Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Champion (Pioneer)
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.
1400 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.
400 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.
Single
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).
20 - 220 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".
94 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.
Injection Molded Polypropylene (IMPP)
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.
Elastic Polymer
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.

Bandpass
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.
0.85 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.
1.75 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.
2.0 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"
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.
11-1/8"
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.

Slammin'!

May 3, 2012

2 of these setup in my Samurai powered by 750RMS amp. Anything past 50% will make everything rattle! Get some dampener if you have a strip rig. I'd recommend it all day. If you have the extra 10 bucks, get the DVC thou so you can run it at 1 ohm (with compatible amp).

Just buy this and dont look back.

For the price, it hits

January 3, 2012

Once the sub is broken in, it sounds clean and hits pretty nice. I am running 350 watts rms in it and the sub's max rms is 400 watts. The amp pairs perfect with the sub. But if you want real bumps, this sub is not enough. Get 2 or buy a stronger sub for more money. I don't like rattling my car or drowning out the mids and highs, so this sub is good for me.

I have 2 of these hooked up to a 1000 rms monoblock amp running at 2ohms. They are in a ported box in my 1995 Nissan Maxima and these things pound. People at my school hear me coming. Would recommend these to anyone looking for lots of bass without breaking your budget.

Sounds Great Just What I Was Expecting

March 11, 2013

Currently I have two hooked up to my kac-9105d wired to 2 ohms running 900rms total. I've got my gains set fairly low because my alternator is bad but they still sounds great! Ported at 1.5 each they produce great low bass. It gets cold here in colorado, once they warm up a bit theyll bump all day long.

These subs hammer. I have 2 of these in my s10 in a 1.2 cu box or each sub. Then hooked up to a 2000w mono. Running 450 to each which just above rms power which is good for subs. And these things pound. I've already gotten pulled over for having these things. I see no cons about them yet. They are loud, clean, and easy to clean. All materials seem durable and I've had them for 6 months with no issues. I highly recommend these subs.

I have had this sub for about 3 months and have been satisfied. The price is good, but it's not enough if you want really hard hitting bass. I'm running it off of a 400w rms amp and it does the job if you don't like to rattle your whole car.

Great sub for the price

March 18, 2012

I bought this sub over the summer along with a Boss amplifier and a ported box from Best Buy. The reason I wanted a sub is because I had simply no low end in my car (Acura RSX), as it has four 5.25" speakers. This sub certainly did the trick. It may be because it's in such a small car, but it delivers quite booming bass and I've never even turned the amp all the way up. Once it gets broken in and tuned correctly it sounds very clean, even with my ported box. I've enjoyed it for about 9 months now and had no issues. Overall, great sub for the price. I don't need anything louder but if you're looking to set off nearby car alarms you might need two of these or more powerful subs.

Amazing sub

February 6, 2012

I have this wired to my Pioneer GM-5500T amp in a vented box in the trunk of a 95 thunderbird... and this thing hits HARD! Just as good as my friend's 15 inch apline, but not quite as loud. But it is hard to believe this sub is only a 12. After bumping for 15 min my heart started to hurt haha. It has the perfect amount of bass too, it wont distort the rest of my music. Buy this sub if youre thinking about it, really inexpensive but hits wayy harder than you ever will expect.

I have 2 of these subs in a custom box that vents the bass through the rear armrest in my BMW cabriolet. They are hooked up to a Rockford Fosgate p-800.4 amp getting 400rms to each speaker. These things HIT. If you want a great sub without breaking the bank, these subs are for you.

Go ported if you want loud. I used sealed for midbass purposes only. The Pioneer amp should be all you need. Put the 12's in 2.5-3 cubic feet each tuned to 40 Hz and you WILL hear a HUGE difference.

I got this sub with an 1,800 watt amp and it works great. Of course you can get a better system, but for a single sub and monoblock amp, this hits really hard. My friend could hear my car from down the street, not even at full volume or bass. If you want a GOOD affordable system, get this sub. Other high end names are just overpriced. This sub will shake your car, while allowing almost all other sounds to be played along with it.

Decent subwoofers

December 25, 2012

I owned six of these subs. they sound really good in a good enclosure with the right amp and cd player. I have two in a 2008 malibu ltz with a ported box on a m500 with a pioneer tv deck and gave the car and sounds to my girl. it hits damn hard for a girl. SO I installed the other four in my 2000 buick regal in a sealed box and a power bass 3000d with a pioneer and it hits real hard it would have sounded better if i would have made the box bigger with ports holes but it sounded so good a guy gave me 600 dollars for it on spot at my job when he heard them and I only had them in a week! I only paid 350 for all four and the box. impressive. so their worth buying

I bought 2 of these for 99$ and everyone doubted they're good quality. I did the break in period. I had one guy tell me they wouldn't hit good, and i never played them after they got broken in. My volume was on 15 and i cracked both tail lights and had police visit my house. I'm currently running the subs off 2 different amps and a bandpass box. I cut bass boosted on and shatter my bandpass box! I recommend these subs!!

This sub is absolutely amazing! I have one hooked to a Boss 1100 monoblock amp in the Metra ported truck box and it is a perfect combo in my jeep. It hits super clean almost as good as a Fosgate but not nearly as expensive. Its even loud with the top off the jeep which is awesome. I would have got two tens of this series but that would tear my car to shreds. Totally worth the money for sure!

Great BANG for the Buck!

November 11, 2012

I purchased these because my teenage step daughters had blown up a pair of JBL subs from another well known supplier. Come to find out the problem was poor workmanship on the part of the speaker manufacturer. I blamed the kids for kicking the system too hard, oops sorry about that!
So I looked around to find a cheaper pair that would work. What I got was an excellent pair of subs that I wish that I had started out with in the first place! Sound is great and no quality issues to deal with!
I would highly recommend these if you are looking for a quality produce at a fair price! Teenagers are happy now too!
