The JL Audio C7-100ct Component Tweeter is designed to deliver unparalleled high-frequency performance. Utilising 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 minimised through critical optimisation of dynamic motor and suspension behaviors.
Features
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 as a pair, with flush and surface mounting fixtures and hardware. Two 15μF tweeter protection capacitosr are also included.
