JL Audio C7-100CT 1" Component Tweeter - Each – #99759

JL Audio C7-100ct 100W RMS 1" Component Car Tweeter - #99759

C7-100ct is the pinnacle of JL Audio automotive loudspeaker design, benefiting from our most advanced development tools and a complete commitment to precision manufacturing.

The C7-100ct component tweeter is designed to deliver unparalleled high-frequency performance. Utilizing a corundum ceramic-coated aluminum alloy diaphragm suspended via a treated silk, s-roll surround, it provides spectacularly detailed reproduction of treble frequencies with outstanding off-axis response. Distortion and non-linearities have been minimized through critical optimization of dynamic motor and suspension behaviors.

Passive crossover networks are not included with C7 drivers, as they are designed for active systems. Instead, we recommend a high-quality tuning DSP, such as the JL Audio TwK™ 88 or D8, or a VXi amplifier with built-in DSP, with a dedicated amplifier channel for each C7 loudspeaker in the system. Precise setup of equalization, delay and crossover filters will ensure optimal in-vehicle performance.

JL Audio's flagship car speaker series

Whoa... That's about all I could muster after demoing JL Audio's C7-100ct 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 C7-100ct 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.

C7-100ct Design Notes:

• Dome Diaphragm: Corundum ceramic coated aluminum alloy diaphragm exhibits high stiffness, very low mass and excellent environmental stability. It also helps the tweeter dome to hold its shape and operate as a true piston at higher frequencies, without a penalty in moving mass.
• Suspension Design: The diaphragm's motion is centered, sprung and damped by a treated silk, s-roll surround. Ferrofluid in the magnetic gap acts as a rear suspension element in this design. The two combine to provide optimum damping without unduly restricting excursion.
• Motor Design: The C7-100ct employs a high-density magnetic circuit with a neodymium magnet and U-Yoke motor topology. An under-hung voice coil is employed, wound with copper-clad aluminum wire onto an aluminum voice coil former. Motor magnetics have been precisely optimized utilizing advanced FEA tools to lower even order distortion and IMD/AMD.
• Acoustical Design: The shape of the tweeter housing is designed to boost sensitivity in a very specific bandwidth, helping to flatten the frequency response. It also provides improved control of directivity.

Design Bandwidth:

With 48 dB/octave filters: 3,000 Hz - 30,000 Hz With 24 dB/octave filters: 4,000 Hz - 30,000 Hz With 12 dB/octave filters: 5,000 Hz - 30,000 Hz Sold individually, with flush and surface mounting fixtures and hardware. One 15?F tweeter protection capacitor is also included. The performance of every C7-100ct driver is tested and verified, then assigned a unique serial number.
