JL AUDIO 1" (25 Mm) Tweeter 100W Rms (Sold As Each) -C7-100ct

C7 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 aluminium alloy diaphragm suspended via treated silk, s-roll surround, it provides spectacularly detailed reproduction of treble frequencies with an outstanding off-axis response. Distortion and non-linearities have been minimized through critical optimization of dynamic motor and suspension behaviours.

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, and 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.

Sold individually, with flush and surface mounting fixtures and hardware. One 15μF tweeter protection capacitor is also included.

DESIGN FEATURES:

• Dome Diaphragm: Corundum ceramic-coated aluminium 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 centred, sprung and damped by 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 aluminium wire onto an aluminium 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
