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.
1800 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.
900 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.
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 - 2200 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".
96 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
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.
Reinforced Paper
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.
Not Specified
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.
6-11/16"
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.

Amazing sub!

March 11, 2010

This sub is cheap and hits hard, I bought this with a 1100 BOSS amp and I bought a ported box, this thing shakes my trunk like crazy and everything in my car and I usually only have the volume on my stereo at 20. It's a little bigger than 12in so cutting has to be done to the box to make it fit. But trust me, this thing is worth it and it's cheap, I plan on getting a second one

good for the money

February 20, 2010

Bought these subs over the summer and installed them each in a small sealed enclosure (1.25 cubic feet). Definitely not the right size for these speakers because the bass starts to distort when I turn up the gain. I bet these subs will shine once I put them in an enclosure built to their specs.

Boss LAC129D in my Ford Focus 2.0 euro version

December 29, 2009

Budgetary subwoofer. What is the average between the device for competitions on SPL and a qualitative sound. I have established it in a box with subwoofer in volume the recommended manufacturer. The box is collected from plywood of 18 millimetres of a thickness. Strengthened by partitions and glued on all joints. Frequency of a resonance has turned out about 35 hertz. The subwoofer works from the amplifier of monoblock Polk Audio 1200. Such decision has allowed to receive a loudness maximum level in 127 decibels. The windshield of my Focus at such loudness decently enough vibrates. As I apply this device not to competitions and for listening of music that I cut off the top border of a signal reproduced by it approximately on 70 hertz. As the head device (Kenwood XXV-01 - it is euro version) is equipped by the sound processor pleasant enough, musical sounding has turned out. Localisations of an arrangement of a subwoofer are not present.
In general this device completely justifies the put up money. Excuse me for my bad English. To difficultly enough inhabitant of Russia to describe a technical material on not a native language.

speakers go BOOOM

February 9, 2009

i have two of these in a built to specs sealed enclosure and for a not so famous brand, these guys hit. i have each one powered separate by SSL 750 w monoblock @2ohms Approx 600 to 700 watts each and they rock. if i had a more brand name amp the guys would shine but awesome speakers anyhow for the price.

Love it.

December 25, 2009

I got it for a early Christmas and I love it, it shakes everything and my amp is only at 900 watts right now. I'm going to soon put it at 1800 watts and get a second one, I love it. I recommend getting it. It's cheap and good quality. the only downside was I had to cut alittle more out of the box because it wouldn't fit into the 12in box.
