Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
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.
500 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.
250 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
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
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".
88 dB
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
White
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.
Foam
Magnet Structure
Defines the overall structure of the subwoofers magnet.
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

Optimum Sealed Box Volume
This value indicates the ideal sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
Optimum Ported Box Volume
This value indicates the ideal ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
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.
5.4"
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

Electromechanical Parameters

Free-Air Resonance (Fs)
The free-air resonance frequency of the subwoofer, measured in Hz. At this frequency the weight of the moving parts is perfectly balanced with the subwoofers suspension system.
Equivalent Compliance (Vas)
This is the amount of air that has the same stiffness as the subwoofers suspension. The greater the rating, the lower the stiffness and larger recommended enclosure. It is measured in Liters.
Total Speaker Q Value (Qts)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including all dimensionless losses. Essentially, a high Qts value (closer to 1.0) means the subwoofer is great for sealed enclosures and a low Qts value (closer to 0) means the woofer is great in vented enclosures. A Qts of around 0.45 means the woofer will work decently in either enclosure type.
Electrical Q Value (Qes)
The subwoofers relative damping (Q) at the resonance frequency (Fs), including electrical losses. Also called the mechanical damping of the subwoofer. The unitless measurement usually varies from 0.5 10.
Electrical Resistance of Voice Coil (Re)
Amount of DC resistance of the subwoofer when measured with an ohm meter. Typically, this will read less than the impedance rating of the subwoofer.
Mechanical Q Value (Qms)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including mechanical losses. Also called the mechanical damping of the subwoofer. This unitless measurement usually varies from 0.5 10.
Efficiency Bandwidth Product (EBP)
This number represents the trade off between having an efficient woofer and one with a wide bandwidth. To calculate this number, take the Fs and divide it by the Qes. If the number is below 50, the woofer is designed for a sealed enclosure only. If it's between 50-100 it can be used in either. Lastly, if it's greater than 100 it's designed for vented enclosures.

lots of bass

April 19, 2010

I have two of these in a super bass pro box and they are amazing. I have them running on a Crunch GroundPounder 2500d @ 2 ohms and they beat harder than the four 12's I had before. Great buy!!!!!!!!!!!!!!

January 10, 2010

I love these subs they are great. I recommend them because they have good quality sound and move a lot of air which makes a lot of bass. You do want to have them firing to the back of the car or down to the floor. The cons are they cant take allot of power (250w RMS) but still will rattle your eye balls out. I love these subs because for only $100 you get a great quality product.

i have one of these in a ported enclosure 2.0@33hz and it blows way powerbass, pioneer, soundstream. keep in mind all these woofer were entry-level. ive also owned 2pr 15s sealed @4.2 and they were loud as well AND VERY CHEAP AND DURABLE. SUB IS ALSO EASY TO INSTALL THANKS TO THE PRE-DRILLED GASKET

Great for the Money

July 20, 2009

These were the first subs i've ever had. I am extremely pleased with my choice of memphis subs, and would recommend them to anyone who wants a well-rounded system. I have it hooked up through a 1000 watt amp. I've got 2 of them, in a ported box in the trunk of my lumina ltz.

The best

January 18, 2009

I have 2 of these in a ported box with a 2ch memphis 500 watt amp and I have the gain half way up and my bass all the way down because it drowns out my highs and mids. These things are amazing. They hit harder than my friends alpines and they hit very deep. These things have destroyed my rear view mirror and my trunk. The bass is mind blowing. I was looking for a sub that was more focused towards sound quality instead of spl and these did the trick. I don't care about being heard blocks away but if i want to I just crank this to like 30 and they bump HARD!!!!!!!!!! Best sub for the best price!!!

January 2, 2009

I had 2 of these in a 3.5 cu. ft. ported box running on a Memphis PR 500.1 in my Ford Ranger and EVERYONE heard me. my friends said they beat like 15s and tons of people wanted to buy it. then my dad said i had to get rid of it. i kept the amp and went to a smaller box and kicker cvr. I don't like it, its not very good at all, and i missed the PR's so bad i just went and bought 2 more and built the same box i had. I'm waiting to get it in now but i already know I'm gonna be heard Blocks away. I RECOMMEND THIS SUB TO ANYONE!! WITH THE RIGHT AMP AND BOX THIS THING WILL BEAT LONGER AND HARDER THAN ANYTHING COMPARABLE. ITS GREAT!!!

February 21, 2008

I have owned a single 12" Memphis Power Reference DVC for a while now. with my very limited space I started out with a cheap .7cube truck box and was not that impressed with this sub. I recently stepped up to a 1.9cube slot ported truck box that Memphis released for 2008 and OH MY LAWD this thing hits!the box goes nearly all the way across the back of the cab in my 78 Chevy C10. I am powering the sub with a JL Audio 250/1 amp and have never had a problem! in a ported box I am amazed by the sound this little bugger can put out! value wise this is unbeatable. if you want a low dollar system that HITS this is it!

memphis power referance

December 6, 2007

i have 2 12's in a dual ported box in my dakota extended cab... running on a jl 500/1 amp.. these things are no joke .. they pound.. great sub for the price .. only thing is mine now pop when turned up past 22. the wear out easy with an amp like that since it pushes more than they need . but if you get a 400 watt amp and a box like mine .. you will feel it..
