Features & Specifications




JL Audio C2-525x #99613 – 5.25″ Coaxial Speakers – Pair

The JL Audio C2-525x systems deliver sparkling high-frequency detail, smooth mid-range and powerful mid-bass, thanks to real silk dome tweeters and precision-engineered woofer designs. The JL Audio C2-525x system features 5.25-inch (130 mm) 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.
Tweeters are coaxially mounted and built with 0.75-inch silk dome diaphragms that deliver smooth, extended response, on and off axis. The small size of the C2 tweeter minimizes tweeter protrusion, allowing C2 coaxials to fit behind most factory speaker grilles. Speaker 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.

JL Audio’s Evolution C2 Series speakers

JL Audio’s Evolution C2 Series speakers bring precision sound to your vehicle. They’ll reproduce subtle elements of your music like delicate woodwinds or soprano vocals, then turn on a dime to deliver the deep thrum of the bass or thunder of the drums.

Silk tweeter delivers smooth highs

The C2-525X 5-1/4″ speakers feature rugged polypropylene cones with rubber surrounds that can handle high power without distortion, so you get full-bodied low tones you can really feel. The 3/4″ silk dome tweeters serve up smooth-sounding high frequencies that won’t tax your ears, adding a satisfying dose of realism to your soundstage. Built-in crossovers make sure your tunes play smoothly across the whole musical spectrum. JL Audio includes a pair of grilles that you can use for custom installations.
