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. 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 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 C2-525, 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.

JL audio C2-525 review

I recently purchased a pair of JL audio 525 speakers wit tweeters and components and the sound better than the mtx I had. But they are plenty loud if u like to blast ur music like me ur ears will be ringing a little. Tweeters were kinda hard to position but it was my first install so that mite be it also. All u need is the extra wire which u could get at any electronic store. Good buy for me. I also shopped around a couple of other sites to see who has better prices and these were the guys. I'm waiting for those DVD decks to go on sale. They r still really pricy.

Awesome sound

I bought these and installed in my 2017 Jeep renegade. I was hesitant on component speakers, due to my inexperience with installs, but decided to roll the dice. Very happy I did. They were actually pretty easy to install and the sound coming from these is pristine. I have them hooked to amp only pushing 40 watts RMS per channel, but even underpowered they are amazing. Going to upgrade amp to bring out the full potential soon. I recommend for anyone wanting highs and mids to sound clean and clear.

Great Speakers!

I have had these speakers for over a year and I'm extremely impressed with their quality and sound! Crossover is a little bulky so hiding and I stalling takes some creativity but would highly recommend these speakers!
