The best way to listen

JL Audio's Evolution™ C5 premium full-range speakers reproduce your music with impressive fidelity and power. Your music will sound smooth and balanced, from the splash of a cymbal to the thump of an electric bass, and everything in between.

JL Audio's C5-650x 6-1/2" speakers feature long-excursion woofer cones that travel farther and push more air than normal woofers, putting more oomph in your music when the rhythm section kicks in. The frame assembly utilizes a patented cooling system, which increases efficiency, power handling, and long-term reliability. The fluid-cooled silk dome tweeters combine with the woofers to create a well-defined and stable soundstage, almost like having a live band inside your vehicle.

Unlike most full-range speakers, these Evolution™ C5 speakers use external crossovers that feature 4-position tweeter level and 3-position midrange presence controls. You can tailor speaker output to suit your listening preferences and to compensate for your vehicle's acoustics.

JL Audio C5-650x

I purchased these speakers (JL C5-650x) along with some Focal EC 165K2 at the same time. I have two Camaro's which I put each set of speakers in both cars along with Alpine PDX F6 amps in both cars as well. Both are awesome sounding speakers, but I finally favor these JL's because they are a bit warmer and natural not as bright as the Focal and the low end frequency response of the JL's are 48hz vs 60hz on the focal, which is a noticeable difference in delivering lower clean bass notes.

Perfect pairing for the C5-650 fronts!

Definitely one of the best speaker purchases I've made. I had upgraded the stock speakers once before to an entry level Infinity set I took off an old car; component fronts and coaxial rears. I also hooked up a small Alpine KTP-445u amp and was content with what I had a the time. Then I bought my wife a new car with a much better stock system. I just had to upgrade my sound system now. Unfortunately, the market just isn't want it used to be but JL Audio still provides some stellar products. I gave myself a good budget and started looking. I considered other manufacturers and also looked at JL's ZR series but really do prefer the sound of silk dome tweets. I bought myself two sets of JLs; component C5-650 fronts and C5-650x coaxial rears. I can't say enough on the build quality. However, these speakers are deeper and bulkier than my old speakers, so the install took a little more work. In a nutshell, I had to modify all the door panels and come up with some custom spacer with the supplies provided. Nothing too difficult. I ran the speakers for a week with the smaller Alpine KTP-445u then finally found time to properly wire the JL MX500/4 amp I bought with the speakers. It is night and day difference! DO IT! Buy a good amp. The mid-bass isn't car rattling but completely satisfying IMO. There's also sounds in my music I've never heard before and am finally experiencing it for the first time. Did I say AWESOME speakers?

Pros: Provides satisfying bass. Everything I've wanted from a full-range speaker.

Cons: External crossover (for those who are limited with space)

Ordered these for my 2008 Jeep Wrangler sound bar. They were not recommended to fit in my case, but fit perfectly. (I did use the Jeep Wrangler speaker adapter rings.) Was looking for something to cut through the wind noise as here in Texas we can go most of the year with the top down and I practice this faithfully. These speakers do this with ease at freeway speeds and deliver plenty of smooth balanced tone at top volume.

Pros: A joy to listen to, and look forward to listening to them on the ride home from work each afternoon.

Cons: None so far.

Pros: Sound quality !!!

Product Research

Crossover Features


Cast Alloy Baskets: The C5-series coaxial speakers feature cast alloy woofer baskets, while incorporating JL Audio's patented "Elevated Frame" cooling system. This cooling technology, also found on the flagship ZR component systems and W7 and W6v2 subwoofers, allows air to flow directly across the top plate and onto the voice coil windings to greatly improve linearity at all listening levels.

Motor Structure: The DMA (Dynamic Motor Analysis)-optimized motor structure achieves outstanding linearity.

Size Classification Note: Some manufacturers, including JL Audio, call this size speaker a 6-1/2". Because it requires a larger cutout than a standard 6-1/2" speaker, Crutchfield has traditionally referred to this size a 6-3/4". Please enter your vehicle information to confirm fit.

Woofer Cones: The cone and suspension elements were designed and manufactured by the world-famous Dr. Kurt Müller & Co of Germany. The speakers feature low-mass, mineral-filled polypropylene cones with butyl rubber surrounds. The cone and surround are inherently well damped to deliver an uncolored, neutral midrange without any coloration. The speakers are also equipped with symmetrical-roll, hybrid-weave spiders.

Silk Dome Tweeters: The C5 coaxials' 3/4" silk dome tweeters are incredibly smooth on- and off-axis for accurate imaging and a big, stable soundstage.

Power Handling: JL Audio publishes several power specifications for this speaker, 75 watts continuous power handling (RMS), 225 watts peak music power, and 25-150 watts recommended amplifier power (RMS). We've listed the conservative combination of 25-75 watts RMS in the specs table.

Crossover Features

Two-way Crossover System: The C5 coaxials utilize the same true 2-way external crossover system found in the C5-series component speakers:

  • High Pass: On the tweeters is a second order high-pass filter utilizing premium Mylar capacitors combined with an air-core inductor. Four tweeter level settings are selectable via jumper pins: +2.0dB, Reference, -1.5dB, and -3.0dB.
  • Low Pass: The low-pass section features a first order filter with three levels of user-definable midrange presence: Low, Reference, and High.

Polyswitch: Polyswitch tweeter protection is incorporated into each C5 coaxial crossover network. It monitors current going to the tweeter and will disconnect the tweeter from the signal when it senses overload. Once the volume has been reduced, the protection circuit will reset itself automatically.

Barrier Strips: Connections to each crossover network are made via protected nickel-plated barrier strips.

Crossover Dimensions:

  • Length: 4.72"
  • Width: 3.367"
  • Height: 1.44"

Connection Note: The C5 coaxial speakers come with no speaker wire. Instead, a number of spade connectors and quick slides are included in the hardware pack to be crimped onto speaker wire you provide.

I have a pair of JL C5 650X speakers that I am powering off of a Rockford punch 150 and want to put a sub in the trunk . The vehicle is a 1960 Chevy impala convertible. I am locating the JL C5 650x in the front lower kick panels where the cold air vents are located. What type and How big of a sub can I run on this punch 150 and this pair of JL Audios ? Thanks
