JL Audio C7-100ct 1" Component Dome Tweeter - Single Tweeter
JL Audio C7-100ct 1" Component Dome Tweeter - Single Tweeter
The C7-100ct represents the pinnacle of JL Audio’s automotive speaker design, crafted with precision engineering and cutting-edge technology. This high-performance component tweeter delivers exceptional high-frequency accuracy, ensuring an immersive and detailed listening experience.
Unrivaled High-Frequency Performance
Designed for active sound systems, the C7-100ct does not include passive crossover networks. Instead, JL Audio recommends using a high-quality tuning DSP, such as the TwK™ 88 or D8, along with a dedicated amplifier channel for each C7 driver. With precise tuning of equalization, delay, and crossover filters, the C7-100ct achieves optimal in-vehicle audio performance.
Advanced Engineering and Design
Premium Dome Diaphragm
Corundum ceramic-coated aluminum alloy diaphragm – Ultra-rigid, lightweight, and environmentally stable
True piston operation at high frequencies – Delivers exceptional detail without added moving mass
Optimized Suspension System
Treated silk S-roll surround – Ensures smooth, controlled movement of the diaphragm
Ferrofluid in the magnetic gap – Enhances damping while maintaining unrestricted excursion
High-Precision Motor Design
Neodymium magnet with U-Yoke motor topology – Provides a high-density magnetic circuit
Under-hung voice coil – Copper-clad aluminum wire on an aluminum former for reduced distortion
Advanced FEA-optimized magnetics – Minimizes even-order distortion, IMD, and AMD, resulting in superior clarity
Acoustic Housing and Directivity Control
Tweeter housing shape enhances sensitivity – Boosts response in a specific frequency range
Improved directivity control – Ensures consistent, balanced sound dispersion
Design Bandwidth and Frequency Response
With 48 dB/octave filters: 3,000 Hz - 30,000 Hz
With 24 dB/octave filters: 4,000 Hz - 30,000 Hz
With 12 dB/octave filters: 5,000 Hz - 30,000 Hz
Each C7 tweeter undergoes rigorous performance verification, and owners can register their unit online to receive a copy of its specific Acoustical Test Report.
