C1 Series 6 x 9-inch (150 x 230 mm) 3-way coaxial speaker system
The C1-690tx is a 3-way coaxial system built around a 6 x 9 inch (150 x 230 mm) woofer, a 1.0 inch (25 mm) aluminium dome tweeter, and a 0.75 inch (19 mm) aluminium dome super tweeter. C1 speakers are designed to deliver solid audio performance while fitting easily behind factory grilles. Spacer adaptor rings are included for bottom-mount applications such as parcel shelves.
The woofer uses a proprietary stamped steel 6 x 9 inch (150 x 230 mm) oval frame and a DMA-optimized motor system, developed using FEA modelling and JL Audio's low-frequency driver expertise. A 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 and preventing voice coil-to-back-plate contact. Tinsel leads are carefully routed and attached to the spider to prevent fatigue and buzzing.
The dual edge-driven aluminium dome tweeters deliver high-frequency clarity and separation with good off-axis response. Both tweeters feature silk surround suspensions, Ferrofluid in the voice coil gaps, and neodymium magnetics. A mixed-order filter network improves smoothness and power handling.
Sold as a pair. Grilles not included.

Our tech experts advise

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: What is the difference between the JL Audio C1-690tx and C1-690x?
A: The C1-690tx is a 3-way design with a 1 inch aluminium dome tweeter plus a 0.75 inch super tweeter and a 36 Hz - 24 kHz response. The C1-690x is a 2-way with a single 1 inch aluminium dome tweeter and a 39 Hz - 22 kHz response. Both are rated at 60W RMS.
Q: Can the C1-690tx be bottom mounted?
A: Yes. Spacer adaptor rings are included to allow installation in bottom-mount applications.
Q: Are grilles included with the C1-690tx?
A: No. The C1-690tx is sold as a pair without grilles.
