting of a black grille tray with satin silver accent and a black steel mesh grille with an electroformed JL Audio logo.
