• C2 4" (100 mm) coaxial speaker system

Features:

• Coaxial speaker system consisting of 4-inch (100 mm) woofer and 0.75-inch (19 mm) silk dome tweeter
  
• Evolution C2 systems deliver sparkling tweeter detail, smooth midrange and a powerful midrange thanks to true silk dome tweeters and precision-engineered woofer designs.
  
• The C2-400x system features 4-inch (100mm) woofers with mineral-filled polypropylene cone, long excursion capability and stamped steel frame. The woofer design benefits from JL Audio's vast experience in woofer design and advanced modeling systems.
  
• Cutaway mounting tabs on the woofer frame allow the C2-400x to be installed in four-hole or two-hole configurations.
• Also included are injection molded adapter plates that allow the C2-400x speakers to be mounted in a 4 x 6 (100 x 150 mm) speaker position.
  
• The tweeters are coaxially mounted and constructed with 0.75-inch silk dome cones that deliver a smooth, extended response on and off axis. The small size of the C2 tweeter minimizes tweeter protrusion, allowing C2 coaxial speakers to fit behind most factory speaker grilles.
