Amazing JL Audio sound at an unbeatable value!

For those who appreciate substance and great audio performance… C1 is the real deal at a very sweet price!

Benefiting from our expertise in building world-class subwoofer drivers, the woofers in C1 components and coaxials are engineered to get loud, while maintaining smooth, dynamic, low distortion sound. C1 speakers use real aluminum dome tweeters with silk suspensions for refined high-frequency performance and improved response. Coaxial models are equipped with true, 2nd order high-pass filters on-board, for smooth, accurate treble reproduction and low distortion. Component systems include in-line, outboard 2nd order high-pass filters, with Advanced Tweeter Protection Circuitry. Surface and flush mount fixtures are also standard with C1 component tweeters.

To ensure good fit into most vehicles, we offer a wide range of C1 sizes, all with moderate depths and minimal tweeter protrusions, to install neatly in to most factory speaker locations, behind factory grilles.

Great performance and unbeatable value...

...that fits your vehicle.

Technology

JL Audio’s engineering department is at the forefront of research into fundamental loudspeaker behavior. We have developed proprietary analysis systems and invested heavily in state-of-the-art manufacturing and testing. This has borne numerous products widely considered as reference standards and has also resulted in many U.S. and International Patents issued for technologies that refine and extend the audio performance envelope.
