Distortion and non linearities have been minimized through critical optimization of dynamic motor and suspension behaviors.\u003c\/li\u003e\n\u003cli\u003ePassive crossover networks are not included through C7-Series drivers, as they are designed for active systems.  Instead, we recommend a high quality tuning DSP, such as the JL Audio TWK 88 \/ D 8, or a VXI-Series amplifier through built in DSP, and a dedicated amplifier channel for each C7-Series loudspeaker in the system. Precise setup of equalization, delay and crossover filters will ensure optimal in vehicle performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDesign bandwidth:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThrough 48 and 24 and 12 dB \/ octave filters: 3000 and 4000 and 5000 - 30,000 hz\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSold individually, through flush and surface mounting fixtures and hardware.  One 15 μF Tweeter protection capacitor is also included.\u003c\/li\u003e\n\u003cli\u003eThe performance of every C7-Series driver is tested and verified, then assigned a unique serial number.  Register your C7-Series loudspeaker online to receive a copy of its specific acoustical test report.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/fBrRRl92PZ8?si=k6Tfth6Ljofw-per\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen\u003e\u003c\/iframe\u003e","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":43456206929987,"sku":"JLC7-100CT","price":499.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2521\/5218\/files\/JLC7-100CT.jpg?v=1782362797","url":"https:\/\/azelectronics.ca\/products\/jl-audio-jlc7-100ct-1-c7-series-ceramic-coated-aluminum-tweeter","provider":"AZ Electronics","version":"1.0","type":"link"}
