C1 Series 5 x 7 / 6 x 8-inch coaxial speaker system
The C1-570x pairs a 5 x 7 / 6 x 8-inch (125 x 180 mm) woofer with a 0.75-inch (19 mm) aluminium dome tweeter in a coaxial arrangement designed to fit behind factory grilles.
Spacer/adaptor rings are included for bottom-mount installations. The slotted basket mounting holes also allow direct fitment into 6 x 8-inch factory speaker locations.
The woofer uses a proprietary stamped steel 5 x 7-inch (125 x 180 mm) oval frame and a DMA-optimized motor system. The mineral-filled, injection-moulded polypropylene cone is suspended with a rubber surround at the front and a flat Conex® spider at the top of the voice coil, controlling motion precisely and preventing voice coil-to-back-plate contact. Tinsel leads are carefully routed and attached to the spider to prevent fatigue and buzzing.
The edge-driven aluminium dome tweeter delivers high-frequency clarity and strong off-axis response. It features a silk surround suspension, Ferrofluid in the voice coil gap, and a neodymium magnet circuit. A 2nd order high-pass filter improves smoothness and power handling.
Sold as a pair. Grilles not included.

About the JL Audio C1-570X
From our tech experts at CEN
JL Audio C1 Series 7 inch coaxial speakers, with the tweeter mounted in the centre of the woofer, rated at 50w RMS.
Who it suits
Drivers replacing tired factory speakers who want a clear improvement without relocating tweeters. C1 is the straightforward upgrade over factory speakers.
Our tech experts advise
Sizes, adapter rings and harnesses vary by vehicle, year and trim, so we confirm what your car takes before ordering. Door treatment matters as much as the speaker, and JL drivers repay an amplifier. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

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: Will the JL Audio C1-570x fit 6x8 inch speaker locations?
A: Yes. The baskets have slotted mounting holes to fit 6x8 inch factory locations, and bottom-mount brackets are included for bottom-mount applications.
Q: How deep is the C1-570x?
A: The mounting depth is 63 mm, and the tweeter protrudes 12 mm from the mounting surface.
Q: What's in the box with the C1-570x?
A: Two 2-way speakers, two bottom mount brackets, twelve 1-1/2 inch #8 screws, twelve speed clips, two 0.187 inch and two 0.110 inch crimpable female quick slides, and an owner's manual.
