JL Audio C1 6.5-inch (165mm) Coaxial Speakers

Coaxial Speaker System: 6.5-inch (165 mm) Woofer, 0.75-inch (19 mm) Aluminum Dome Tweeter

JL Audio C1 speakers provide high quality performace in an advance design, which easily mounts behind OEM factory grilles.

For a clean and secure fit, adapter rings are included with purchase of the C1-650x that allow for drop-in installation in vehicles equipped with oversized 6.5-inch and 6.75-inch speaker openings. Without the ring, the speaker will fit into most 6-inch speaker locations as well.

Through the superior quality and design, C1 speakers provide smooth and dynamic sound. At the center of the C1-650x is a proprietary, steel 6.50-inch (165 mm) frame and a DMA-optimized motor system. Equipped with a true, edge-driven, aluminum dome tweeter, JL Audio C1 speakers set themselves apart from the rest. The tweeter’s design also features outstanding off-axis response and high-frequency extension.

Grilles not available.

JL Audio C1 6 x 9-inch (150 x 230mm) Coaxial Speakers

Coaxial Speaker System: 6 x 9-inch (150 x 230 mm) Woofer, 1.0-inch (25 mm) Aluminum Dome Tweeter.

JL Audio C1-690x speakers provide superior quality and audio performance in a design that easily fits behind factory grilles. To aid in fitment, spacer/adaptor rings are also included that allow the C1-690x to be bottom-mounted.

C1 woofer drivers benefit from JL Audio's expertise in low-frequency driver design and use proprietary FEA modeling. Their advanced audio knowledge is used to create speakers that not only can play loudly, but also deliver bold and dynamic sound. At the center of the C1-690x is a proprietary, steel 6 x 9-inch (150 x 230 mm) oval frame and a DMA-optimized motor system.

C1 speakers set themselves apart in terms of high-frequency clarity and definition and are paired with a true, edge-driven, aluminum dome tweeter. The tweeter’s design also features excellent off-axis response and high-frequency extension.

Grilles not available.
