JL Audio C3-570 #99021 – 5×7″ Convertible Component Speaker System – Pair

With the JL Audio C3-570 Convertible Component Systems, the same product can be deployed in either configuration, delivering outstanding audio power and quality in each application because there are times when an installation calls for a separate woofer and tweeter and other times when a coaxial is the better approach.

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.

Versatile speaker system for any space

JL Audio’s Evolution C3 speaker systems allow you to choose the best configuration for great sound in your vehicle. Mount the woofers and tweeters separately, and a C3 component system will fill your car with incredibly detailed, rich, and crystal-clear music, perfectly positioned in your listening space. In vehicles with limited space, you can mount the C3 tweeter inside the woofer to create a full-range, coaxial speaker that still performs with breathtaking impact.

Advanced material construction leads to clean musical reproduction

The C3-570 component system uses a 5″x7″ mica-filled polypropylene woofer that covers the midrange and low frequencies strongly and accurately. A specially designed frame resists unwanted resonances, keeping your music free from interference. If you mount the tweeter separately, simply install a phase plug into the woofer and the sound will disperse smoothly throughout your vehicle.

Silk tweeters and versatile crossover networks

The C3 tweeters use ferrofluid cooling to handle extreme levels of high-frequency information without overheating. Mounted separately or coaxially, these 1″ silk dome tweeters broadcast crisp musical detail evenly without harshness. Separate outboard crossovers use premium components to direct the signal flow to your woofers and tweeters. You can select from three midrange settings and four levels of tweeter presence to match the speaker system to your listening environment.
