Our take on the JL Audio C2-525X

by Buck Pomerantz
JL Audio

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

JL Audio's Evolution C2 speakers

Side view of Evolution C2 speaker JL Audio's Evolution C2 speakers bring precision sound to your vehicle. They'll reproduce subtle elements of your music like delicate woodwinds or soprano vocals, then turn on a dime to deliver the deep thrum of the bass or thunder of the drums.


Silk tweeter delivers smooth highs

Silk tweeter

The C2-525X 5-1/4" speakers feature rugged polypropylene cones with rubber surrounds that can handle high power without distortion, so you get full-bodied low tones you can really feel. The 3/4" silk dome tweeters serve up smooth-sounding high frequencies that won't tax your ears, adding a satisfying dose of realism to your soundstage. Built-in crossovers make sure your tunes play smoothly across the whole musical spectrum. JL Audio includes a pair of grilles that you can use for custom installations.

Features

Woofers: The JL Audio Evolution C2-525x coaxial speakers feature a 5.25" injection-molded, mica-filled polypropylene cone woofer with a butyl rubber surround. The woofer features a 1.0" voice coil on a Kapton Former, a symmetrical roll spider and a Ferrite magnet. These carefully engineered cones deliver the right combination of stiffness, damping, and off-axis response. The speaker also provides adequate bass, thanks to its ample mechanical clearance, optimized suspension and balanced motor design.

Tweeters: The Evolution C2-525x coaxial speakers feature a 0.75" silk dome, ferrofluid-cooled tweeter with a damping neodymium magnet. The well-designed, edge-driven silk dome tweeter is smooth, detailed (on or off axis), and provides great overall performance. Silk is lightweight and great for high frequency extension and efficiency. It is also designed for durability in the extreme automotive environment.

Grilles: The Evolution C2-525x coaxial speakers 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.

Some Good Little Speakers

Written By PittbossTx, Arlington, Tx on Thursday, June 20, 2013
Crutchfield Customer Review (What's this?)
 
These are some excellent little speakers, being only five and a quarter inch. They installed easily into a 2013 Jeep Wrangler Rubicon in the soundbar location. Crutchfield provided everything I needed for a smooth installation. I bought these open box, and I could not tell they were not brand new.
Pros:
Blow the factory speakers out of the water
Cons:
None

nice sounding speakers

Written By Anonymous, tulsa, ok on Wednesday, October 17, 2012
 
Great sounding speakers, but in my opinion, my alpine type r's awesome sound kinda put these to shame.
Pros:
Nice crisp highs
Cons:
You will probably need an amp to hear them over your rear speakers.

awesome 2-ways

Written By dr, akron Ohio on Sunday, July 15, 2012
 
I put these in the rear doors of my 2011 Nissan xterra. I can't testify to how they hold up as main speakers, but as "filler" they go above and beyond. excellent value.

Great Speakers Jeep's not quite plug and play

Written By Mixerbd699, Wichita Falls, Tx on Sunday, July 08, 2012
 
Great sounding speaker, handels power real well and has great quality.
Pros:
Great sound quality, and power handling, pretty easy install
Cons:
Jeep wrangler owners will want to be ready for some extra install steps. I had to drill two of the 4 holes on the sound bar. Other than that its a breeze to get them in.

Wayyyy better than Type Rs

Written By Kyle, Naperville, IL on Monday, March 02, 2009
 
I just got a new car (98 Toyota Avalon XLS) and I've been going all out as I've started from scratch with my audio system. These speakers are wayyy better than the 6.75" Alpine Type Rs I had in my old car. The magnet is huge and the bass is unbelievable, this is matched equally by the not-to-harsh treble. They seem to be built tough with a rubber protector on the magnet and an incredibly solid feel. This was my first time experiencing JL Audio and I must say, it wont be my last.
