Speaker Specifications

Series
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.
4"
Design
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.
Dome
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
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.
Aluminum-Coated 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.
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.
150 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
Sensitivity
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).
74 - 20000 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.
1-7/8"
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.
3-3/4" x 3-3/4" 
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.
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.

Amazing Improvement

October 6, 2011

I bought two pairs of these to replace the standard door speakers in a 2009 BMW X3 E83 LCI. This car had the basic stereo. The improvement after fitting these speakers in the 4 doors as been simply amazing! Loving them. In terms of the installation I just want to say that although I was able to fit them, there are a couple of issues. 1) I had to file down the plastic edge of the Tweeter so that they would fit. This wasn't a big problem but it just required a bit of time and patience. 2) The woofers (Mid) are probably 1-2 mm thicker than the space available, but I was able to fit the door panels back in without needing to modify anything. All in all a very good option if you want to upgrade your X3 door speakers.

Great Sound... Great Price

June 4, 2010

I just got finished installing an all around MTX system in my 01 A4 using these for the front doors. To say the least I'm impressed with what they can take and the sound they deliver. An excellent product for the price. I was also happy with the "make an offer" option which allowed me to purchase these for somewhere around $90.00. Thanks Sonic. I'll definitely be back.

Great speakers for the price!

Ear bleeding sound! These go so loud my 6.5" Rockford Fosgates in the rear can't keep up and make a crackling noise so had to turn down the gain on the rockfords. Amazing for their size don't produce much bass but I run them with a 15" so only need the sound not bass so they're very good as they're designed for sound not bass. Better than my old yellow Pioneer kevlar 6.5" Splits

OMG Speakers!

May 4, 2011

Well, if you're someone unfortunate enough to get stuck with a 4inch speaker hole, this is a great way to get some solid mids and lows. I put these in a Mazda B2600i with the tweeters mounted on the dash, and some Memphis msync 8s in the back, and it was way more than I needed. The crossovers aren't as bulky as most, though I could do without the stylized covers on them. Speakers come with everything you need to mount the tweeters, with several different tweeter pods for the angle you need. If I didn't already like MTX I certainly do now!

Excellent Product

April 27, 2011

I highly recommend this set to anyone who needs a great high end component set at a reasonable price. I bought these as a replacement for the factory Boston Acoustic speakers in the dash of my magnum. Absolutely blew the factory stuff away! Sounds great even without being amped. When I received the set one of the woofers was defective but just as promised it was covered under warranty. Awesome product and great website. Would highly recommend both to anyone.

not to bad

December 31, 2010

after the first set did not work. 3/47 speakers defective i was pretty discouraged. The mtx warranty department in wisconsin was A+ in serivce and they sent me 2 new pairs no questions asked. These worked perfeclty fine and powered to 75 watts rms each they sounds pretty crisp. not the cleanest sound in the world and not much midbass, but theres only so much a 4 inch speaker can do.

new respect for MTX

May 15, 2011

I own a Saab, and I do my own installation on my cars. European cars are a real pain to work with so you only want to do the job one time. I have these hooked up to a Kenwood class D amp with a Infinity 10 sub. I have to admit I was afraid these speakers would not hold up, but after 6 months. The highs are great, the mids come through well, and with the crossover the lows don't get through to distort. I listen to everything from rap to country to instrumentals. Can't totally remember but think I paid about 90 with best offer. This was worth every penny.

Great Dash Speakers

August 15, 2009

I would highly recommend this product, i have these in my reg cab Toyota pickup, replacing the 3.5 inch dash speakers. The mid woofers are great, as are the tweeters. to mount the tweeters, they give you surface mount brackets, and recessed mount ones. the crossover has a -3 db option if u want to tone it down a bit.. high quality parts, sounds clear, and can take a lot of punishment. great for something to get rid of those crappy stock speakers.. 5*
