JL Audio, Car HiFi Lautsprecher, C2-350x (40 W, 9 cm)

Coaxial Speaker System: 3.5-inch (90 mm) Woofer, 0.75-inch (19 mm) Silk Dome Tweeter The Evolution C2 systems deliver sparkling high-frequency detail, smooth mid-range and powerful mid-bass, thanks to real silk dome tweeters and precision-engineered woofer designs. The C2-350x system features 3.5-inch (90 mm) woofers with mineral-filled polypropylene cones, long excursion capabilities and stamped steel frames. The woofer design benefits from JL Audio's vast woofer design experience and advanced modeling systems. Tweeters are coaxially mounted and built with 0.75-inch silk dome diaphragms that deliver smooth, extended response, on and off axis. The small size of the C2 tweeter minimizes tweeter protrusion, allowing C2 coaxials to fit behind most factory speaker grilles. Sold as a pair. Speaker grilles are not available for this speaker system. - Continuous Power Handling (RMS): 25 W - Recommended Amplifier Power (RMS): 10 - 40 W / Ch. - System Efficiency: 83 dB @ 1 W / 1 m - System Nominal Impedance: 4 Ω - System Frequency Response: 130 Hz - 22 KHz ± 3 dB.
