C1-650se Silk Edition — 2-way component system
The C1-650se pairs a 6.5" (165 mm) woofer with a 1" (25 mm) silk dome tweeter in a component configuration designed to drop into factory speaker locations.
The tweeter uses an edge-driven design for strong off-axis response and extended treble. A silk surround suspension and Ferrofluid in the voice coil gap add damping, while a neodymium magnet circuit provides efficiency. Outboard 3rd order high-pass in-line filters with Advanced Tweeter Protection Circuitry are included to guard against high-distortion damage and improve power handling. Both surface and flush tweeter mounts are supplied.
The C1 woofer uses a proprietary stamped steel 6.5" (165 mm) frame and DMA-optimized motor system. A mineral-filled injection-moulded polypropylene cone is suspended with a rubber surround and a flat Conex® spider at the top of the voice coil. Tinsel leads are routed and attached to each spider to prevent fatigue and buzzing.
Multi-application adaptor rings are included, enabling drop-in installation in vehicles with oversized 6.5" and 6.75" openings. Without the ring, the woofers also fit many "6-inch" speaker locations.
Sold as a pair. Grilles not available.

About the JL Audio C1-650se
From our tech experts at CEN
The JL Audio C1-650se is a 6.5" (165mm) 2-way component car speaker system, sold as a pair and rated at 50W RMS. Each set pairs a polypropylene-cone woofer with a 1" edge-driven silk dome tweeter, and includes 3rd-order high-pass in-line filters with Advanced Tweeter Protection Circuitry. Multi-application adaptor rings allow fitment in 6.5", 6.75", and many standard 6" openings.
Who it suits
These suit drivers who want improved sound staging over coaxial speakers, as the component layout lets you position the tweeter independently. Those who prefer a simpler installation at the same power rating may prefer the C1-650x coaxial version.
Our tech experts advise
The woofer mounting hole is 128mm with a 53mm mounting depth — check your door cavity before ordering. Both flush and surface tweeter mounts are included. Grilles are not available for this model. Installation is priced per vehicle; speak to us about fitting at our Nottingham workshop.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: Does the JL Audio C1-650se include crossovers?
A: It includes outboard 3rd order high-pass in-line filters for the tweeters, with Advanced Tweeter Protection Circuitry.
Q: Will the C1-650se fit 6.75 inch speaker openings?
A: Yes. Multi-application adaptor rings are included for drop-in fitting in oversized 6.5 inch and 6.75 inch openings. Without the ring, the woofers also fit many 6 inch locations.
Q: How deep are the C1-650se woofers?
A: The mounting depth is 53 mm with a 128 mm mounting hole.
