JL Audio C2-400X

The C2-400X coaxial speaker system from JL Audio is specifically designed to add depth and clarity to your music playback. As a 4-inch (10 cm) coaxial system, it offers a combination of woofer and silk dome tweeter. Equipped with a mineral-filled polypropylene cone and an embossed steel frame, the speaker provides sparkling treble details, smooth midrange and a powerful midrange. The C2-400X system is flexible in its installation, with cut-off mounting tabs for different configurations and included adapter plates for attachment to different speaker positions. The speaker grille with its attractive design is also included.

• Coaxial speaker system consisting of 4-inch (100 mm) woofer and 0.75-inch (19 mm) silk dome tweeter
  
• The Evolution C2 systems deliver sparkling high frequency 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 (100 mm) mid-bass drivers with mineral-filled polypropylene cones, long-throw capability and embossed steel frames. The woofer design benefits from JL Audio's extensive experience in woofer development and advanced modeling systems.
  
• Cuttable 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" silk dome diaphragms 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.
