Overview

Our take on the JL Audio C1-075ct

After an extensive tour of JL Audio HQ, I got the opportunity to talk to their engineering and development team about the current JL Audio lineup and upcoming projects. Given all the work they're doing with premium car audio, I was surprised by how excited they were for customers to hear their workhorse C1 Series — speakers designed for drivers simply looking for a sensible factory speaker replacement, not necessarily an audiophile-grade solution. The reason for that excitement, once I heard it, made perfect sense — every JL Audio speaker must uphold the quality and sound associated with the name. You may be looking for something that's just listenable, but what you'll get with the C1 Series is an audio experience that puts it at the top of its class. And then, just maybe, you'll end up being a JL Audio fan for life.

Take your highs to a new level

These C1 Series C1-075ct 3/4" aluminum dome tweeters stand apart from other component tweeters at this price. Their edge-driven design gives you a smooth response and minimizes distortion. You'll experience crisp detail in the high frequencies and incredible imaging that will make your factory tweeters hide in shame. Included in-line crossovers ensure that these tweeters receive the right frequencies, and JL Audio supplies flush- and surface-mount solutions for the perfect installation.

  • flush- and surface-mount hardware included

Crutchfield Customer Review (What's this?)

Quick background- I have the Sony upgraded system with nav and subwoofer. I'd already replaced the door speakers with Polk 4x6 and a Kicker Hideway sub. Mostly pleased with the system but hadn't replaced the stock A pillar tweeters- partly because I wasn't convinced they did anything- they are mostly invisible sonically speaking. I had a lot of reward points so I decided to spend them on these tweeters. I am pleasantly surprised by the sound quality and depth and range they bring to my music. They really shine with good source material, and definitely worth the money. Install took about an hour. If you have an '09-14 F150 with the A pillar tweeters, these are a perfect flush mount option. Either bracket works fine to secure them from the back- so not sure why Crutchfield lists them as surface mount only. Overall very happy and would recommend to others.

Pros: JL Audio quality, good sound, fair price

Cons: None that I'm aware of.

Crutchfield Customer Review (What's this?)

I installed these in my 2001 Honda Accord. I had to do some slight modifications to mount them in the factory locations in the dash. They sound great. Made significant sound difference from the factory speakers. Clear crisp sound. Very pleased.

Features

Tweeters: The 3/4" edge-driven, aluminum dome tweeters are damped by a silk surround suspension. Flush and surface tweeter mounting brackets are included.

Tweeter Dimensions:

  Frame Diameter Cutout Diameter Mounting Height Mounting Depth
Flush Mount 1.675" 1.448" 0.248" 0.863"
Surface Mount 1.712" Screw Holes Only 0.748" 0.508" (Screw Depth)

Crossovers: The in-line tweeter crossovers are 2nd order (12 dB/octave slope) and the 30" input and 15" output wires are attached. The input wires are terminated with female quick slides and the output wires are terminated with male quick slides that plug into the terminals on the wires attached to the tweeters. The electronic tweeter protection circuit is designed to minimize the possibility of tweeter failure. It monitors current going to the tweeter and will disconnect the tweeter from the signal when it senses overload. Once the volume has been reduced, the protection circuit will reset itself automatically.

  • Height: 1"
  • Depth: 1-3/8"
