Hard as Rock Yet Eloquent as Ivory

Speakers are extremely important when it comes to the recreation of high quality sound from CDs, MP3s, radio signals and more. MB Quart engineers built the all new Onyx series speakers from the ground up to be an affordable speaker with the audiophile and performance enthusiast in mind. This series is composed of value-packed 2-way and 3-way speakers that are constructed of the same superior technology in MB Quarts other lines. All Onyx Speakers come elegantly designed with a glossy black piano finish woofer cone and rubber surround. The stamped steel basket touts black high-gloss paint to accent the polypropylene woofer cone and contrasts well with the red progressive cotton spider. Matching these speakers perfectly the line of Onyx Amplifiers shows off the same piano black finish applied to their heatsinks and outer casing. No need to find a match maker, it’s already been made.

You won’t find a lack of features at this price point. Onyx series speakers come equipped with 30mm WideSphere titanium dome tweeter with matching piano gloss finish. The piano black polypropylene cone is suspended by a rubber surround that allows rapid movement to hit all notes. The crossover system has been designed to filter out unwanted frequencies and supply the tweeter and midrange with the power they desire. Tweeter attenuation on the crossover allows 0db, -3db and -6db steps so you can tune your system the way your ears want to hear it. Top it off with a black smoked crossover case to continue with the sophisticated theme and you have yourself Onyx series speakers.

Priced Per Pair

Speaker Specifications

Series
This is the manufacturer product line of speakers.
ONYX (MB Quart)
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.
Pair
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)
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
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.
Inverted Dome
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.

Titanium
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.
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.
120 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.
50 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).
40 - 32,000 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.

No
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.
3-9/64"
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.
2-7/16"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
5" x 7-3/16" 
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.
Yes
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.

MB QUART ONX 157

November 10, 2010

Great speaker for the money. Definitely an entry level Quart but great sound reproduction non-the-less. I wasn't going for professional level audio just something better than stock. I have a ford pickup and WOW did these speakers wake up that factory deck. I'd say not only a clarity/detail improvement but a Volume level improvement aswell. The only thing they lack is bass but really its a 5x7 what do you expect. (Also I'd like to add the placement and size of cab are not lucrative to good bass. Oh and they are a million times better than the factory speakers.)

Solid Speaker for the Money

October 30, 2012

I got these speakers for my "budget" system replacing the stock speaker setup in my '02 Forester. I've been building up my system in stages first replacing the head-end with a Kenwood KDC-X596 (excellent!!!). I've since added the MB Quart ONX216 separates for the front and purchased the ONX157s as fill speakers in the rear doors kick panels. As the stock rear speakers are a bit odd 4-1/2 size, it took some significant cutting and fabrication to fit the space.

The effort was well worth it. As expected, the ONX157 are a far more efficient than the speakers they replaced. The mid-bass response really rounds out the sound, but I have to admit that I'm a bit surprised at the lack of high end reponse from the 30mm tweeters. I'm sure its location so low and forward in the rear doors don't help. Clarity and detail are impressive for a "budget" 2-way. I'm expecting performance to improve once they break in.

I'll be adding an amp (ONX4.60) and an 8" sub to complete the system. I had planned to run the fronts and sub off the amp and continue to run the rears from the receiver (22w), but they may need a bit more power to improve imaging and soundstage.

The ONX157 speakers are a solid value-for-money. The construction and build quality are about as good as it gets. The magnet size is considerable and immediately reassures that you've got a quality product. Highly recommended.

Pretty good little speakers...

August 10, 2015

For $35 bucks, you cant go wrong. Just understand they are not worth the "retail" of $130. No way. But solid great sounding unbeatable speakers for $35 any day.

They look great. Sound very good too.

Tested on 100 watts and installed on 22 watt head unit. Sounded great on both.

The magets are huge for the size also.

Cons:

The basket is very, very thin sheet metal. You can actually bend the speaker frame very easy with just your fingers. Yes seriously.

Manufacture quality- well, they are good for the price, but again understand. One of mine had the surround glued to the cone off center and angled. It looks warped. The other one is better but also has its own defects.

They are a little deep, and the front plastic ring is not removable, so bottom mount might be an issue if you need clearance.

Ohh yeah and no grills. Thats ok though. I didnt expect any.

For me, they are fine. They sound 100 times better than stock. Not as good as my good system, but for a work truck, I couldnt be happier for the cost.

Conclusion. Probobly the best $35 speakers out there. For a little bit more though, you can find a better product but at this price, very good.

Okay for the money, but...

November 23, 2015

The $35 pricetag should have told me, but sometimes you get more than you pay for in car audio. This however is one of the cases where you pay for what you get...maybe a little less $35 gets you $35 (retail) speakers. They sound okay and that's really all I'm asking of them. I'm using 2 channels of a head unit (22W RMS reported) to use these for rear fills while the front satellites are amped. Actually once I got all my gains set up, I can't really hear these. But when I could, when everything was running off the head unit, they provided decent fill.

I was initially attracted by the construction materials & that I had owned Quart stuff in the past. I discovered on delivery however that Quart isn't the same company they used to be. The mounting tab metal is so thin it made me nervous handling them. That same material makes the basket as well - which is sort of curious. This driver flexes with great ease. I realize that once mounted the flex will be minimized, but with the shape of the basket so easily changed, so goes the shape of the cone.

If I had this do again, I'd leave these on the shelf. They sound okay and will work for a pair of shot factory replacements, but I'm having a hard time recommending these to anyone...even considering pricepoint.

MB Quart ONZ157

October 10, 2015

I put 4 of these 5x7's in my 2012 F150 Supercrew pushed by a Pioneer AVH-X6700DVD. Sounds so good! Really loud and super clear. Don't let the price fool you. These speakers sound great! I wouldn't hook them up to an amp because of their low wattage requirement. Sounded good with the factory head unit. Even better with Pioneer DVD player.

Easy and effective upgrade...

October 21, 2015

One of the best bang for buck 5x7/6x8 factory replacements out there.
Good build quality and clean sound make these an easy pick for an OEM swap. Driving these with power from the HU and that's really all I need.
I'm sure an external amp would open these right up.
They could have included speaker wire but no big deal.
This is the 3rd pair I've had and never had an issue...
