About the JL Audio C1-075CT

From our tech experts at CEN

JL Audio C1 Series tweeters, 0.75 inch, supplied with crossovers and rated at 50w RMS.

Who it suits

Drivers building or repairing a front stage where the tweeter needs to sit higher than the door, on the pillar or in the dash.

Our tech experts advise

Placement and aiming change the result more than the tweeter does, and the supplied crossover exists so the tweeter is never asked to play too low. get in touch if you are unsure how these would integrate. 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: Does the JL Audio C1-075ct come with crossovers?

A: Yes. Two inline outboard 12 dB/octave high-pass crossovers are included, with Advanced Tweeter Protection Circuitry.

Q: Can the C1-075ct be flush or surface mounted?

A: Yes. Flush mount housings (with the tweeters installed) and surface mount housings are both supplied. Flush mounting needs a 37 mm hole and 10 mm of depth.

Q: What's in the box with the C1-075ct?

A: Two tweeters with 6 inch wires attached, two crossovers, two flush mount housings, two surface mount housings, two metal spring clips, four 5/8 inch flat head screws, two 25 mm and two 10 mm stud bolts, two M5 nuts and an owner's manual.
