Setting the Bar for Reference Sound

The MB Quart QS216 car speakers are brand new for the 2011 MB Quart Q-Series. With the high expectations that come with the Q Series, there is no doubt that these speakers are among the finest ever created. Holding true to the legendary Q Series sound, the QS216 speakers bring reference audio to a new level.

High Definition "Q Control" Crossover

Much of the sound quality of a component speaker system rests solely on the quality of the crossover. The MB Quart QS216 include a high end crossover that true audiophiles will appreciate. The solid construction and top-notch craftsmanship easily set it apart from the rest. Advanced "Q Control" inside the crossover allows for avariable points of attenuation in the midrange and the tweeter. MB Quart also included their Balanced Temperature Control Technology that will ensure the integrity of your music will never degrade or suffer over extended periods of high power listening. Go a step further by adding the ability to bi-amplify the tweeter separately from the midrange and you are set with the ultimate crossover.

A True Audiophile Midrange

One glance at the midrange woofers and you think there is something special about them. Once you pick them up, you know there is something very special about them. MB Quart uses a Nomex PMI Composite sandwich material in the speaker cone. The material is lightweight and rigid, two of the most important attributes when constructing a speaker cones. The combination results in a flat linear response with brilliant low frequency response and high sensitivity.

Breathtaking Tweeter Design

The tweeters included with the Q-Series QS216 are a large 40mm in diameter and made from a Teteron silk composite. The result is beautiful acoustic reproduction that rivals the highest end of tweeters. Flawless reproduction of audio frequencies and improved durability are a direct result of using the advanced materials. Flush and angle mount hardware is included and helps to mount the tweeters in a variety of locations.

Speaker Specifications

This is the manufacturer product line of speakers.
Q-Series (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.
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.

Teteron Silk
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.
Nomex PMI Composite
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.
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.
170 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.
80 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".
89 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).
35 - 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.

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 or millimeters, required to contain the speaker.
5-5/8" x 5-5/8" 
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.

In 20 years in car audio...these are the BEST, cleanest, and most PRECISE components I've ever heard (I'm using the MB Quart Q4150 to run the tweets and the mids active, and it is phenomenal!!!!!!!!!!!!! I've only had for one day, but been in the car for 12 hours, and these are NICE!!!!!!!!!!!!!!!!!!!!! I'm gonna save more money to buy a back up set in the future (be prepared, the tweets are HUGE, but not harsh, even active-great job Maxxsonics, and Sonic:-)ps, shipping FAST AS USUAL

Precise, outgoing, so powerful, bold and full of range. I am running a RA640.0 into them in the front. Absolutely happy with my order/choice. Not only did I get the high end speakers I was looking for, I bought them at the lowest price I could find them anywhere (web or retail).

While I don't consider myself the greatest reviewer, I'll do my best to share my feelings here.

From the beefy rubber surrounds, monster-sized magnets, the solid feeling tweeters, all the way to the hardware was top notch! The crossovers were the most impressive part. Nice quality gold connectors, the ability to run them active or passive is a nice feature too. Just be sure to really take a look around your car and make sure you have the space for them! They are practically the size of a VHS tape and weigh a lot. Overall the build quality is amazing. They are exactly like their German predecessor from back in the day (as they should be for the price they are).

Okay on to the sound. I've owned Polk DB, Polk DXI, Infinity Reference, JBL GTO series, and now this MB Quart QS216 model. They are all around a better speaker. The midrange is tight, precise, smooth. If you ever listened to something like Best of Santana, all the various percussion instruments really come through and don't at all sound like a cluster of unorganized noise. Bass guitars sound like bass guitars. I apologize for being so vague, It's one of those things you have to hear to believe. I guess the best way I can describe the midrange is they sound like 10 different speakers; 1 for each instrument so there is no interference between reproduction of sounds. The tweeters are my favorite part. Teteron silk so they are nice and smooth. Cymbals sound so incredibly real it will blow your mind. They snap and are bright, but not overkill either. I didn't think it was possible to have a clear snappy tweeter being played at high volumes and be left with your ears feeling fine, no ringing :-). All the other reviews said it right! Everybody here "5-staring" these speakers all across the board is no mistake.

All I have to say is that this speakers sound awesome... and for those people who doubt this component set... I have to tell you that the Crossovers used in this system are engineered the same way as the German Maestro MS 6508 which is the company that used to be the original MB Quart in Germany... the QS216 speakers and tweeters are different from the German Maestro MS6508 but they are still built with great quality, and the sound is crystal clear... In other words they do Sound Amazingggg!!!

Beyond Amazing!

June 4, 2012

These speakers, being the MB Quart Premier Component Speakers, is the exact thing your car will need to take it to the next level. I would compare the quality of these speakers similar to listening to a typical 10 year old child learn how to play an instrument and then moving on to listening to the Boston Pops perform. The clarity of sound from the tweeters to the extreme coverage of lower tones and bass notes from the woofers give you the best experience that a car speaker could have.

My only qualm with the speakers is that the woofer is large (make sure you can install it), the tweeter is quite large (the magnet behind the actual tweeter), and the crossovers are huge (make sure you have space where you want to install it). I drive a Toyota Yaris and I made them fit, so my size complaint is extremely minor. :)

good deal

October 12, 2014

I purchased the components mb quart Q series for my 99 tahoe, and after shopping around i must say the sound quality is better than most..... Of course you guys know mb quart is produced in China, it still has that sound you look for in a quality system. I believe these components fair up to any of its competitors... They are a good deal at that price.... Yes their are alot other to choose from, but at this price the sound quality you get is outstanding.....I tried jl audio C3, polk audio, fosgate t3... These components are over $400 bucks and for half of that you get a better sound

Sounds great, perfect fit.

March 10, 2012

I hoped for super sound for my '95 Supra and these MB Quart QS216's even exceeded my expectations. I have two sets installed in the stock speaker locations, so two in the upper front of each door and two in the rear under the rear quarter window. I'm driving them with a Pioneer AVH-P3300BT, which exactly fit the OEM double DIN cutout, and the Pioneer head unit feeds the MB Quart Q4.150 amp which drives the speakers. The sound is very good. They project clear voice and midrange and the higher frequencies do not sound hard or unnatural at all. Bass is very good and tight being I have the four 6-1/2", but I'll be adding a subwoofer anyway to get that extra bump for some types of music that benefit from that.

Stop reading and just buy them

April 8, 2015

This was my first set of components and I was a bit iffy about the price but I decided to go ahead because I wanted good quality stuff plus everyone said the tweeters weren't bright which I HATE. This component set sounds like I have a sub installed when I don't. I have them in the from and back doors of my 2015 Elantra powered by a hifonics brx640.4 . I would have it no other way!

Amazing product!! Best I have ever heard.

I read very positive reviews, great feed back on the ones who have already tried the speakers out.
ranjit m on Dec 1, 2014
so do these run at 2 ohm or 4 ohm, and if at 4ohm how would I make them run at 2ohm?
jeff b on Nov 12, 2014
Best Answer: Hello Jeff,

They are 4ohm Speakers, and will only read 2ohm if paired to a sharing Channel. This will likely do nothing beneficial - apart from freeing up a channel - because you are still going to share the power at 2ohms, making this moot. 70w RMS @ 4ohms to the speakers is still a solid figure; Especially if your amp's manufacture is known to underpower. In regards to the Extra Tweeters, please do your homework on hooking up multiple speakers. Doing this alters the impedance if you are planning on going to the same amp. If the impedance doesn't match across the amp, it will stress it, and eventually fail.
