Utilizing a corundum ceramic-coated aluminium alloy diaphragm suspended via treated silk, s-roll surround, it provides spectacularly detailed reproduction of treble frequencies with an outstanding off-axis response. Distortion and non-linearities have been minimized through critical optimization of dynamic motor and suspension behaviours.\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\u003cspan\u003eSold individually, with flush and surface mounting fixtures and hardware.

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\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSuspension Design\u003c\/strong\u003e: The diaphragm’s motion is centred, sprung and damped by 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\u003c\/li\u003e\n\u003cli\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 aluminium wire onto an aluminium 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\u003c\/li\u003e\n\u003cli\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.
