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 C2-600x, specifically, has a respectable frequency response of 59 Hz - 22,000 Hz, continuous-power handling of 60 watts, and a solid efficiency of 90.5 dB, giving it the ability to produce smooth mid-range and highs.

Good Speakers

These are decent sounding speakers. The highs are clean. The mids are pretty good too. The mid-bass is ok. The bass response, is expected, isn't there (if you want good bass, buy expensive, high quality speakers... if you want good and deep bass, buy a sub). Overall: I recommend these speakers. They are good enough sound quality for the price range.

Decent sound from a small speaker

Direct fit in the factory door opening of a 1979 Ford F-150, no mods required. Sound quality is good even though it is powered by an OEM AM/FM radio that is 30+ years old.

Great speakers for low price!

These speakers deliver clear audio. The base tones are clearly distinguishable from the high and medium ones. The power they pump is more than adequate to fill a medium vehicle. I have mounted on a Honda CR-V 08 and the difference from the stock speakers is remarkable. I'd recommend these speakers over some other brand not only because of their sound but their quality--i.e., I've never seen any other speakers with their magnets insulated with a high quality rubber. Just because this fact alone make the JL Audio speakers a winner in my book!

Outstanding upgrade. Great experience.

I purchased these speakers for the front doors in my 1994 Bronco. I wanted a really great set of speakers that were a solid upgrade over the JBL's that the previous owner installed which had begun to malfunction. I wanted something with nice bright highs and full mids that would take plenty of power. At this price, these went above and beyond my expectations. The coax is also super easy to install. Overall an outstanding easy upgrade to my Bronco. Sonic Electronix was extremely helpful, had the best price, and took excellent care packing and shipping my order.
