JL Audio C1-650x 6.5-inch (165 Mm) Coaxial Speaker System
Product Overview
Extended 1+1 Year Brand Warranty
Coaxial Speaker System: 6.5-inch (165 mm) Woofer, 0.75-inch (19 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, multi-application adaptor rings are included with the C1-650x allowing easy, 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 many "6-inch" speaker locations as well.
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 C1-650x is a proprietary, stamped, steel 6.50-inch (165 mm) 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 the voice coil's motion. 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, aluminum dome tweeter, C1 speakers stand 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. A true, 2nd order high-pass filter is employed to further enhance smoothness and improve power handling.
When it comes to value, C1 is the real deal!

Frequently Asked Questions (FAQ)
Q: Is the JL Audio C1-650x a coaxial or a component speaker set?
A: The C1-650x is a 2-way coaxial speaker set, meaning the aluminum tweeter is mounted directly above the center of the woofer cone on a bridge structure. (If you are looking for separate tweeters and woofers, check out the JL Audio C1-650 component set).
Q: Do I need an external amplifier to run these speakers?
A: No. Due to their high efficiency (93 dB sensitivity @ 2.83V/1m), the C1-650x speakers will sound significantly louder and clearer than stock speakers when powered directly by a factory or aftermarket head unit. However, powering them with a 35W–50W RMS 4-channel amplifier will unlock deeper bass punch and headroom.
Q: Will these fit both 6.5-inch and 6.75-inch speaker openings?
A: Yes. The C1-650x features a multi-pattern steel frame and includes multi-application adapter rings, allowing drop-in installation in both standard 6.5" and oversized 6.75" factory door cutouts.
Q: Are speaker grilles included in the box?
A: No, the C1-650x is engineered specifically as an OEM replacement speaker designed to fit hidden behind your vehicle's factory door panels, so external grilles are not included.
