Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
W0v2 (JL Audio)
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.
600 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.
300 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.
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".
85 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.
11.4 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.
Mineral-Filled Polypropylene
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.
Optional (Accessory required and sold separately)
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.

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.
1.375 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.
1.375 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.
5-4/10"
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.
11-5/8"
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.

Freaken Amazing

September 12, 2012

I bought two of these brand new. I have a 800 Polkaudio Amp and an Xslice Capacitor. These hit hard but maintain it so you can still hear the words of the song. I build my own box and i drive a 98 Chevy Extended Cab s10. So i found a custom box runnin 1.97 cubic feet per sub so i tweeked it bring it down to 1.60 sealed which is .30 over the minumum. I absolutely love it. I cant wait to get insurance and get my starter fixed so i can go show these off. The guy who owned the truck before me was a complete idiot. I rewired the whole stereo and even put all my Extra Audio (subs and amp) on a toggle switch mounted in my dash. Quick on-off thing. I am lookin for some better treble so if you have any ideas on what i should get mounted in my doors email me. [email protected]

I just got this sub today, and I love it. Its perfect for what I want. It shakes the trunk, and the mirrors, but doesn't make it sound like my car is about to fall apart. All in all, this sub is LOUD. I have it hooked up to a Planet Audio AC1000, bridged down and it sounds amazing. I bought mine in a JL Audio basswedge ported box, so it sounds even better, but I got it for sale for 200$, spent 500 dollars on everything including install and shop charge. EXCELLENT SUBWOOFER!

Everything about this sub is AMAZING. I had one of these hooked up to a Rockford Fosgate R150-2 in my last ride. It was very affordable and VERY loud. I had a chip on my windshield and watched it split when seeing how loud it would go. I plan on buying this again in the future and would recommend this to anyone looking to upgrade their system.

You cant go wrong with these babies, they really do sound good. I hooked them up to the Kenwood 7205 purchased at this website along with the subs. I previously had the Kenwood 9104D paired up with the some 3012s and let me tell you that by changing to this set up, their is a considerable amount of difference in sound quality. Although their is a trick to getting a high quality system, this is what my system consist of. Kenwood X794 HeadUnit, Kenwood 8404 for mids and tweets, Kenwood 7205 for Subs, 2 JL Audio 12WOv2-4, Kicker DS6930 6x9s, MTX 6502s and the stock tweets powered by yellow top optima battery with 0 gauge wire from Kicker. the reason that I used the stock tweets for the simple reason is that stock tweets are just that tweets, I had a component set by focal and it sounded good but when I replaced them with this set up I was surprised by how much the the sound quality was enhanced. I guess what I'm trying to say is don't be afraid to experiment with your system, sometimes you don't always get what you pay for, some of the stock tweets that they use now days are better than those you pay a arm and a leg for. 2006 Chevy Montecarlo.

I've got 2 12" of these with a Hitron 2000 watt amp and these slap! Neighbors complain of their car alarms going off. These cracked my rear window. Great value. Sure there are some better ones but for the price these slap! Recommend these as starters or if you want deep resonant bass.

These are awesome. I wasn't really sure about them at first, but i decided to take a chance. It was well worth it. I have two of these running on an orion d1200 amp and they pound. I would definitely recommend them if your on a tight budget.

September 2, 2009

Just got one of these bad boys installed in my sentra, all i gotta say is that this thing THUMPS, have it hooked up to an audiobahn a400 and this can handle well over the rms ratings.Actually hits harder than the two 12" w1s i used to own. Just make sure you get a custom ported box to get the best sound.
