JL Audio C1-690 6 x 9-inch 150 x 230 mm 2-Way Component Speaker System
2-Way Component System: 6 x 9-inch (150 x 230 mm) Woofer, 1.0-inch (25 mm) Aluminum Dome Tweeter
C1 speakers deliver real substance and great audio performance in a format designed for easy fit behind factory grilles.
To facilitate fit, spacer/adaptor rings are included allowing the C1-690 woofers to be installed in bottom-mount applications. Surface and flush mounts are included with C1 tweeters for maximum installation versatility.
C1 woofer drivers benefit from proprietary FEA modeling and JL Audio's expertise in low-frequency driver design. This knowledge is used to create speakers that can play loudly, while maintaining a smooth, dynamic, low distortion sound. At the core of the C1-690 is a proprietary, stamped, steel 6 x 9-inch (150 x 230 mm) oval frame and a DMA-optimized motor system. A mineral-filled, injection-molded polypropylene cone is suspended with a rubber surround on the front, and a carefully engineered flat Conex® spider at the top of the voice coil, to precisely control motion and prevent impact between the voice coil and the back plate. Tinsel leads are carefully routed and attached to the spider to prevent fatigue and buzzing. These are the same kinds of features and materials normally found on much more expensive loudspeakers.
Equipped with a true, edge-driven, 1-inch aluminum dome tweeter, the C1-690 stands further apart from others in its category with superior high-frequency clarity and definition. The tweeter’s design has inherently excellent off-axis response and high-frequency extension. It also benefits from the damping of a silk surround suspension and Ferrofluid in the voice coil gap, along with the superior strength of a neodymium magnet circuit. An in-line, outboard 2nd order high-pass filter, with Advanced Tweeter Protection Circuitry, is included to further enhance smoothness and improve power handling.
