Premium Entry-Level Coaxials for a Clean, Powerful Upgrade

Built as the perfect first step into premium car audio, offering a noticeable upgrade over factory speakers without the premium price tag. Its mineral-filled polypropylene woofer delivers punchy, accurate midbass, while the durable rubber surround ensures long-lasting, distortion-free performance. A true JL Audio value, ideal for anyone seeking better clarity and impact from their everyday sound system.

Aluminum Dome Tweeters for Crisp, Balanced Sound

The C1 Series features an aluminum edge-driven dome tweeter that delivers clear, controlled highs with wide dispersion and minimal distortion, ensuring precise treble reproduction. Paired with a woofer engineered for natural roll-off, it creates a smooth frequency transition for balanced, full-range sound throughout your vehicle.

 

Efficient, OEM-Friendly Upgrade for Factory

These C1 Series speakers feature a 4-ohm impedance and high sensitivity, delivering excellent performance with factory radios while responding even better to aftermarket amplifiers. Designed without aftermarket grilles, they fit seamlessly behind factory panels, providing a clean, factory-look installation with no compromises.

  • One of the best in the market! Powerful lows and its high frequencies are really clear and not irritating to listen. It is also not that expensive compared to other high-quality speakers. I would buy another pair again.

  • Price is excellent for a JL Audio speaker. Sound quality is exceptional for the value, and what’s more is that these are some great looking speakers. Love the yellow and black combo.

  • Fan of the yellow finish of the cone. Looks wise, it is one of the best I have ever seen. The sound is on par with how good looking it is too. Great balance with the mids and highs. Good bass too for the size.

  • Replaced the stock speakers in my truck with these, and the difference is huge. Clear highs, a nice punch on the low end, and crystal clarity for podcasts. Install was super simple. Highly recommend!
