JL Audio C2-400x

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 C2-400x 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.

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.

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.

Sounds Great

Just put in a pair of the JL Audio C2-400X into the dash of my 2000 Porsche Boxster S. and they sound great! I cut the old speakers out to make a mounting bracket. And that work. Overall Sonic Electronix was easy to order from and the speakers sound great.

Quality Item

After fitting a JL Audio amp & speakers to my Jaguar XKE I added the JL C2 400x to the front console area which is limited in space, the JL's perform beyond their size & price! Sonic Electronix dispatched quickly & efficiently, good service, would definitely use Sonic again
