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. Breakaway mounting tabs on the woofer frame allow the C2-400x to be installed in four-hole or two-hole configurations. Injection-Molded adaptor plates are also included to allow mounting of the C2-400x speakers into a 4 x 6 (100 x 150 mm) speaker location.
Vast woofer design
The C2-400x system features 4-inch (100 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.
Silk Dome Tweeter
Silk is a natural material with inherently good characteristics as a tweeter diaphragm. In addition to being very light in weight, 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. Compared to a harder material dome, a silk tweeter does not exhibit as much ultra-high frequency extension, but is preferred by many audiophiles for its overall balance.

Used them to replace the speakers in my audi quattro, they are night and day better than the old speakers and are better than my Pioneer 4" speakers but I feel that there is still a bit of harshness in some of the higher frequencies. A better eq from the radio or an external crossover may help but ive decided to switch to a component set of speakers. Overall still a good speaker just not quite the sound im looking for
180 degrees better than my old stereo had them replaced hust the other day
