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 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\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eMade in the USA with Global Components\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSold individually, with a cast-alloy grille tray, one fine mesh steel grille insert and one spiral steel grille insert\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDESIGN FEATURES:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCone and Dust Cap:\u003c\/strong\u003e Vacuum-formed, mineral-filled polypropylene material offers excellent damping and low mass.
