• C1 4" (100 mm) coaxial speaker system
• The 10cm coax top seller from JL Audio!

Features:

• Coaxial speaker system with 4-inch (100mm) woofer and 0.75-inch (19mm) aluminum dome tweeter.
  
• The C1 speakers deliver real substance and great audio performance in a format designed to be easily mounted behind factory grilles.
  
• For ease of installation, cutaway mounting tabs on the woofer frame allow the C1-400x to be installed in four-hole or two-hole mounting configurations.
  
• The C1 woofer drivers benefit from JL Audio's proprietary FEA modeling and woofer design expertise. This knowledge is used to create speakers that can play loud while maintaining a smooth, dynamic, low-distortion sound.
• At the heart of the C1-400x is a proprietary, stamped 4-inch (100 mm) steel frame and DMA-optimized motor system. A mineral-filled, injection-molded polypropylene cone is suspended with a rubber surround at the front and a carefully designed spider at the top of the voice coil to precisely control movement and prevent shock between the voice coil and the backplate.
• These are the same features and materials normally found in much more expensive speakers.
  
• Equipped with a true edge-driven aluminum dome tweeter, the C1 speakers further set themselves apart from other speakers in their category with their superior clarity and definition in the high frequency range.
• The tweeter's design inherently has excellent off-axis response and high-frequency extension. It also benefits from the damping of a silk surround suspension and ferrofluid in the voice coil gap, as well as the superior strength of a neodymium magnetic circuit. A true 2nd order high pass filter is employed to further enhance smoothness and improve power handling.
  
• When it comes to value, C1 is the real deal!
  
• Sold as a pair. Grille not available.
