Hear more in your music

JL Audio's C5075-CT 3/4" silk dome tweeters bring your high-frequency sounds into crisp, clear focus. You'll hear more details in your music, with a real sense of where each instrument is placed in the mix.

Each tweeter comes with mounting hardware for flush- or surface-mounting, and JL Audio's ratcheting swivel rotation (RSR) flush-mount system permits precise aiming even after installation. The C5075-CT tweeters feature strong, ferrofluid-cooled neodymium magnets for superior performance.

Note: These tweeters must be used with the supplied in-line high-pass crossover filters or another appropriate external crossover. Failure to do so could lead to damage to the tweeters not covered under the warranty.

Installation note: You'll need a pair of our universal backstraps to install these tweeters in the factory locations.

Crutchfield Customer Review (What's this?)

Tremendous, warm, smooth sound without the shrill of most tweeters. The ability to angle the tweeters is a huge benefit for those looking to optimize the sound stage in their vehicles while the 12db crossovers ensure that only the proper frequency range gets through. Yet another top of the line JL Audio product!

Pros: Silk Dome Smoothness; Angle Adjustable; In Line Crossover

Cons: None

Replaced my factory speakers, great sounding tweeters, the difference is amazing!

Pros: Very crisp sounding!

Cons: Had to modify to make them fit the pillars, but worth the extra work.

Tweeters for my boat

Crutchfield Customer Review (What's this?)

Got these to expand the high end of my JL C2-690x 6x9 speakers in the saloon of my catamaran (where we also live). One of the 6x9s is behind a TV and I wanted to improve the power and stereo imaging by installing these above the 6x9s. It worked like a charm! I'm very pleased with the smooth sound of these tweeters. Their tone blends seamlessly with the 690s and they were easy to install. It's great that the kit comes with a 4kHz high pass crossover, so no need to get extra stuff. If you're looking for added smooth spacious high frequencies, these tweeters are a great investment.

Pros: Awesome sound, easy to install, included crossover

Cons: More expensive than most, but worth it IMHO.

Creates crisp clear sound over the old speakers. Thinking about replacing the rest of the speakers


Cons: Had to get the book to find out what was positive and negative. Was not really a con,. That was what I bought the book for when i bought the car.

Great Tweeter

G from Alabama on 2/23/2015

Crutchfield Customer Review (What's this?)

You know the difference right away with these tweeters. The highs are very warm not harsh and they are very clear. I installed these in a 2013 Camaro to replace the factory tweeters I also added Focal PC 165 speakers in the door and driving these with the Alpine PDR-F50 Amp. These tweeter were the finishing touch for an excellent soundstage.

Pros: Very warm with no harshness at all. I hear instruments that I never heard before. The sound is excellent at low and high volumes. Not a disapointment at all.

Cons: None

JL C5075-CT tweeters

Dave from Tinley Park IL. on 8/5/2014

Crutchfield Customer Review (What's this?)

These tweeters are a noticeable difference from the factory paper tweeters. Having the JL name on them I'm sure they are of good quality they are known for. The only downside is that they are a little pricey. Could have spent a little less on another brand with other 5 star ratings.

Pros: Sound quality

Cons: Pricey

Not bad

Dave from Pittsburgh, Pa. on 4/2/2012

Crutchfield Customer Review (What's this?)

I have an 03 Silverado WT. and an 04 F-250 SD. Crutchfield is in both. The C5075-CT's work well in the Ford. These are "add-ons". As I am running a factory head, with a small amp and Four Boston two-ways, (Crutchfield), in the factory locations. These tweeters add an extra "wow". Long story short., I like them.

Pros: Good service, Good product.

Cons: Da?

Excellent Upgrade for 2012 Lincoln MKZ Hybrid

BenjaminJ from Battle Creek, MI on 8/23/2011

Crutchfield Customer Review (What's this?)

C5-075CT are excellent tweeters. They solve one of the many problems I have with my new 2012 Lincoln MKZ Hybrid. Neither the standard Lincoln Sound System nor the upgraded version have top quality speakers...I elected to upgrade the sound system on my own rather than purchasing the upgraded Lincoln system, which was costly and didn't suit my ears. (Lots of speakers, but only moderate quality sound) One of the many issues with the Lincoln system is that the center speaker overpowers the component speakers in the door, so rather than getting the 'surround feel' you get the feeling that someone is talking to you from the center of the car. (The stock speakers in the doors simply prevent the feeling of dead spots in the sound system). I selected these tweeters due to their high sensitivity and ability to put out a strong volume even with a weak head unit (stock from Ford). The C5-075ct did the trick. Now that they are installed, I have the feeling that the mid/high frequency is coming evenly from all over the front of the vehicle rather than simply the center channel. The sound clarity and complexity are excellent. These tweeters reproduce the high notes exceedingly well without me having the feeling that a cat is clawing at the chalk board. I definitely recommend these tweeters.



Worth the Money

Joe from San Francisco, CA on 5/18/2010

Crutchfield Customer Review (What's this?)

I upgraded to these JL 5075 tweeters after one of my polks up and died on me. I was a bit skeptical at first due to the price, but once installed I immediately knew where that extra money went. Awesome sound clarity, smooth delivery without being tinny sounding at all. I have these powered by a Rockford Fosgate amp running 50 watts RMS per tweeter, they add a level of detail and actual volume that I didn't know tweeters could even provide, highly recommended.

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

After trying multiple tweeters from different companies which were way too harsh and ear piercing, I decided to give these a try. I've read and heard that these aren't harsh like other tweeters and are some of the smoothest. Fingers crossed. [ Justin  May 03, 2017 ]
looking for my other tweeters 4 the c2650 couldn't find so i went with these!!thank u [ Corey Wayne  Nov 10, 2016 ]
I needed to expand the high frequency response and improve the stereo imaging of the speakers in the main saloon of my sailboat and these match up well with the JL Audio C690-tx speakers that I already have. [ David  Jul 04, 2016 ]
I run all the same components in a single system. I prefer jl audio over all and have since the 1990's. [ Steven  Feb 11, 2016 ]
