JL Audio Evolution C2 Coaxial 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. The 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 coaxial 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 C2-650x, specifically, has a respectable frequency response of 59 Hz - 22,000 Hz, 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.

Excellent Choice

I installed four of these in my wife's Toyota 4-Runner to replace the OEM speakers. The sound quality is impressive to say the least. The only equipment powering them is a JVC KW-XG700 with no external amp. As already stated here, the quality of these speakers is excellent, complete with rubber cover magnets that are huge. After installation was complete I performed the "how much can they take test" and was impressed at how loud I was able to crank it before the sound quality degraded. Bass is outstanding for speakers this size and the highs are nice also. These are a great choice if you're looking for a nice improvement over your factory units.

Nice sounding value speaker

I'm powering these speakers off a Pioneer P4000DVD and they sound very good for under $100. I had to set the high pass filter at 80hz but that is pretty typical for running off a deck.

If you want bass, I would avoid these. You should have a sub or at least 6x9s in the back to complement these speakers.

decent speakers for the price

replaced rear factory toyota speakers with these. huge difference in sound quality and distortion/volume. used with scosche brackets for 6.5s and metra wire adapters. install wasnt too crazy. pleased with the purchase; it was either these or Alpine Type Rs. powering them with an Alpine ktp445u and they complement my dual 8 inch JL W3 ported enclosure very well. if your looking for good speakers and working within a budget, go for these. if you can spend a little more, id go for C3's or C5's (if you can amp them).

Great speakers!

These are some of the best speakers I've heard--ever! They match up all the frequencies very accurately. They're rated at 100 watts max. only but if you have a head unit that pumps 50 watts X 4 (@ 20 watts RMS, give or take), these'll be perfect for you. They're rated at 60 watts RMS, so pretty much any HU that you match them up with will do the job nicely. However, if you're planning on hooking up an amp you're probably better off getting something else (i.e., Infinity Kappa), since these babies pump up 91 dB with the head unit alone! I actually replaced a pair of Kenwoods for these ones because of their better quality of sound--and I was not disappointed. The manufacturing quality is also remarkable! I've never seen speaker magnets all covered with rubber. They're still 6" even but JL Audio makes a 6.5" also of the same specifications, which might fit some cars better.
