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 C2-525x, specifically, has a respectable frequency response of 63 Hz - 22,000 Hz, continuous-power handling of 60 watts, and a solid efficiency of 89.0 dB, giving it the ability to produce smooth mid-range and highs.

Good bang for the buck

Great quality, great product. Sounds awesome with outstanding clarity.

Great Sound for the buck!

I am usually a component style guy, but for my auto had no choice but to get coaxials. I am happy I went with these JL Audios -- great mid/highs. Not heavy on bass as expected on coaxials but proven winner for clarity!

Best 2-way speakers out there!

Never have I heard such amazing bass response and lifelike highs from a 2-way speaker. Makes my old Alpine Type-R's sound like crap. If you want the best possible sound and can't get components these are your next best option.

Good alternative to component speakers

These were a bit of a splurge but I think it was worthwhile to buy them. These speakers are a good answer for someone who wants to get quality lows, mids, and highs from a coaxial speaker pair. I did not want to get into high end component speakers and I am very satisfied with these. I mounted them in the rear roof of my 2000 Jeep Cherokee. They are powered by a 50 RMS x 4 Alpine amp. Previously I had some Polk Audio speakers for which I had to set the crossover at 80 or 100 so as not to distort. For these JL C2-525x's I don't use the crossover at all and I get no distortion at the same gain level I used with the Polk's. I was surprised by the quality of the lows the JL's produce being such a small size. My only suggestion to JL would be to have built them with screw down type of wire connectors.

Smooth Sounding

JL audio speakers will always be included on my list of speakers to consider for any future car audio system. Nice mid range, and the tweeters are impressive. I expect no low end from 5 1/4's, but these surprised me. They will not make you give up on your sub, but they do go lower than you expect. Great speakers.

Great Speaker!!

Fantastic sound for a great price.

These jl audio coaxial speakers were installed in my BMW and they sound amazing. For the price it's hands down the best equipment you can buy. Every aspect of these speakers is perfect. The mid bass is tight and highs are clear.I would recommend this product for anyone looking to upgrade their sound system.
