The C5-570 is the largest speaker set available in this series with an asymmetrical 5" x 7" woofer, and is also available as a coaxial speaker set, named the C5-650x. The 5x7" woofers have a mineral filled poly-propelene cone, Butyl rubber surround, 1" voice coil and are mounted in a cast alloy frame using JL Audio's patented Elevated Frame Cooling. The 3/4" silk soft dome tweeters are powered by a Neodymium Magnet, use ferrofluid cooling and damping, and are mounted using a RSR Variable-Angle Flush-Mount System. This tweeter is universal across JL Audios C5 evolution product line. The two included 2-way crossover networks use a 1st order low-pass filter and 2nd order high-pass and comes equipped with a 4-position adjustable tweeter output level, 3-position midrange presence control and features Polyswitch tweeter protection. Much like the tweeter, this crossover is used in all the C5 speaker sets. The C5-570 is designed to be mountable in 5x7" and 6x8" factory locations. Unlike the other sized sets in the C5 line, speaker grilles are not included.
