JL Audio Evolution® C2 Component Speaker System
JL Audio Evolution® C2 Component Speaker System

JL Audio Evolution C2 speaker systems deliver an impressive audio performance solution and value. The technology of the Evolution C2 Series has been drawn from JL Audio's experience in woofer and tweeter design. They have been engineered to deliver adequate efficiency while retaining a smooth mid-range response with low-frequency extension. Smoothness of response and the freedom from distortion are factors that make the C2 Series speakers truly one of a kind and enjoyable for everyone, and the resulting product is one that delivers performance for any car audio enthusiast at a price that won't break the bank!

Silk Dome Tweeter

JL Audio C2 tweeters incorporate silk dome diaphragms to deliver smooth high-frequency transitions, on and off axis. Silk is a natural material with inherently good characteristics as a tweeter diaphragm. In addition to being very light in weight, silk exhibits excellent damping properties, which reduces ringing and resonances in the tweeter’s passband, leading to a smooth, pleasing high frequency character free from unnatural sibilance or exaggerated brightness. This is why a Silk Dome Tweeter is preferred by many audiophiles for its overall balance.

JL Audio Quality, Build and Design

JL Audio Evolution C2 component speaker systems feature mineral-filled polypropylene cones, long excursion capabilities and stamped steel frames. In addition, the woofer design benefits from JL Audio's vast woofer design experience and advanced modeling systems. It is this use of proper high-quality components and advances that allow the speaker to perform better than any other speaker in its price range. The C2-650, specifically, has a respectable frequency response of 59 Hz - 22,000 Hz, a continuous-power handling of 60 watts and a solid efficiency of 91.0 dB, giving it the ability to produce smooth mid-range and highs.

purchaesed these along with the coax C2 in winter 2010 and rewired my entire car through a audiocontrol LC7 (which i love) and powered them up after two days of work. they fired up with no issues but I noticed something weird after 3 or 4 days of mid level listening... the tweeter would decrease its volume and it would sound like crap. I like to listen to my music fairly loud but the tweets couldn't take the power from my amp. compared to some other speakers the mid bass is lacking as well. needless to say i have disconnect the tweets and the mids sound like crap.... be very cautious or at least dont give'em too much power.

Great speaker! Completely happy with my purchase!

About 8-9 months ago i decided to put a new HU (Pioneer AVH-3300Bt) into my 2005 tacoma with no expectation of purchasing anything further car audio wise. After I installed the HU my stock speakers improved by quite a bit! Which made me wonder what would a decent pair of aftermarket speakers would sound like?!? Well after hours of scavenging the internet and going to local car audio shops i decided to get these (C2-650) for the front and the C2-650x's for the rear.

Because these speakers are a bit over sized (6 3/4) and have 6X9's up front i had to purchase speaker frames/mounts so they would fit into my doors enclosures. Once I had the mounts and the frames i went ahead and did the install. First thing i notice was the nice crisp highs from the silk tweeters while the speakers external crossover was set to neutral. None of that metallic "tis tis tis" tinging treble. I played around with the -3 +3 settings as well but thought 0 was right on!

I was running the speakers from my HU at what Pioneer said was 22 watts RMS but is probably closer to 12 watts per CEA Compliance. But it did not matter! The speakers sound as good as one could expect from such little power. They produced ample amounts of bass, mids, and highs!!! Now, don't get me wrong. I was not rattling my mirrors uncontrollably or anything but the speaks did a good job from low frequencies to high from HU power.

Well I could have settled with what i had seeing as I am not 18 y/o anymore and am not looking for anything other than nice crisp clean well rounded audio. But now that i had replaced my HU and speakers I couldn't resist purchasing an amplifier (Arc Audio KAR 400.4, 50w RMS X 4, but from what tests have shown Arc under rates their specs and is probably closer to 70w RMS x 4 at 4 ohms).

At the same time i purchased sound dampening material because even with the speakers being power through the HU it was causing things to rattle :-(

Installation of the amp and sound dampening material made a HUGE difference! Man those speaker hummed for the $$$. Now my mirrors were starting to rattle... okay just a little :-) Sounded good at all volumes and when eq properly almost made me think i didn't need a sub.

Yeah, of course... I decided to purchase a sub next ;-) (LJ AUdio 8w3v3-2) and ran the front and rear 6 1/2's in parallel from the amps rear channel's and the sub off the front bridged. I know not the best way to do it but working with what i got. So now with the speakers in parallel and a sub playing with them properly equalized my system is complete!

Long story short every which way I had these speakers set up they sounded great and am 100% happy with. This is not my first stereo and have tried out plenty of other compairable price wise speakers and setups and this is by far my favorite. Of course you could do better if you wanted to spend more but for the price these are above average and perfect for me!

Great sound

These speakers sound great. Good mids and highs. These speakers just keep sounding better everytime I hear them. JL all around from W7,1000/1. Perfect match

great clean sound

Great speakers can hear them very well in my 65 AC Cobra, over the wind and engine noise. I have JL amp (J-320.4) driving them and an iPod.

Great Sound-- Even Better Price

I have always been a fan of JL Audio products, and once again they proved to me that they can offer great performance speakers w/o having to break the bank.

not bad, noticeably better than factory

not an audiophile by any means, but i do appreciate a good ratio of sound quality to general loudness...frankly, i wanna blast my music and drive out road noise without having distortion, clipping, harsh tweeters, good mid-bass, etc. these speakers are great. powering them with an Alpine ktp445u (probably wouldnt recommend these comps without an amp)...first time installing comps, wasnt too crazy. the 3/4" tweeters snapped right into the factory tweeter locations with no modification. these do sound much better than my factory "pioneer" comps, but knowing what i know now, i think id go for C3 or C5 comps...dont get me wrong, these are good. the tweeters do clip sometimes at high volumes as others have commented, but that may or may not have more to do with how i tuned (or neglected to properly tune) my system than with the actual speakers. doesnt happen often and is usually remedied by consulting the volume knob...these get loud, play well, complement C2 coax in the rear doors and two 8 inch W3 woofers in the trunk very well. overall im pleased with them, but like i i just want MORE haha. perhaps C3 or C5s in the future. on a downside, these were made in China, as im sure all C2 sets are, which speaks for itself -unless you dont care about that sorta thing. good if your on a budget, better with an amp. i recommend for the price, but if you can, go for a higher end set

awesome and precise

This component set is everything I expect out of jl audio the sound reproduction is amazing compared to the coaxial I had prior to these. Also sonics price is well worth the money they are as most components not as loud as coaxials but for a person buying components they are looking for clarity which they do and do well. Don't get me wrong they are loud without a doubt just in a different way

Very Good For The Price But Not For High Watt Systems

Overall I am very happy with these. I had a set of JL XR's in my old car which I loved and that is why I bought these. Very clear and GREAT bass response. Had to cut mid bass driver surrounds to install in a 2006 Grand Prix GXP, a spacer may have also worked, but depth wise they fit no problem.

Now What I Don't Like:
JL has put tweeter protectors in their Cross-Overs. This results in the tweeter dropping out from time to time. VERY annoying and makes one think there are other issues. If you are driving these with more the 75 Watts RMS you will probably experience this (I am at 110 watts RMS). It is possible to remove the protection device however they add a little resistance to the tweeter's cross-over so the highs might be a bit brighter than before. Another option is to run the tweeters at -3db or even do both. I am considering upgrading to the ZR tweeters to solve my issue as the tweeter sounds stressed when pushed. At mid volume they are VERY smooth and detailed.
