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.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003ePassive 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.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eC7-100ct Design Notes:\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eDome Diaphragm:\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eSuspension Design:\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eMotor Design:\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eAcoustical Design:\u003c\/strong\u003e The shape of the tweeter housing is designed to boost sensitivity in a very specific bandwidth, helping to flatten the frequency response.
