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.
1000 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.
500 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".
90 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.

Main Cone Color
This is the color of the speaker's or subwoofer's cone.
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.
Aluminum
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.
Butyl Rubber
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.
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.

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.

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.
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.
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.
Minimum Ported Box Volume
This value indicates the minimum ported 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.
Maximum Ported Box Volume
This value indicates the maximum 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.
6-3/10"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
11-1/10"
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.

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.

volfenhag

March 8, 2012

I have the 12inch volfenhag 1200watt hooked up to a 1000watt amp and its hooked at 2 ohms and it hasnt blown yet or even showed a sign of it. I also recently purchased the 10" version and have that also hooked up to the same amp on the second channel at 2 ohms. These subs are better than alot of subs out there. I know for sure they are way better than a kicker cvr 10 or 12. I can prove it. The magnet size is way bigger than alot of 10s or 12s. Come listen to my system and everyone will think twice about any other subs around the price of a volfenhag.

volfenhag 10" and 12"

October 13, 2010

READ THIS!! ... this is a real review from a real person that has owned a couple pairs of these subs before. These subs are good budget subs and they can hit pretty well but they are not 1000 watt subs, if you hook 1000 watts to them they will blow and will blow fast, you will burnt the voice coil putting too much watts to them and you will smell them right before they start to give out. If you start to smell them burn turn them off for awhile and you can play them again in another hour. I don't know the real wattage for them they can handle but test what they can handle slowly and don't put too much to them at once.

Great Sub

January 6, 2009

I was lookin into buying subs for my civic after i blew out a friends alpines with my 2000se boss amp. I have em wired at 2 in a series(yes i did my own installation, its better to know what is going on with equipment such as amps and subs) and after i let a tone cd break them in and played with my volume low, the subs were ready for some serious pounding. Great buy for the price. I would recommend these. Great buy

April 10, 2008

I just wanna say this thing pound wicked even at low volume. I just got two of these a week ago. They are hooked up in parallel/series to a 2400watt pyramid pb-1836gx in a sealed box and i was pleasantly surprised at the resulting boom i know they are not the best out there but you can not beat the db's that come out of these beautiful looking subs if hooked up correctly. I will be reporting back on their progress as i continue to enjoy the rumble in my stomach from 2000 watts of a german concept.

December 10, 2007

I've had two of these subs for about 8 months running off only a 500.1 Phoenix Gold Class D amp, and they hit extremely hard in my Ford Ranger. These are very good, I recommend this sub because it has won three local bass competitions and can be heard 2.6 miles away! And the other reviews about the voice coil messing up and stuff, it never happend to me.

Great Sub!!!

October 18, 2007

I have 2 of these subs running off a 2400 watts max Volfenhag Amp (400 x 2ch @ 4ohms) in a sealed box and they hit real hard. I bought them around a year ago and they are still thumping! I have it in a Mazda 626 and the trunk rattles like hell when i have the volume at 20. One time i was looking for a spot to park at my college campus and i triggered around 3 or 4 car alarms when my volume was at 30 and playing a rap song (the funny thing is that the cars were not close to me, they were pretty far away) . Overall, these subs are great for the price. I would recommend these subs for anyone who doesn't want to spend a lots of money for hard hitting subs.

Great sound, Poor quality

July 24, 2007

I had this subwoofer for 2 weeks, running an actual 500 watts RMS to the sub, and as you can tell it lasted 2 weeks. The sound was incredible, very deep bass, a little distorted, but over all sounded great.. where they get you is the quality.. it is a good buy for 55 bucks, just determine how much you are able to spend then get the best you can afford... i have learned this the hard way many of times.

These Sub's are awesome! I have two of these hooked up to a Volfenhag 2000 watt Amp in a bandpass enclosure and they are great. The bass it nice and tight and they hit so hard. Don't believe what all the stereo shops tell you about this company making crappy products... they look good and sound excellent. You can't get a better sub for the money.

So-So

January 26, 2006

Although I don’t own them, my friend does. He has two of these. They get loud as anything! If the volume is at half it is uncomfortable to breathe…. If your looking for an obnoxiously loud system which you wont be able to decipher any of the words this is the system for you. The sound quality is terrible on these. If your looking for a system which will sound good… do yourself a favor and don’t go with these spend the extra $20 and get something better.

I have owned these subs for a year now, and they are still thumping. I first started out with 2 subs, that I decided to get 2 more. It is a great value. Especially having 4,000 watts of power in the trunk. Just make sure you know how to hook up a dual voice coil before installing them in a box.

This subwoofer is ok...

November 27, 2005

I have owned this subwoofer for approximately one month and am not satisfied. It pounded tremendously hard for a while, until the voice coil blew. Save up for a better sub such as a pioneer 306c (editor note: Kicker 05S12L54 would be a better choice. The Pioneer TS-W306C is an entry-level subwoofer).
