About the JL Audio C7-350cm

JL Audio's flagship car speaker series

Whoa... That's about all I could muster after demoing JL Audio's C7 component system at their headquarters. I was floored. Track to track, moment to moment, I was astounded by the clarity and presence reproduced by these speakers. Impactful loudness, rich detail, imaging that seemed almost magical — all of it facilitated an emotional connection that rivaled live performance.

Whoa... That's about all I could muster after demoing JL Audio's C7 component system at their headquarters. I was floored. Track to track, moment to moment, I was astounded by the clarity and presence reproduced by these speakers. Impactful loudness, rich detail, imaging that seemed almost magical — all of it facilitated an emotional connection that rivaled live performance. 

Note: The C7 Series 6-1/2" woofer, 3-1/2" midrange, and 1" tweeter are all sold singly.

The voice of your system

This C7-350cm 3-1/2" midrange driver is a powerhouse, handling frequencies from 300 to 10,000 Hz, which account for most vocals, piano, and guitar. Have no doubt — this little guy is seriously up to the task. JL Audio uses a mineral-filled polypropylene cone for excellent damping and a specially designed concave dust cap to make it a versatile player within a 3-way system. A one-of-a-kind machined motor and oversized voice coil ensure minimal distortion under any appropriate powering scenario. And with an elegant grille like no other for custom installation, this speaker will be the star of your dream system.  

Make it part of an active system

The ultra-premium C7 Series has been years in the making, but its unveiling was contingent on JL Audio providing the ultimate tuning solution for optimal speaker performance — and that's TüN, their latest audio-tuning software. Each C7 speaker is sold à la carte to give you the freedom to design whatever system your ears desire. You'll need an active crossover to use C7 speakers —  JL Audio' recommends using their TwK™ 88 digital signal processor, which gives you access to the awesome sound-shaping power that TüN offers. The JL Audio engineers designed the C7-350cm to be neutral, without coloration, so that you can use TüN to craft exactly the right sound for you and your vehicle.
