JL Audio C1-690 6x9 2-Way Component Speaker System

JL Audio C1-690 6x9 2-Way Component Speaker System

The C1-690 speakers deliver outstanding audio performance in a design optimized for seamless factory integration. Built for convenience and versatility, they include spacer/adaptor rings for bottom-mount applications, while surface and flush mounts allow flexible tweeter placement.

Precision Engineering for Powerful Sound
Developed using proprietary FEA modeling and JL Audio’s expertise in low-frequency driver design, the C1-690 ensures high output with smooth, dynamic, and low-distortion sound.

At its core, this system features:
Sturdy Construction – A stamped steel 6 x 9-inch (150 x 230 mm) frame with a DMA-optimized motor system
Durable Cone Design – A mineral-filled, injection-molded polypropylene cone with a rubber surround for enhanced longevity and performance
Precision Control – A flat Conex® spider at the top of the voice coil to maintain stability and prevent impact with the back plate
Secure Tinsel Leads – Carefully routed and attached to the spider to eliminate fatigue and buzzing

These high-quality materials and design elements are typically found in far more expensive loudspeakers, making the C1-690 an exceptional value.

Superior High-Frequency Clarity
Equipped with a true edge-driven 1-inch aluminum dome tweeter, the C1-690 offers exceptional high-frequency definition with smooth off-axis response. Additional enhancements include:
Silk Surround Suspension – For superior damping and clarity
Ferrofluid in the Voice Coil Gap – Enhancing efficiency and longevity
Neodymium Magnet Circuit – Delivering powerful performance in a compact design
Advanced Tweeter Protection Circuitry – A 2nd order high-pass filter ensures smooth operation and improved power handling

Unmatched Value in Its Class
The C1-690 delivers premium sound, smart engineering, and solid durability—all at an incredible value.
