JL Audio Evolution C3 Series Convertible Component/Coaxial System

With the Evolution C3 Convertible Systems, the same product can be deployed in either a Component or Coaxial configuration, delivering outstanding audio quality in each application. Long woofer excursion capability with DMA-optimized performance delivers superb mid-bass and clean mid-range output, while the powerful 1-inch (25 mm) silk dome tweeter delivers brilliant high-frequency performance. The tweeter is very special in its own right, it is a pure silk dome edge driven tweeter, which makes it larger than traditional OEM tweeters, and it allows it to player louder and with better fidelity . The woofer houses a beefy 1.2-inch voice coil that generates a stunning mid-bass output without sacrificing mid-range fidelity. In addition, the woofer offers a mineral-filled polypropylene cone, a rubber surround, and an injection-molded polymer basket.

Silk Dome Tweeter

Silk Dome Tweeter

JL Audio C3 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 Linearity and Control

JL Audio Linearity and Control

DMA is JL Audio's proprietary Dynamic Motor Analysis system and is aimed at improving dynamic motor behavior. As a result of DMA optimization, Evolution C3 motors remain linear in motor force over an extreme range of excursion and also maintain a highly stable fixed magnetic field in the gap over a wide power range. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate low end. Its main catalyst is the driver's robust 1.2-inch voice coil, that allows extreme linear excursion, phenomenal power handling and control, control, control.

Very nice

I definitely recommend these speakers. I have used less expensive component speakers in the past and these are far superior. Solid construction and outstanding sound. The high frequency level adjustment selection is easy to move and lets you tune the highs without equalization on the input to the amp. I have the JL Audio 300/4v2 driving these which helps the sound, but overall they handle the power well. Interesting configuration option to mount the tweeter on the bass driver similar to a coaxial speaker.

Looks and Sounds Great

These are in my Kick Panels in my 87' R10/C10. They match up with the stock interior and improved the overall sound quality tremendously.

Descent Speaker

Pretty good speaker for the price. The best part about these is the fact they are convertible. I have found when you really start driving them the tweeters start to break up. But possibly I don't have enough power going to them. I run a kicker 1000.5 and use all five channels.

Great sound... But the tweeters are loud and crisp almost in your face... If u have a lot of bass it blends in nice...

Awesome sound, Great Product, Phenominal Experience!

I have two pairs of the C3 650's in my Nissan 350z and I love them! At first I was considering the C2 650's but once I heard these over them I knew right away the C3's were 10x better then the C2's. Don't get me wrong the C2's are good too but these just have cleaner sounding highs and mids. They can get pretty loud because of this however it will not sound nasty crackling loud it will definitely get you noticed in the way that you want to be noticed and not in the way that you don't. I also compared the C3's to the C5's and honestly I chose this over the C5's because for one the C5's are almost $100.00 more per pair and two they only sound a teeny tiny bit better that's all! By better sounding I mean the high's are not as loud as the C3's so it doesn't fatigue your ears if you listen to them at high volume for extended periods of time. I run 4 C3 650's in my car along with 2 10W3V3 subs in a stealthbox and a 900W Kenwood amp to power them all up and my car sounds like I'm front row in a concert of whoever I am listening to at the moment. 5 stars on these speakers JL great job! 5 stars on my whole setup about 80% JL product. Don't believe the "overpriced" crap. Yeah they run a bit on the expensive side but their products are so worth it, you get nice clean LOUD quality sound. Something most brands can't offer, it's either SPL or SQ.

I got these speakers as an open box item but they looked brand new. One thing I can say is I replaced some Polk speakers with these and I haven’t stopped grinning since I had them installed. Oh, I had a great experience with Sonic Electronix
