Priced Per Pair

Speaker Specifications

This is the manufacturer product line of speakers.
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"
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.
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.
240 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.
120 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".
92 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).
55 - 20,000 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.
3 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.
Bottom-Mount Depth
The depth when installed from the bottom of the mounting surface. Measured from the bottom of the speaker's magnet to the top of the mounting holes on the rim of the speaker.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches, required to contain the speaker.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
3-5/8 x 2-1/2 
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.

Good value for the price

February 14, 2013

I use 4 of these speakers with a boston acoustics amp @ 100w each RMS. When first installed they were actually louder than I could stand. After 6 months of prolonged use (I spend a few hours a day in the car), they aren't as painfully loud as they initially were, but still very loud and clear. For the price, they're hard to beat.

Good buy Quite

September 23, 2012

I have had these for close to a month now and they are not the best but they are good for the price. For some reason they are not very loud and never get very loud. It almost sounds like my back speakers have to do most of the work. They just don't put out a lot of sound but the sound they do put out is clear.

They were alright

September 7, 2012

I have heard and owned many different door speakers these spins pretty good but I don't like the crossover to much slack and I didn't want to cut it they sound great with miss the highs can get raspy and ear bleeding and without a deck or amp to control the frequency it will play super low which sounds like crap I also had to trim the side to fit

Queens NY

wow great speaker!

June 17, 2012

I have both the Infinity Reference 6832cf, and the better Infinity Kappa 682.9cf.
I bought these after the 6832 tweeters died on me. These have that external crossover just like my better Infinitys 682.9cf, so I bought them to replace the lesser 6832. These speakers amazingly sound similar to my better Infinitys but have a smoother upper miss and treble.
In fact I like the whole mid range and smoother highs better than my infinitys, except the bass is a little lacking. While it has better sound and bass than the ones it replaced, It didn't have the effortless extension in bass of the best infinity, but that's fine as it was new and not broken in and costs half the price as the infinitys.

Personally I prefer the smoother more liquid highs of theses compared to the more etched and sizzly highs of the infinity. The upper midrage on this unit also seem to have more presence as well, compared to my infinitys. I would put these right up there with the best speakers, as they have a realistic sound to them, which only my better infinitys had.

Great speakers

August 1, 2012

These are very clear sounding speakers, the highs and mids are very clear, and for the price, they cant be beat. They really come to life when using an amplifier to them vs using the deck. Since they were out of stock.I had to pay more from diffrent website, really good speakers

A "Must Buy"

July 14, 2012

I must buy another set when it becomes available.

These are now just as loud, clearer, and more natural sounding than my best Infinitys! They can take the power of my amp. I had these with my top-of-line Infinity Kappas woven glass speakers and I just cannot believe this.

The top-of-line Infinity tweeter burned while the other Infinitys (plastic cone version) in the back totally burned out and died!!
My amp was too much, but also I think the fact that those were 2 ohms made it worse as the amp pushed too much current in them.

This unit, by being 3 ohms, is best as it is now "broken in," and is now just as loud as the top-of-line Infinitys were. Also TOOK ALL THE POWER I GAVE IT WITHOUT DISTORTION.

I had the amp on "high pass" only, so no bass. These were only pushing mids and highs. THEY ARE MY BEST SOUNDING SPEAKERS TO DATE AND I HAD ALL INFINITY BEFORE!!! For mids and highs they are excellent!!

A MUST BUY!!! for the price! :)
