Product Details

JL Audio Evolution C2 6-1/2" Coaxial Speakers - C2650X

For a car speaker to excel it must be thoroughly engineered in all areas. The woofer design must deliver sufficient efficiency, smooth mid-range response and good low-frequency extension. The tweeter must be smooth off-axis, exhibit good extension and be non-fatiguing, while the crossover design must seamlessly blend the sound of the drivers so that the end result is clean, realistic audio performance.

In designing the new C2 Coaxial and Component Systems, we have drawn from our vast experience in woofer design as well as the tweeter technologies employed in our world-class C5 component systems. The resulting products deliver a compelling performance solution at a price within reach of any enthusiast seeking a great listening experience.


  • Killer Bass
    It starts with ample mechanical clearance, optimized suspensions and balanced motor designs. This allows us to use longer voice coils that let our speakers move further for enhanced output and lower frequency extension, something that weaker designs can’t do without exposing their inadequacies. We also avoid certain “pitfalls of convenience”. For example, we make a separate 6-inch and 6.5-inch model… because designs that attempt to cover both sizes compromise suspension travel and linearity.
    But, you don’t have to take our word for it… fire up a pair of C2’s with some good clean power at your local dealer and listen to music with solid, intricate bass content. Then switch to any other speaker in the same price class. It’s not going to be a subtle difference.
  • Silky Smooth Tweeter
    Ahh, the tweeter… everybody has a story about their tweeter. You hear crazy things like “unobtainium dioxide, vapor deposited by elves onto a specialized polymer”. Then you listen to it and it sounds like needles piercing your eardrums. So much for painted plastic tweeters, then.
    In fine home speakers and studio monitors, one tweeter material and basic architecture is used above all others, and for very good reasons. A well-designed, edge-driven silk dome is smooth, detailed (on or off axis), and very hard to beat in terms of overall performance. Silk is about as lightweight as it gets (good for high frequency extension and efficiency), is very well-damped (doesn’t ring like a bell) and thanks to nature’s magic is also extremely durable in the automotive environment.
  • Loud and Clear
    It’s not terribly difficult to make a speaker that sounds pretty loud in the midrange. This common approach leads to speakers that grab your attention at first (loud tends to do that), but ultimately sound harsh and fatiguing during extended listening sessions (because the loudness is not evenly distributed).
    Smoothness of response and freedom from excessive distortion are the factors that truly matter in creating a speaker design that reveals the inner detail of your music, making them enjoyable for years to come.
    Making a speaker that can play loud without sounding harsh is what separates the men from the boys. So, we focus on creating low-distortion motor and suspension systems, as well as carefully engineered cones that deliver the right combination of stiffness, damping and off-axis response. If you didn’t understand a word of that, don’t worry… you will hear it, loud AND clear when you audition a C2 speaker system.
  • Stylish Grille Design
    All models, except the C2-350x and C2-570x, include front-loading protective grilles with a striking new design that combines black steel mesh with satin silver accents. Electroformed logo nameplates can be positioned on the grilles or elsewhere in the vehicle, according to the needs of the installation.

        Comments about JL Audio Evolution C2 6-1/2" Coaxial Speakers:

        I have installed many coax speakers over the years, and this was my first time using JL products. I knew of their excellent reputation so I felt my money was being well spent. These are not the cheapest coax's out there but I think they sound great compared to some speakrs I've used before that were only marginally cheaper.

        Everyone has different expectations of what sounds great though, so they may not appeal to everyone.

        Replacing just about any factory speakers with these will be a noticeable difference, as they were for me. The clarity, and clean sound, even at higher volumes keeps me smiling when in my car. The tweeters to me are never harsh, and I only find the bass to be a problem when the music gets close to it's crossover point and is asking a 6.5 to behave like a subwoofer, but this is rarely. A small adjustment on the crossover is all you need to make sure you don't over tax the speaker. I am running my system off of my factory head unit, so if you can run your system from and after market head unit with more precise control over the input quality, you should notice even cleaner sound, especially at higher volumes as factory head units often add eq curves to help factory speakers sound better.

        After a break in period you will notice the speaker does mellow a bit and seems to take the clarity to a little higher level, not to say it can compete with some of JL's or other brands top tier products, but for the price, they are hard to beat.

        They are a great match to JL's XD line of amp, which are great amps to begin with, and I find they sound great together. I have at the moment a Kenwood KAC1502S running my rear channel door speakers, and notice quite a difference in the output level, noise in the signal, even with the Kenwood being fed through a line output converter while the JL is fed speaker level inputs.

        If you are unsure of spending the extra money to step up to the JL's, be super gentle with them and try them out for awhile, returning them if you're unhappy should not be a problem with a company like Abt.
