JL Audio Evolution® C3 Series Convertible Speaker System
JL Audio Evolution® C5 Series Coaxial Speaker System

Evolution™ C5 is serious product, engineered by JL Audio to meet the demands of the toughest acoustic and environmental conditions in the high-fidelity world. It is not about cute buzzwords or the exotic material of the month... it's all about making your music come alive with realism and excitement. C5 woofers and tweeters are precision-built in Germany alongside JL's flagship ZR components, incorporating their exclusive DMA-optimized motor and patented Elevated Frame Cooling technologies. Particular emphasis has been placed on off-axis response and dynamic stability which might not be that important during a five minute evaluation on a demo board, but makes all the difference when installed in your car. The system is comprised of high-end silk dome tweeters, die-cast alloy baskets, and renowned Kurt Müller designed cones and suspensions. In addition, C5 crossover networks are compact and built with premium component parts, including Mylar® capacitors and segmented air-core inductors. Four levels of tweeter attenuation are provided, as well as three levels of mid-range presence adjustment, for twelve possible voicing combinations! The combination of these components provide smooth and transparent audio for the true Audiophile!

Silk Dome Tweeter

Silk Dome Tweeter

JL Audio C5 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. The small size of the tweeter minimizes tweeter protrusion, allowing it to easily fit behind most factory speaker grilles.

JL Audio Linearity and Control

Unparalleled Build and Precision

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 C5 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. In addition, JL Audio turns to their partners at Germany's Dr. Kurt Müller & Co. for critical cone and suspension elements that provide unparalleled woofer performance.

Speaker Specifications

This is the manufacturer product line of speakers.
Evolution C5 (JL Audio)
Priced Per
Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
5" x 7" (also mounts in most 6" x 8" locations)
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
Tweeter Design
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
Tweeter Composition
Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Mineral-Filled Polypropylene
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Butyl Rubber
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
225 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
75 watts
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
90.5 dB
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
48 - 25,000 Hz
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
5.47 x 7.68 
Speaker Grilles
A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.
Number of Speakers
This is the number of speaker that is included in the package. Each purchase will result in receiving the number of speakers indicated here. Please note that some items will have multiple woofers in the same enclosure. For sets of component speakers, this number will refer to the number of sets of speakers (For example, 2 would indicate the purchase includes 2 woofers and 2 tweeters).

Please refer to the product image and description for further details about the speaker.

Nice sounds!

December 1, 2010

In a world of all things Made in China I chose to purchase the JL Audio C5-570x because they are not!! They do cost a bit more than some other brands of speakers but I got them for less at Sonic Electronics.
The JL's are installed in the front doors of my 2010 mustang I also fully Dynamat ed both doors a good thing to do.
Powered by the factory radio for now the music is clean, smooth, with more detail and at higher volume there is no distortion I am very satisfied with these speakers.

Simply awesome!

August 30, 2013

If you're looking for a great speaker go for these JL's. I'm a live sound engineer and have mixed a lot of music so I thought it would be very hard to reproduce in a car what I'm used to hearing on stages. I have been nothing but impressed with the quality of these speakers. You hear the music like its right there with you. All genres sound great. Only thing is they are a bass heavy speaker if you have a sub no reason to have that bass in the doors in my opinion, I want to save that room for mid and higher frequencies. So on top of my door crossovers I set my amp crossover to 100hz. The active crossovers the speakers came with were just not cutting out as much lower end frequencies as I prefer. Overall I couldn't be happier with these JL's hands down best speaker I've owned in a car. Sonic Electronix did a great job getting them to me as well. Look forward doing more business with them soon.

Winter Park, FL.

C5-570x...2 Thumbs Up!

February 23, 2012

I have been a JL Audio fan for many years and have never been disappointed in their products. The C5-5x7s are a great speaker for my rear deck. I own a 2003 Mercury Grand Marquis with a set of ZR component in the front along with a JL Audio 1000/1 for my JL Audio 13w7 and a JL Audio 450/4 for the Mids & Highs. This is a great speaker for rear staging.

Loud n clear!

June 30, 2010

I installed these gems in my /03 Ford F-250 Super Duty Super Cab fronts and powered em' with the JBL GT01004 amp off the SONY MEX BT3700U.
If you REALLY want to give your speakers a run for the money, go ahead and pop in the soundtrack to the motion picture Gladiator! This disc has tracks that will put your speakers through strings, horns, kick drums and some really cool female harmony.
These JL's ate the disc up and spit it out with such musical pleasure I nearly cried.... well... there was a tear but I'm tellin' ya it was allergies :D
