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, 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\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.
