Our take on the JL Audio C2-690tx

by Buck Pomerantz
JL Audio

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

JL Audio's Evolution C2 speakers

Silk tweeter and Mylar midrange speaker JL Audio's Evolution C2 speakers bring precision sound to your vehicle. They'll reproduce subtle elements of your music like delicate woodwinds or soprano vocals, then turn on a dime to deliver the deep thrum of the bass or thunder of the drums.

Silk tweeter delivers smooth highs

The C2-690tx 6"x9" 3-way speakers feature rugged polypropylene cones that can handle high power without distortion, so you get full-bodied low tones you can really feel. The 2" Mylar midrange drivers handle the vocal range, while 3/4" silk dome tweeters serve up smooth-sounding high frequencies that won't tax your ears, adding a satisfying dose of realism to your soundstage. Built-in crossovers make sure your tunes play smoothly across the whole musical spectrum. JL Audio includes a pair of grilles for custom installations.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.


Woofers: The JL Audio Evolution C2-690tx speakers feature a 6x9 injection-molded, mica-filled polypropylene cone woofer with a polyether foam surround. The woofer has a 1-1/4" voice coil and a flat-profile/symmetrical-roll spider. These carefully engineered cones deliver the right combination of stiffness, damping, and off-axis response.

Midrange: The 2" Mylar cone midrange drivers are ferrofluid cooled. The sealed back design provides clean, crisp midrange.

Tweeters: The 3/4" silk dome tweeters are ferrofluid cooled and have neodymium magnets. The edge-driven dome tweeters are smooth, detailed (on or off axis), and provide great overall performance. Silk is lightweight and great for high frequency extension and efficiency. It is also designed for durability in the extreme automotive environment.

Grilles: The Evolution C2-690tx speakers include front-loading protective grilles with a design that combines black steel mesh with satin silver accents. The electroformed logo nameplates can be positioned on the grilles or elsewhere in the vehicle.

Power Handling: JL Audio lists two power figures in the manual; 70 watts continuous power handling and recommended amp power 15-125 watts RMS. We've listed the RMS power recommendation in the specs table.

JL 6x9's

Written By Dalton, Huntington, Indiana on Friday, August 01, 2014
Crutchfield Customer Review (What's this?)
Very, very deep bass. They could definitely take the place of a subwoofer. They could be louder though.
Deep bass and they're JL's

Amazing sound always

Written By R.L., Gainesville on Thursday, April 10, 2014
These speakers sell themselves. JL has always sold quality speakers with an affordable price. They blend in with the rest of my speakers without drowning out the mids or hi's. Purchase these baby's and you won't be sorry.
Great sound. Fits comfortably in the rear speaker deck. Quality!!!!
Update the look maybe?

Bad little 6x9!

Written By Anonymous, Casa Grande AZ on Friday, July 26, 2013
Crutchfield Customer Review (What's this?)
I have only had them a few weeks so this might be a bit soon but I have pushed them vary hard and they work fine. Well worth the price
Best sound I have ever got from this size!
Rubber cover on magnet is large and I had to remove it to fit. Might just be in my car.

JLAudio door speakers

Written By dsayroo, Pearland, Texas on Tuesday, May 14, 2013
Crutchfield Customer Review (What's this?)
The JL Audio C2 series has a great sound. The bass is deep and rich and the highs are crisp. I honestly believe JL Audio makes some of the best speakers on the market net to Focal (which is highly over priced). And I've worked with Kenwood, Infinity, Alpine, Sony, and many other brands as well.
Great sound, easy install, strong construction
More pricey than competitors

Crutchfield Customer Review (What's this?)
Installed in my 2001 Chevy Cavalier coupe and I love 'em! The Punch Brothers never sounded better, I can hear all the instruments clearly including the upright/string bass, which was hard for me to single out before. The magnets are huge compared to the stock speakers I removed, if you have a similar car watch the torsion bars for the trunk. I had to bend them a little to keep them off the speakers when the trunk is closed. Good install instructions and great product.
Great sound

Super sound

Written By Chris G., San Jose, CA on Tuesday, March 06, 2012
I gave these JL Audio speakers a five because I have tested so many other 6x9's on the market, to go into my Harley Road Glide saddlebags and actually kick up some dust. These really did the job. If you like sound quality and thumping bass, then you will not be disappointed by these at all.
Handles the power of a 150w x 4 amplifier, top of the line brand for sure.
I found no cons to note, cost was fair for the products quality and performance.

Amazing speakers, awesome sound!

Written By Anonymous, Orangevale, CA on Friday, February 26, 2010
Crutchfield Customer Review (What's this?)
Bought these for my 91 Camaro for the rear sail panel areas. Got a Kenwood deck rated at 50x4 and 22RMS watts per channel. Have the bass at 5 and bass boost all the way up. Turn up the volume and these don't even begin to distort. The only problem I have now is my old car has no sound deadning material behind them, but I will be fixing that, and then I can't even imagine how much better they will sound!

Baffle boxes suck, don't fit well and in my car and it's hard to poke the screws through and make sure they go into the cars screw holes. Plus they recommend you cut a 1" or so hole in the bottom of them to give it a more deep bass ported sound. If you have the depth for them then go ahead and use them, but otherwise forget them and get some sound deadning material and you will be much better off. Make sure to measure the depth of your mounting hole and compare it to the depth of these speakers too, barely cleared my old school car. And that's the other problem with the baffle boxes, they only add more depth issues. Other then that, simply put these are the best 6x9's I have ever heard. Worth every penny, you WONT be dissapointed! Oh, got the matching front speakers too so it sounds even better having matching quality speakers. Get a good deck too!
