Our take on the JL Audio C2-690tx

JL Audio's Evolution C2 Series speakers

Silk tweeter and Mylar midrange speaker JL Audio's Evolution C2 Series 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.

Product Research


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.

The grill that comes with these speakers measures 9.628" x 6.726". HTH! My Bio: [ Paul  Mar 12, 2017 ]  Staff
I haven't had them put in yet, but they sound great. [ CEDRIC  Jan 07, 2017 ]
Thanks for your question. Country of origin is listed as China. [ Kenny  Nov 12, 2016 ]  Staff
You can go to JL Audios website and pullup the specs to any of their speakers and it will give you the measurements for the enclosure. [ SHELDON  Aug 29, 2015 ]
im not realy shure i used them to replace my stock 6x9 in my doors.they sounded really good amped not alot of low end [ DOUG  Aug 28, 2015 ]
6 by 9 [ TOM  Aug 28, 2015 ]
amp [ TOM  Aug 28, 2015 ]
I have these audio monitors. They are directly connected to my 150 Watt amp. [ Thomas  May 20, 2015 ]
Either way will give you great sound from these speakers [ john  Apr 21, 2015 ]
While you will get good sound out of a head unit only, an amp is going to give you a broader range of volumes that the speakers will be able to produce the ideal sound. I did mine in phases, and started with the the speakers and the head unit, and sounded nice until I had enough in budget to buy an amp, and that took it to a whole different level. So don't be afraid to start with just the speakers and head unit, and then upgrade later to an amp when you can afford a nice one. [ JON A  Apr 21, 2015 ]
Amp would be ideal, but they will sound good off of the head unit. [ SHELDON  Apr 18, 2015 ]
Head unit would be fine, but an amp would provide the best results, both on loudness and quality. [ Joshua  Apr 17, 2015 ]
hey are realy good sounding even on just the deck [ DOUG  Apr 17, 2015 ]
You can tell they have a lot of potential, but running them without an amp is not using their quality at all. Without a doubt run an amp and they will be amazing. [ Jenny  Apr 17, 2015 ]
I have a pair of JL C2690tx in the back deck of my mustang and I'm about to install them in my Camaro also. They will be severely under powered from a head unit. The RMS wattage is probably only 15-20 watts. The 6x9's need at least 75 watts to get the sound you're paying for with the speaker. Hope this helps! [ DAVID A  Apr 17, 2015 ]
