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. 

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

Immaculate highs

This C7-100ct aluminum alloy 1" tweeter features an edge-driven dome design that ensures your highs will be smooth, accurate, and distortion-free. JL Audio uses a specialized corundum coating that's nearly as hard as diamond to push breakup behaviors well beyond the audible range — you won't hear any harshness from this impressive tweeter. And with an elegant grille like no other for custom installation, this tweeter will look sharp no matter where you need to install it.

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 C7-100ct to be neutral, without coloration, so that you can use TüN to craft exactly the right sound for you and your vehicle.
