Overview: C1 Speaker Systems

Great performance and unbeatable value, that fits your vehicle.

With C1 speaker systems, no effort was spared to deliver exceptional performance and value, in a format designed to easily fit into factory speaker locations, and behind factory grilles. Benefitting from our decades of expertise in building world-class subwoofer drivers, C1 woofers are engineered to play loudly, while maintaining a smooth and dynamic, low distortion sound. C1 tweeters feature real aluminum domes and silk suspensions for ultra-smooth treble reproduction, with excellent off-axis response and extension. True, 2nd order high-pass filters are included with all C1 speaker systems to further enhance smoothness and power handling. Return to C1 speaker systems.

DMA Logo Aluminum Dome Tweeter LOGO

Dynamic Motor Analysis -
DMA Optimized Motor

Aluminum Dome Tweeter

JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.

True edge-driven, aluminum dome tweeter design is lightweight and delivers refined high-frequency performance, with excellent off-axis response and extension. Silk suspended diaphragms imrpove response and prevent harshness.
