Note: JL Audio describes this model as a 6" speaker size; however, most manufacturers designate this same frame size as a 6-1/2" speaker. To clarify and simplify comparison's to other products, we list it in both the 6" and 6-1/2" categories of speakers, and refer to it as a 6-1/2". It is a perfect fit for many Japanese vehicles that will only accept a true 6" speaker without modification and not a standard 6-1/2" or 6-3/4" speaker. The basket features three and four-hole patterns that match up with all factory mounting locations.

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.
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 Injected Polypropylene (MIPP)
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".
90 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 - 22000 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.

Good Speakers

June 20, 2012

These are decent sounding speakers. The highs are clean. The mids are pretty good too. The mid-bass is ok. The bass response, is expected, isn't there (if you want good bass, buy expensive, high quality speakers... if you want good and deep bass, buy a sub). Overall: I recommend these speakers. They are good enough sound quality for the price range.

Decent sound from a small speaker

November 13, 2011

Direct fit in the factory door opening of a 1979 Ford F-150, no mods required. Sound quality is good even though it is powered by an OEM AM/FM radio that is 30+ years old.

Denver, CO

Outstanding upgrade. Great experience.

April 30, 2013

I purchased these speakers for the front doors in my 1994 Bronco. I wanted a really great set of speakers that were a solid upgrade over the JBL's that the previous owner installed which had begun to malfunction. I wanted something with nice bright highs and full mids that would take plenty of power. At this price, these went above and beyond my expectations. The coax is also super easy to install. Overall an outstanding easy upgrade to my Bronco. Sonic Electronix was extremely helpful, had the best price, and took excellent care packing and shipping my order.

Great speakers for low price!

February 23, 2010

These speakers deliver clear audio. The base tones are clearly distinguishable from the high and medium ones. The power they pump is more than adequate to fill a medium vehicle. I have mounted on a Honda CR-V 08 and the difference from the stock speakers is remarkable. I'd recommend these speakers over some other brand not only because of their sound but their quality--i.e., I've never seen any other speakers with their magnets insulated with a high quality rubber. Just because this fact alone make the JL Audio speakers a winner in my book!

What would you set the HP filter at on the HU for these?
A shopper on Dec 27, 2014
Best Answer: Hello,

That is completely determined by Preference and the Overall Setup. If you do NOT have a subwoofer, then you may not want to set the HPF at all, or you will loose ALL low end in the vehicle. However, if you intend to simply 'protect' the speaker from low end frequencies that it is not meant to play, then you look at the Frequency Response of the speaker (59 Hz - 22 KHz) and that essentially tells you where to set the HPF, ~60hz .
If you DO have a subwoofer, however, then have the Speakers 'pick up' where the subwoofer leaves off. For example, if the subwoofer's LPF is set to ~120hz , then have the speaker pick up at ~100-120hz, for a proper full range setup.
