Product Description

JL Audio C5-525x 5.25″ 2-Way Car Speaker – #99101 – Pair

JL Audio C5-525x system features 5.25-inch (130 mm) woofers with die-cast alloy baskets and Kurt Müller cones and suspensions. The woofer 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 C5 tweeter minimizes tweeter protrusion, allowing C5 coaxials to easily fit behind most factory speaker grilles.

C5 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!

Cast Alloy Baskets

The C5-series coaxial speakers feature cast alloy woofer baskets, while incorporating JL Audio’s patented “Elevated Frame” cooling system. This cooling technology, also found on the flagship ZR component systems and W7 and W6v2 subwoofers, allows air to flow directly across the top plate and onto the voice coil windings to greatly improve linearity at all listening levels.

Woofer Cones

The cone and suspension elements were designed and manufactured by the world-famous Dr. Kurt Müller & Co of Germany. The speakers feature low-mass, mineral-filled polypropylene cones with butyl rubber surrounds. The cone and surround are inherently well damped to deliver an uncolored, neutral midrange without any coloration. The speakers are also equipped with symmetrical-roll, hybrid-weave spiders.


Polyswitch tweeter protection is incorporated into each C5 coaxial crossover network. It monitors current going to the tweeter and will disconnect the tweeter from the signal when it senses overload. Once the volume has been reduced, the protection circuit will reset itself automatically.
