Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Reference Low Profile (MB Quart)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
10"
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.
600 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.
300 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Dual
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
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).
25 - 160 Hz
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".
82 dB
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
8.65 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Black
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.
Injection Molded Polypropylene (IMPP)
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.
Foam
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
No
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Sealed
Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
.4 cubic feet
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
.65 cubic feet
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.

Good little sub!

April 29, 2014

I was looking for a shallow sub for the side of my Vw polo IV trunk. I wanted some extra bass for my system but not like the bigger subs I had. When I played a couple of ours i raised the volume and was surprised how powerful it was for such a shallow sub! So if you want a shallow sub that gives good bass this is the one to buy!

Great sub

August 22, 2010

I bought two of these for my Chevy Avalanche. I needed a sub that I can install without altering my truck. These are in individual 0.55 cubic feet boxes under the rear seats and I have a MB Quart RAB 1450 amp pushing them wired to 1ohm (about 450 watts RMS) and they sound great. I kept my factory Bose system and just added this setup and I'm very satisfied. There's plenty of bass inside and outside my truck. Definitely recommend for anyone especially if you have limited space.

Good for small systems with no bass.

May 15, 2013

I put 1 of these under the rear seat of my Quad cab sierra denali. There was plenty of space for it plus an amp. But didnt produce enough for my liking. For the price and mounting depth it is pretty good. If you want to feel the bass you will want multiple (4+) There is just not enough excursion to get much SPL or db out of one or two. But they were pretty clean. So if a little fullness is all you need than these will work and u can save a Little $ too.

Just like its cousin...that's a good thing.

June 23, 2014

This sub is the same as the Hifonics Gladiator GLX10D4 (which was $30 cheaper), just with MB Quart graphics on it. I have one in a sealed .8 cu. ft downward firing box (no polyfill) with 320W RMS. The sub plays low and is tight -sounding already, so no need for me to go with a smaller box and polyfill to compensate. I got it because it can be 2 ohm configured to match my amp's RMS output perfectly. It's a great-sounding sub and fits my application well. I haven't tried to put it in a ported box since the manual does not say it's OK to do so, but I think this sub would be much louder and still retain its tight sound in a 1.0 cu. ft ported box. That would defeat the purpose of having a sub capable of shallow mounting though...so small sealed it is. With some break-in time, I hope it does get a bit louder than it is now, but I am satisfied with the low end range in my small sedan. Sensitivity is a bit low at 82 dB, other shallows I own go as high as 90 dB so you can hear them better at lower volumes. If you need a shallow sub, this one will fit the bill - but you may want a little more oomph if it's in your trunk and not in the cabin with you.

Great Subwoofer, great price

December 13, 2013

Researched a little on subs. Found this sub for best fit on budget and specs. Built homemade sealed box aprox. .25cuft as manual says for each. Placed behind f250 crew cab seat. Powered by a mono block 1200w amp. Did previously buy first sub from diff. Store at higher price. These 10s perform great. Very clean bass. Highly recommended.

Beyond Expectations!! Awsome Sub!!

October 11, 2012

I was searching for a slim sub for my 1998 Chevy Suburban. I found this MB Quart RLP254 and liked the specs I read. I had to design and build my own custom enclosure just because I wanted it to be under the middle seat on driver side. There are plenty of available enclosures out there that this sub would work perfectly in, just not for my exact design. I was able to get the enclosure to .77cu.ft. and packed full of heavy poly-fil just like the specs suggests. best part is the box is completely out of the way and "invisible"!! After all said and done..... WOW!! This sub hits hard and is extremely accurate and tight! Just one 10" sub fills my full size Suburban with clean, accurate, tight bass like some other 2-3 sub systems I've owned in the past, of course it doesn't pound the side walks loose like those systems but if I were to run 2-3 of these MB Quarts I bet they would with ease! If your looking for a high performance slim designed subwoofer... look no further!!

Better than expected

May 9, 2012

I bought 2 of these for the storage compartment in a 2007 Trailblazer. Well we bought a minivan and guess what I get to drive. Anyways very impressed with these little subs so far. I have them in a 1.3 cubic ft box with medium fill and an 1100 watt Diamond Audio amp wired at 1 ohm. Not broke in yet and they fill the van nicely and don't take up the whole back. Definately recommend
