Engineered from the ground up, it has exceptional linear excursion capability and outstanding linearity, resulting in solid mid-bass and pure, precise, mid-range performance. 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 a cast-alloy grille tray, one fine mesh steel grille insert and one spiral steel grille insert.\u003c\/p\u003e\n\u003cp\u003eThe performance of every C7 driver is tested and verified, then assigned a unique serial number.
