Features & Specifications




JL Audio C2-525 #99620 – 2-Way Component System – Pair

The JL Audio C2-525 systems deliver sparkling high-frequency detail, smooth mid-range and powerful mid-bass, thanks to real silk dome tweeters and long linear excursion woofer designs.

The C2-525 system features 5.25-inch (130 mm) component woofers with mineral-filled polypropylene cones, long excursion capabilities and stamped steel frames. The woofer design benefits from JL Audio’s vast woofer design experience and advanced modeling systems.The C2 component tweeters are built with 0.75-inch silk dome diaphragms that deliver smooth, extended response, on and off axis. Flush-mounting and surface-mounting fixtures are included to fit a wide variety of installation needs.

C2 crossover networks are compact and built with premium component parts, including Mylar® capacitors and segmented air-core inductors. Three levels of tweeter attenuation are provided, as well as a tweeter protector. Woofer grilles are included, each consisting of a black grille tray with satin silver accents and a black steel mesh grille with an electroformed JL Audio logo.

Rugged components

I’ve installed enough car speakers to know that if you’re going through the effort of taking off your door panels and creating tweeter locations, you’ll want to choose a well-built speaker system that’s going to live a long life in your car. Well, you’ve landed on the right page — this JL Audio C2-525 component speaker system is about as sturdily built and smooth-sounding as it gets for the price.

Powerful woofers for satisfying sound

Framed by a stamped steel basket, the 5-1/4″ mineral-filled polypropylene woofer delivers the low frequencies reliably play after play, giving a solid foundation to your favorite music. The butyl rubber surround supports a cone that’s designed for extra excursion, giving extended low-frequency response.

Silk tweeters and versatile crossover networks

The C2 3/4″ silk dome tweeters gracefully handle the high-frequencies, broadcasting crisp musical detail evenly and without harshness. JL Audio includes surface- and flush-mount hardware so you’ll be able to install the tweeters in the best possible location in your vehicle. Separate crossovers use premium components to direct the signal flow to your woofers and tweeters, and you can select from the three levels of tweeter attenuation to match the speaker system to your listening environment.
