Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Brutus (Hifonics)
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.
1200 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.
600 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".
86 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.
15 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
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.
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.
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.

Ported / Vented
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.
1 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.
1 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.
1.25 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.
1.25 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.

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.

True power

October 4, 2011

I purchased these subs 4 months ago along with the matching 1200rms hifi amp and my expectations have been exceeded. Hifonics have come a long way and the fact there amps are CEA complaint is outstanding. These subs produce outstanding lows and was exacly what i was looking for. About the comment from the guy talking about not having true power, there were obviously other variables and tuning issues causing lack of power.

Excellent bass for reasonable budget

June 10, 2011

I have 2 of these in a sealed box with a 1500 watt RMS Hifi amp and they handle it fine even with the bass turned up. Have not had a single problem with this setup. Anyone who says these are not good subs is terribly mislead. obviously there are bigger and louder subs, but if you are on a budget, I highly recommend these subs, Hifonics is an industry leader in several aspects of good sound, and these prove it day after day of use.

Pretty Good Sub

August 18, 2010

Well, I have 1 of these hooked up to a Sony XM-ZZR3301, which is giving it 600w rms. To be honest, when I first hooked it up, I was a little disappointed because it was not getting as loud as I thought it would, but after a few weeks of breaking it in, it did seem to get a bit louder. So overall, I'm pretty pleased. This sub will hit a wide range of notes, I was surprised at some of the low notes it could hit. And if you turn up the volume, it will get loud. I would recommend this sub to anyone, although I would probably recommend getting 2 if you have the space/money, unfortunately I was on a tight budget.

June 3, 2010

I do not really agree with another comment. This subwoofer works fine. If he is dead is that the settings were not appropriate ... It is six months that I used an amplifier class A / B HFI and it works very well. I recommend it for its value for money.

preety good

September 6, 2012

Right now I have one sub on a weak amp that's only pushing around 300 watts and my cousin can hear me coming from 2 blocks away. So its a really good sub for the price. If u get a good amp and a pro box this sub will hit hard. To be honest if u can afford a square sub u should get it but if not, trust me if u hook this sub up the right way it can out bump alot of subs at the same price. I even wooped two kickers already with this one sub lol so just get the right stuff and go out beatin

Fantastic

March 31, 2012

These subs are worth every dollar and when wired and set up CORRECTLY, peform flawlessly. Very flexible and can hit a wide range of frequencies for different kinds of bass to your taste. As an installer for over 15 years I cannot stress enough how important it is to match your gains on your amps to the rated watts based on your head units pre-out voltage. MOST people fail to do this and then complain they sound like crap or they blew it.

Great sub for a low price

February 17, 2012

So a friend of mine recommended these subs about 5 months ago, I was a little skeptical at first but I am more than satisfied with these. I bought two of them and had them runnind on a lanzar 2000watt 2 channel amp at 2 ohms and they slam. They produce nice clean bass. Great for starting systems.

amp too strong?

May 16, 2011

I bought one of these about two weeks ago and its just as loud as two Audiobahns I had before. But I think I need to get two more because my amp has the voice coils burning after a song. I have a Clarion dpx11500 class d mono block. I think the amp may be too strong?

September 28, 2010

These are my second pair. I have them in my 2003 Chevy silverado extended cab in 2 down-firing subwoofer boxes. They sound decent in there considering small amount of airspace. In my 1995 suburban they were ridiculous with a hiphonics brutus2006 which toasted them but while it was working it pounded too much

Overrated

May 26, 2010

says it handles 600 watts but dont trust it. half power on my Hifonics HFi1000D and it over heated and died. i would recommend you spend a little more money for a better sub if you truly want 600 watts **Note From Sonic: When overpowering woofers keep in mind to tune your system to compensate for the additional power. HFi1000D can push a true 700W+ at 2 Ohms which is a little more power than you want to constantly push into this sub, especially with high gains or bass boost.**
