You'll have to custom-mount tweeters or midrange speakers, which usually requires drilling holes and running new wires.

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.

Great Tweeter

Written By G, Alabama on Monday, February 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

Written By Dave, Tinley Park IL. on Tuesday, August 05, 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

Mounted these on dash of my 01 wrangler. What a difference. Great clear highs.

Not bad

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

Written By BenjaminJ, Battle Creek, MI on Tuesday, August 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

Written By Joe, San Francisco, CA on Tuesday, May 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.
