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\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, 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eC7-100ct Design Notes:\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\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\u003e\u003cstrong\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\u003e\u003cstrong\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\u003e\u003cstrong\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. It  also provides improved control of directivity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDesign Bandwidth:\u003c\/strong\u003e\u003cbr\u003eWith 48 dB\/octave filters: 3,000 Hz - 30,000 Hz\u003cbr\u003eWith 24 dB\/octave filters: 4,000 Hz - 30,000 Hz\u003cbr\u003eWith 12 dB\/octave filters: 5,000 Hz - 30,000 Hz\u003c\/p\u003e\n\u003cp\u003eSold  individually, with flush and surface mounting fixtures and hardware.  One 15μF tweeter protection capacitor is also included.\u003c\/p\u003e\n\u003cp\u003eThe  performance of every C7 driver is tested and verified, then assigned a  unique serial number.
