Speaker Specifications

This is the manufacturer product line of speakers.
Evolution C2 (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.
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.
2-way Component System
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 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.
Mica-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.
100 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.
60 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".
91 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).
59 - 22,000 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
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.
5-9/16 x 5-9/16 
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.

panama city florida,


May 16, 2011

purchaesed these along with the coax C2 in winter 2010 and rewired my entire car through a audiocontrol LC7 (which i love) and powered them up after two days of work. they fired up with no issues but I noticed something weird after 3 or 4 days of mid level listening... the tweeter would decrease its volume and it would sound like crap. I like to listen to my music fairly loud but the tweets couldn't take the power from my amp. compared to some other speakers the mid bass is lacking as well. needless to say i have disconnect the tweets and the mids sound like crap.... be very cautious or at least dont give'em too much power.

not bad, noticeably better than factory

September 20, 2013

not an audiophile by any means, but i do appreciate a good ratio of sound quality to general loudness...frankly, i wanna blast my music and drive out road noise without having distortion, clipping, harsh tweeters, good mid-bass, etc. these speakers are great. powering them with an Alpine ktp445u (probably wouldnt recommend these comps without an amp)...first time installing comps, wasnt too crazy. the 3/4" tweeters snapped right into the factory tweeter locations with no modification. these do sound much better than my factory "pioneer" comps, but knowing what i know now, i think id go for C3 or C5 comps...dont get me wrong, these are good. the tweeters do clip sometimes at high volumes as others have commented, but that may or may not have more to do with how i tuned (or neglected to properly tune) my system than with the actual speakers. doesnt happen often and is usually remedied by consulting the volume knob...these get loud, play well, complement C2 coax in the rear doors and two 8 inch W3 woofers in the trunk very well. overall im pleased with them, but like i i just want MORE haha. perhaps C3 or C5s in the future. on a downside, these were made in China, as im sure all C2 sets are, which speaks for itself -unless you dont care about that sorta thing. good if your on a budget, better with an amp. i recommend for the price, but if you can, go for a higher end set

Great speaker! Completely happy with my purchase!

February 5, 2012

About 8-9 months ago i decided to put a new HU (Pioneer AVH-3300Bt) into my 2005 tacoma with no expectation of purchasing anything further car audio wise. After I installed the HU my stock speakers improved by quite a bit! Which made me wonder what would a decent pair of aftermarket speakers would sound like?!? Well after hours of scavenging the internet and going to local car audio shops i decided to get these (C2-650) for the front and the C2-650x's for the rear.

Because these speakers are a bit over sized (6 3/4) and have 6X9's up front i had to purchase speaker frames/mounts so they would fit into my doors enclosures. Once I had the mounts and the frames i went ahead and did the install. First thing i notice was the nice crisp highs from the silk tweeters while the speakers external crossover was set to neutral. None of that metallic "tis tis tis" tinging treble. I played around with the -3 +3 settings as well but thought 0 was right on!

I was running the speakers from my HU at what Pioneer said was 22 watts RMS but is probably closer to 12 watts per CEA Compliance. But it did not matter! The speakers sound as good as one could expect from such little power. They produced ample amounts of bass, mids, and highs!!! Now, don't get me wrong. I was not rattling my mirrors uncontrollably or anything but the speaks did a good job from low frequencies to high from HU power.

Well I could have settled with what i had seeing as I am not 18 y/o anymore and am not looking for anything other than nice crisp clean well rounded audio. But now that i had replaced my HU and speakers I couldn't resist purchasing an amplifier (Arc Audio KAR 400.4, 50w RMS X 4, but from what tests have shown Arc under rates their specs and is probably closer to 70w RMS x 4 at 4 ohms).

At the same time i purchased sound dampening material because even with the speakers being power through the HU it was causing things to rattle :-(

Installation of the amp and sound dampening material made a HUGE difference! Man those speaker hummed for the $$$. Now my mirrors were starting to rattle... okay just a little :-) Sounded good at all volumes and when eq properly almost made me think i didn't need a sub.

Yeah, of course... I decided to purchase a sub next ;-) (LJ AUdio 8w3v3-2) and ran the front and rear 6 1/2's in parallel from the amps rear channel's and the sub off the front bridged. I know not the best way to do it but working with what i got. So now with the speakers in parallel and a sub playing with them properly equalized my system is complete!

Long story short every which way I had these speakers set up they sounded great and am 100% happy with. This is not my first stereo and have tried out plenty of other compairable price wise speakers and setups and this is by far my favorite. Of course you could do better if you wanted to spend more but for the price these are above average and perfect for me!

great clean sound

July 25, 2011

Great speakers can hear them very well in my 65 AC Cobra, over the wind and engine noise. I have JL amp (J-320.4) driving them and an iPod.

Oakland City, IN

awesome and precise

January 11, 2010

This component set is everything I expect out of jl audio the sound reproduction is amazing compared to the coaxial I had prior to these. Also sonics price is well worth the money they are as most components not as loud as coaxials but for a person buying components they are looking for clarity which they do and do well. Don't get me wrong they are loud without a doubt just in a different way

Very Good For The Price But Not For High Watt Systems

November 30, 2012

Overall I am very happy with these. I had a set of JL XR's in my old car which I loved and that is why I bought these. Very clear and GREAT bass response. Had to cut mid bass driver surrounds to install in a 2006 Grand Prix GXP, a spacer may have also worked, but depth wise they fit no problem.

Now What I Don't Like:
JL has put tweeter protectors in their Cross-Overs. This results in the tweeter dropping out from time to time. VERY annoying and makes one think there are other issues. If you are driving these with more the 75 Watts RMS you will probably experience this (I am at 110 watts RMS). It is possible to remove the protection device however they add a little resistance to the tweeter's cross-over so the highs might be a bit brighter than before. Another option is to run the tweeters at -3db or even do both. I am considering upgrading to the ZR tweeters to solve my issue as the tweeter sounds stressed when pushed. At mid volume they are VERY smooth and detailed.
