JL Audio C7-100ct
Small but powerful. This tweeter might be just 1" but it sure delivers the most clarity and loudness an audiophile could desire. Crafted by one of the leading makers of car audio technology, JL Audio truly provides the sound of the generation.
Here are some Design Notes from the manufacturer:
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.
