About the JL Audio C1-100ct

Starter speakers like no other

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 C1-100ct 1" 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.

Features

Tweeters: The 1" 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 1.970" 1.734" 0.330" 0.931"
Surface Mount 2.005" Screw Holes Only 0.872" 0.535" (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.

Crossover Dimensions:

  • Width: 2" (3" including wire)
  • Height: 1"
  • Depth: 1-3/8"

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
because other than my head unit and factory tweeters my entire system is JL Audio, this completes my system [ Mark  Feb 11, 2019 ]
A
Good match for my car where I have to use the stock stereo and because it is a convertible, needed it to be loud and efficient and high quality. Choice was these vs the Focal Integration. I liked the workmanship and attention to detail on the JL Audio tweeters better. [ chris  Nov 04, 2018 ]
A
JL Audio and the size [ Bryan  Oct 09, 2018 ]
A
For the price, you can't beat the quality and reliability of JL audio [ ryan  Aug 13, 2018 ]
A
Need a new aftermarket pair of good quality tweeters (JL Audio) to match with 6 pioneer door speakers and 2 8-inch Polk subwoofers. I already bought from Crutchfield the JLAudio -800 amplifier. Later, I will get the top of the line Pioneer AVH 4201 or 8201. [ DONALD  Mar 16, 2018 ]
A
Jl audio products sound good.owned them before. [ ANTHONY R  Feb 27, 2018 ]
A
To handle the extra power from amp install and better sound than factory. [ BRUCE  Jan 13, 2018 ]
A
I have a set of jl c5 650 components and I will add these to them for a lil more tweet to my front speaker set up in my 2015 Sierra crew cab I have all jl and I'm very happy [ Ernesto  Jan 01, 2018 ]
