JL Audio C1-075ct

JL Audio C1-075ct | C1 Series 0.75" Component Tweeters

The JL Audio C1-075ct (Part Number: 010-03353-00) is an entry-level high-performance tweeter set designed to provide a significant boost in clarity over factory-installed units. Featuring edge-driven aluminum domes, these tweeters are engineered for refined high-frequency extension and a smooth, natural soundstage. With their compact size and versatile mounting hardware, they are the ideal solution for upgrading dashboards or door sails in a wide range of vehicles.

Product Highlights

• Edge-Driven Aluminum Domes: These 0.75-inch (19 mm) tweeters utilize real aluminum diaphragms for superior stiffness and high-frequency reach. The edge-driven design reduces distortion and improves imaging, delivering crisp detail that outshines standard textile or paper drivers.

• Silk Suspensions & Ferrofluid Cooling: To tame the "ringing" common in metal dome tweeters, JL Audio uses silk suspensions and ferrofluid cooling. This combination damps the diaphragm for smooth reproduction and helps dissipate heat during long, high-volume sessions.

• Advanced Tweeter Protection: The included outboard crossovers feature Advanced Tweeter Protection Circuitry. This electronic system monitors the signal and minimizes the risk of tweeter failure during accidental high-power or distortion peaks.

• True High-Frequency Extension: While most factory tweeters roll off early, the C1-075ct provides detailed reproduction all the way up to 24 kHz, revealing textures in your music you may have never heard before.

Key Features

• 12 dB/Octave High-Pass Filters: The kit includes dedicated in-line, outboard crossover networks. These high-quality filters ensure the tweeters only receive the safe frequency range (above 4 kHz), resulting in cleaner sound and better reliability.

• Flush and Surface Mount Fixtures: JL Audio includes versatile mounting hardware in the box. You can choose a flush-mount look for a factory-integrated appearance or use the surface-mount pods for easier installation on pillars or dashes.

• Neodymium Magnet Motor: The high-energy neodymium magnet provides the driving force needed for high sensitivity and compact physical dimensions, allowing these tweeters to fit into tight factory locations.

• Exceptional Value: As part of the C1 line, these tweeters are positioned to offer a "real deal" upgrade path, providing genuine JL Audio engineering at a highly accessible price point.
