JL AUDIO C3-570 - 5x7" Compo-/Coaxsystem

C3-570
2-Way Convertible Component / Coaxial System: 5 x 7 / 6 x 8-inch (125 x 180 mm) Woofer, 1-inch (25 mm) Silk Dome Tweeter

• There are times when an installation calls for a separate woofer and tweeter and other times when a coaxial is the better approach. With the Evolution C3 Convertible Component Systems, the same product can be deployed in either configuration, delivering outstanding audio power and quality in each application.
• Many people mistakenly believe that an oval speaker cannot perform as well as a round one, leading to many instances of 5.25-inch speakers being installed into 5 x 7-inch openings. JL Audio has put in the engineering time and effort to create fantastic-sounding speakers that drop into oval openings and deliver equivalent performance to our 6.5-inch (165 mm) round speaker systems... guaranteed. So, don't make the mistake of losing cone area and efficiency by stepping down to a smaller round speaker... these ovals are as impressive as our round format systems.
• The C3-570 system features 5 x 7 / 6 x 8-inch (125 x 180 mm) component woofers with oversized 1.2-inch (30.5 mm) voice coils, mineral-filled polypropylene cones and injection-molded polymer baskets. The woofer design benefits from JL Audio's vast woofer design experience and advanced modeling systems.
• The C3 tweeters are built with 1-inch silk dome diaphragms that deliver powerful, extended response, on and off axis. Flush-mounting and surface-mounting fixtures are included to fit a wide variety of installation needs. They can also be mounted onto the woofers in a coaxial format using the included fixtures.
• C3 crossover networks are compact and built with premium component parts, including Mylar® capacitors and segmented air-core inductors. Four levels of tweeter attenuation are provided, as well as three levels of mid-range presence adjustment, for twelve possible voicing combinations!
• Woofer grilles are not available for this product.
