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.
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
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.
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.
Nitrile Butadiene Rubber (NBR)
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

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.
1.00 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.
2.00 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.
1.75 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.
6.7"
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"
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.

these subs!

March 20, 2012

Don't under estimate these subs. They will blow your ears off. I promise. If you have the right amp. I have an 1800 watt Kenwood and my rearview mirror feel off. My neighbors didn't like me very much. But I would highly recommend these subs to anybody. Even if you have P3 l7"s or solo XS.

BRUTUS ALL DAY AND NIGHT !!

January 29, 2012

Do not hesitate. These subs will rock you! If you want the big boom! Put these babies in a shared 3.4 cubic box with a single slot port tuned at 38 hz in the center of them. I have them running about 1 ohm (box rise 1.1 - 1.2) powered by a second generation ORION 250 HCCA DIGITAL REFERENCE. I will quote my sons reaction when coming 3 blocks away "Dad, it sounds like an earthquake approaching" Now hows that for a review.

big sound in a small package

November 20, 2011

I got a pair of these in a trade about a week ago and im very happy with them. I have them in a vented box and hooked to a sony explode 1000 and these things hit hard and not even getting enough power to push them hard. I have them in a jeep cherokee and have gotten 3 noise complaints. I cant wait until i get a bigger amp on them and see their full power.

Great subwoofer!

August 29, 2011

I bought one about a year ago, have it in a sealed box, and it sounds GREAT. Gets VERY low, and gets pretty loud as well, I haven't gotten a chance quite yet to hook it up to an amp that will really show it's potential, however, with the amps I have hooked it up to, It's GREAT. I'd recommend to anybody that wants a cheap way to get some decently loud bass in their ride! So far, really haven't found any cons! Love it!

Good subs

August 17, 2010

Ordered 2 of these subs on August 13th, on a Friday. Got them the next Tuesday the 17th. Hooked them up in my Jeep Cherokee in a ported box and a 300watt Rockford floodgate punch amp and WOW!!!! hits really hard even on only 300w atts. Good sub for the money and great for beginners.

July 17, 2010

I am 14 and have this sub in my room, I only have 150 watts going to it but it still rattles my door and has made things fall off the walls. You can also see my window in my room flexing from out side. It also sounds great and hits the highs and the lows. If you are looking for a cheap subwoofer for you car or room this sub will be great for you. The only thing that worries me is the magnet cover, it seems really cheap and it seems like it is loose.

Wow in a good way

June 3, 2010

I've always been a kicker fan. I downgraded from a 15 in L7 because I wanted trunk space. So I bought this Brutus 12 inch sub and for $70 it's worth every penny. It sounds great and puts out a lot of bass. It has a good design and looks and feels durable. It's powered by my Rockford amp which is also a plus. Overall I give it 5 stars.

They Slam

April 27, 2010

when these came out my friends n i gathered money and i bought 6 12s, 4 10s, 4 15s, for the price, they couldnt be passed up. all my friends are running a pair of these subs with either the brz1200.1 or brz2400.1 brutus amps and they slam hard!! depending on the vehicle the sound difference will vary alot. for example 2 12s on the 1200.1 will sound way louder in the a car trunk than in an SUV. but four 10s on a 2400.1 will sound way louder in an suv than 4 15s on a 2400.1 in a car trunk. i dont know why the big difference but i asked maxxsonics for the tuning on the amps so all the amps are tuned to run with the subs but even with the same setup, same subs. same amp. same box. same wiring. the sound will vary greatly. my setup consist of 2 12s on a brz1200.1d in a ported box running off a premier deh-p8mp and memphis wire kit. maxxsonics recommened 4ohms subs be run at 1ohms to get the most out of them and remember these amps are cea-certified so im running 600 TRUE rms to the subs and they take a beating. still havent broken them in but have been raising the volume slowly from 15-20-25-and currently at 30 and have had them for about 45days and i know they have a ways to go to break in, u can just feel that its not at its max but once it is they will slam harder.

April 26, 2010

I have one of these in a Jeep Grand Cherokee in a ported box. It hits just as hard as my buddy's two Rockfords! Granted I'm running 600rms and he is Running 250rms/sub. Any one wanting good starter/ budget subs these are your best bet.

Great after LPF filtered

April 22, 2010

I have just one of these in a 1.75 cu. ft. Ported custom box I made to their "Ported Optimal" specs. I'm powering mine with an inexpensive Hitron HA-1000.1 amp wired @ 2 Ohms for a supposed 600 W RMS output. In this box I absolutely LOVE the sound of Rap tracks, for example, by E-40. One thing though... you definitely need to make sure you have the Low Pass Filter on your amp and headunit set properly. The other day I had a higher bass tone try to play thru this thing and made a really bad sound. Did not like it at all. However, I fussed around with the LPF on the amp and set the headunit's LPF to 140Hz and it seems to have solved that issue. Overall I'd say the sound QUALITY was better on the Pioneer Premier Shallow Mount this one is replacing. The Pioneer had a broader frequency range though. But the pioneer was only half the RMS though. So for a slight trade-off on the higher bass frequencies I get a SUBSTANTIAL gain on the low-lows... everything else in my system being the same. My Ford Explorer SportTrac is extremely limited on interior room for a sub box... but if you have a vehicle that can fit TWO of these...man... I don't know how crazy that must be.

good on a budget

April 15, 2010

I bought these subs with the intent of doing a budget system, will admit these exceeded any expectations I had. I have 2 paired up to a power acoustik bamf-2000/1d, wired @ 1ohm which produces what PA says is 1200rms (pa always over does it) so say they're running around 900rms, they sound great, crisp tones, can def feel the bass with the radio at 14, all my friends are amazed by the setup for such a short price, they'll out do any kicker cvr setup My only complaint, the rubber on the sub isn't too thick, and its stitched on instead of glued, something with that much power should be designed a little better but for what I paid, I cant complain

BETTER THAN THE ALPINE TYPE R 12s

December 1, 2009

i have 2 of these on a crunch 1500.1... i know i know under powering them...but they r still getting broken in..about 5 more hours to go..then i can put my other 1500.1 on them....so 2 brutus 12s 2 crunch 1500.1s.. because i have the dual 2 ohm versions of these subs.. but anyways i have 2 of these in my 94 civic hatch..in a 3.56 cube foot box tuned to 34 hertz.. and prolly only about 250 to 300 rms to each sub..and its crazy...makes my windshield flex... its all in the box design.. i say they r better than the type r 12s..because they r a lot cheaper..u can buy 2 of these compared to 1 type r... and personally the brutus hit a lower cleaner bass note.. mine dont hit the really high bass notes because my box is tuned at 34 hertz..but the lows r stupid.. sound awesome on any music...i play rap..bass tracks...country..and some rock..and they never skip a beat.. my buddy has 2 type r 12s on a crunch 1500.1..i built his box also..and we both agree my subs get lower and louder...and these take a serious beating..i free aired mine..when brand new they did 3" excursion without bottoming out!! in short buy these...they wont disappoint!!!! thanks so much for reading my review
