Overview: C2 Speaker Systems

Real silk dome performance with smooth mid-range and powerful mid-bass capabilities.

Utilizing advanced technologies, C2 speaker systems deliver an impressive audio performance solution and value. C2 component and coaxial woofers benefit from JL Audio's vast woofer design experience and advanced modeling techniques. C2 tweeters incorporate silk dome diaphragms to deliver smooth high-frequency transitions, on and off axis. Built in a compact chassis with premium components, C2 crossovers offer three levels of tweeter attentuation, plus tweeter protection. Return to C2 speaker systems.

Silk Dome Tweeter LOGO

Silk Dome Tweeter

Silk is a natural material that is light and fast moving with inherently good characteristics as a tweeter diaphragm. Silk exhibits excellent damping properties, which reduces ringing and resonances in the tweeter’s passband, leading to a smooth, pleasing high-frequency character free from unnatural sibilance or exaggerated brightness.
