JL Audio's Evolution C2 speakers

Side view of Evolution C2 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

Silk tweeter

The C2-650X 6-3/4" speakers feature rugged polypropylene cones that can handle high power without distortion, so you get full-bodied low tones you can really feel. The 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.

Note: JL Audio describes this model as a 6-1/2" speaker. Most manufacturers designate this same frame size as a 6-3/4" speaker. For simplicity's sake we list it as a 6-3/4" speaker.

Why replace your factory 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.

Features

Woofers: The JL Audio Evolution C2-650x coaxial speakers feature a 6-3/4 injection-molded, mica-filled polypropylene cone woofer with a butyl rubber surround. Each woofer has a 1.0" voice coil on a Kapton Former, a symmetrical roll spider and a Ferrite magnet. These carefully engineered cones deliver the right combination of stiffness, damping, and off-axis response. The speaker also provides adequate bass, thanks to its ample mechanical clearance, optimized suspension and balanced motor design.

Tweeters: The Evolution C2-650x coaxial speakers feature a 0.75" silk dome, ferrofluid-cooled tweeter with a damping neodymium magnet. The edge-driven silk dome tweeter is smooth, detailed (on or off axis), and provides 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 C2-650x coaxial speakers include front-loading protective grilles with a design that combines black steel mesh with satin silver accents. Electroformed logo nameplates can be positioned on the grilles or elsewhere in the vehicle, according to the needs of the installation.

Power Handling: JL Audio lists two power figures in the manual; 60 watts continuous power handling and recommended amp power 15-100 watts RMS. We've listed the RMS power recommendation in the specs table.

Nice upgrade from the polks

Pros: Crisp and clear

Cons: None

Sounds Great!

Crutchfield Customer Review (What's this?)

Could have spent more money , but these were a perfect fit for my Honda Ridgline! Highly recommend get the Dynamat Speaker Kit in addition when installing. Makes a huge difference. Very Pleased with Crutchfield and JL Audio

Pleasantly suprised

Written By cuznsteve, Oakland gardens NY on Sunday, July 07, 2013

Crutchfield Customer Review (What's this?)

Really outstanding sounds, I took a leap of faith in spending this much but I figured maybe this would be the last time. (I had installed 3 cars already and they ended upo being sold) This ones is a keeper , so I went sort of all the way , partially.

Pros: Couldn't ask for anything more.

Cons: none

Great sounding speakers!

Written By Leakgator, Ellijay, GA on Sunday, March 24, 2013

Crutchfield Customer Review (What's this?)

I bought these speakers for the roll bar in my 2012 jeep wrangler unlimited. They fit, but they don't fit the existing screw holes. You have to make your own screw holes. I bought them for filler, because I have the JL Audio c5 components in the front. I am powering them off a JL Audio HD 900/5. I was pleasantly surprised with how great they sound. Very clear and nice and punchy. Very good detail.

Pros: Sound quality

Cons: None do far

big improvement

brand new 2013 sierra extra cab. ripped out the speakers and what a difference! awesome sound. just the speakers were changed and such a big improvement.

Pros: better sound

Cons: you forget what crappy speakers sound like

Nice Sound that doesn't Break the Bank

Written By LuisV, Westchester, NY on Monday, June 11, 2012

Crutchfield Customer Review (What's this?)

For the price you can't go wrong with these speakers. They handle a good amount of power and sound better than their price point suggests. These were purchased as rear fill and to complement a set of JL Audio C2650 component speakers. Their mid to low end sound very similar to the components; however, the upper registers sound slightly different to me. Although there is a slight sonic difference, I would still recommend them to friends and family as the ever so slight sound difference is more than likely due to the lower tweeter mount.

Pros: Great price point, can handle plenty of power and sound better than their price point would suggest.

Cons: Could possibly benefit from an angled tweeter mount.

Incredible.

Written By ashevillain, Asheville, NC on Tuesday, June 05, 2012

Crutchfield Customer Review (What's this?)

These speakers are incredible. I purchased 2 pairs to install in my 2003 Civic EX Sedan. Crutchfield doesn't list these as compatible with this vehicle but I always like a good challenge.

For the front doors the mounting depth (magnet and basket) is too deep for the speaker wells. I used some 3rd party speaker adapters and also had to add some rubber grommets to get a bit more spacing.

In the rear deck the mounting height (tweeter protrusion plus speaker adapter) is listed as the roadblock. Well, Crutchfield sent the wrong adapters to begin with and the 3rd party adapters I had didn't line up with the holes either. So I did an easy workaround. Mounted the speakers directly to the factory mounting holes via speed clips!

In both cases I also used some Dynamat to deaden any noise (also gave a tiny bit of spacing between the sheet metal and the speaker). The Dynamat cleaned up the sound immensely. I paired these speakers with a Kenwood KDC-X496, which outputs 22w RMS. In combination with these speakers that are closer to 3.5 ohm actual, this system outputs quite a bit of sound. In my opinion this is the best sound I've ever heard out of a system with no sub and no external amplification!

It depends on the CD but the one quality that I could possibly see people having a problem with these speakers is if you are listening to anything with a very bright sound you will need to attenuate the treble a bit.

Pros: Incredible sound.

Cons: Have to do some minor extra work to install in 2003 Civic Sedan.

Love em!

Crutchfield Customer Review (What's this?)

Fitted to a 2009 WRX 5dr hatch. Installed these matched with the factory base stereo and they sounded awful but that was to be expected as they were under powered. I then swapped in the upgraded factory stereo that puts out more power and they really came alive and sound awesome. I plan on getting an external amp to run these and hope that wakes them up even more.

Price on Crutchfield was a bit expensive compared to other online retailers, but after you figure in the free shipping, free mounting rings, and wiring adapters you come out pretty much even.

Pros: Sound great

Love These Coaxials

Written By DwayneG, Silver Spring, MD on Monday, November 22, 2010

Crutchfield Customer Review (What's this?)

JL Audio has the best coaxials out there. I got these JL Audio C2-650x coaxials installed in the rear deck along with the JL Audio C2-650 component speakers installed in the front and they sound amazing. Well worth the money. I'm now a JL Audio fan for life.

Best coaxial

Written By James, Indiana on Saturday, June 26, 2010

Crutchfield Customer Review (What's this?)

Fit my 2010 Tundra with scosche speaker adapters even though not listed as fitting by crutchfield. Great sound. Smooth sounding tweeter. The woofer and tweeter are well balanced. Handle high power. Have mine running off a JL Audio 900/5 HD amp and love the setup. Can't go wrong for the money.

very happy with results

Written By Jeff, Des Moines, IA on Friday, April 16, 2010

Crutchfield Customer Review (What's this?)

I purchased these speakers to replace the factory GM speakers in the door of my RV that is built on a Chevy Express 3500 chassis. The dash stereo has these two speakers and that is it. I am very happy with these speakers. They fit precisely, just as Crutchfield's tool said they would. The speaker wiring harness was a nice touch from Crutchfield, allowing me to easily switch these out without modifying the wiring at all.

There is a very large difference between the factory GM speaker and these. The factory speakers were basically giving me mid-range and that was it. These speakers have much greater range. I can hear the bass now where before it didn't even come out of the factory GM speakers. As I cycle through the EQ settings of my JVC in-dash stereo, I can actually hear the changes. Before, as I cycled through the EQ settings with the factory speakers I basically heard very little change.

The only thing that I wonder is if these were worth the price. There are many other 6.75" speakers available that also get high reviews for $80, $100, $125, etc. I wonder if I would notice any difference between them and these? If I forget about the price that I paid for these, then I am very happy.

Exceptional

Written By MrCrispie, Hays, KS on Wednesday, January 20, 2010

I am a self proclaimed audiophile with medium-budget tastes. I like bang for my dollar. I started out with full Alpine Type-S speakers in my Mitsubishi Eclipse, and was pleased with the full-spectrum response i received from them for months. I am still using the Alpine MRP-F300 4 channel (50W X 4) amp with my new JL C2-650x speakers. They are in the doors as well as in the back. When I installed them, I installed one speaker in the back and left one Alpine Type S in the other side, set my Headunit to isolate each speaker, to hear the difference. Night and day. I am a stickler for midbass response and mellow tweeters that don't pierce my ears. At high volumes, there is no distortion across the board (heavy metal, hip hop, rap). I know people are wondering how these things perform across all genres of music...I have played them to their fullest extent (after the break in 4 hours) and cannot make these things budge from sounding absolutely phenomenal. The midbass surprised me. They hit clean, distortion free, and hard. If you are looking for a speaker that shines across all volumes, is clear, exceptionally clear, very very mellow flat tweeter response (no shrieks, no brightness at all) , look no further. JL has produced some of the most amazing sounding speakers in its C2 line. I am hard to impress. These impressed me.

All plastic one size fits all bracket. Two sets of spots to screw in speakers depending on which size you get. What I didn't like was for the smaller size it had metal clips to screw through to reinforce the holes but for the larger size there were slots instead of holes and no metal reinforcements for them. Seemed not the best but was free. I plan to reinforce the screws more with some epoxy next time I open my doors to put in dynamat. [ John  May 18, 2014 ]
Hi! I'm not really sure what you are asking. I will be glad to help. What bracket are you referring to? And the what size are you referring to? I out these in a jeep wrangler and used the existing holes and made new ones. Maybe a little more custom than you might want to do. Ask me anything and I will try to answe the best way I know how!
