JL Audio C6-100ct
Upgrade Your Vehicle With Confidence. This Is Built to Fit, Perform, and Last
JL Audio C6-100ct | C6 Series 1" Component Tweeters (Single)
The JL Audio C6-100ct (Part Number: 010-03390-00) is a premium component tweeter that draws its DNA from JL Audio's flagship C7 series. Engineered for high-end active systems, these tweeters prioritize refined fidelity and exceptional precision. By utilizing edge-driven silk domes and advanced motor modeling, they deliver a "sparkling" high-frequency detail that remains smooth and natural, making them a top-tier choice for audiophiles looking to build a custom, high-performance soundstage.
Product Highlights
Edge-Driven Pure Silk Domes: These 1-inch (25 mm) tweeters feature a pure silk dome diaphragm that provides incredibly smooth high-frequency reproduction. The edge-driven design creates a wide, balanced soundstage with excellent off-axis response, ensuring you hear every detail even if the tweeters aren't aimed directly at you.
Active System Optimization: Unlike entry-level tweeters, the C6-100ct is purpose-built for active systems. By removing passive crossovers, JL Audio allows system designers to use a Digital Signal Processor (DSP) to precisely tune equalization, delay, and crossover points for a seamless blend with C6 woofers.
DMA-Optimized Neodymium Motor: Using proprietary Dynamic Motor Analysis (DMA), JL Audio has optimized the neodymium motor to reduce distortion and improve transient performance. This results in a highly linear response that can handle complex musical passages with ease.
Ferrofluid Cooling & Damping: To ensure long-term reliability and consistent performance during high-volume sessions, the C6-100ct utilizes ferrofluid cooling. This helps dissipate heat from the voice coil and damps the movement for a smoother, non-fatiguing sound.
Key Features
Solid-State Tweeter Protection: The C6-100ct features an automatic, solid-state protection circuit. This system monitors the signal and helps prevent tweeter failure during accidental power peaks or distortion, safeguarding your investment.
Versatile Mounting Hardware: JL Audio includes both flush-mount and surface-mount fixtures in the box. This flexibility allows for a clean, integrated factory look in dashboards or creative surface placements on pillars for better imaging.
Compact Engineering: Despite its powerful output, the tweeter is designed with a compact motor system. This allows it to fit into tight factory locations where depth is often limited, making high-end upgrades more accessible in modern vehicles.
C7-Derived Technology: By applying the modeling systems and design experience gained from the ultra-premium C7 line, the C6 series offers flagship-level performance at a more accessible mid-level price point.
