Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
W0v3 (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
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).
22 - 250 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".
85.64 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
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.
Foam
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.

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.
1.37 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.
1.37 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.
1.75 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.
5-7/6"
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.
11-1/16"
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.

Fantastic subs

January 8, 2014

I bought one of these subs for my Nissan Armada, being powered by a JL amp and this 12 inch sub rocks. I have it in a sealed box and you can hear me from blocks away. I would highly recommend this sub and any JL product for that matter. It is all I ever use and JL has never done me wrong. As well as Sonic Electronix, I get all my car equipment and never have had a problem with shipping or product condition and their prices are the best.

JL 12W0V2

June 10, 2012

So about six months ago I ordered two of the 12 JL audio W0's. I spent a bunch of time scrolling through subwoofers and many hours reading the facts. After a few days to think about it I went with JL. My brother has some W3's and they are awesome! After the hook up, break in, and tuning period was over i finally was able to crank these babies up. I was completely shocked!! 150 watts of Kenwood power going to each sub at 4 ohms and in a custom dual chamber ported box at just over 30hz and these subs will go so hard!!! Very loud for the hip hop music (which is what I mainly listen to) but will keep composure and remain so precise. Perfect for any and ALL music! All in all these subs are awesome, anyone who knows JL knows that there is nothing but quality when it comes to their products. Definitely a good buy, worth it!!

beast

May 15, 2012

These subs are beast my 2 JLs hit harder than my brothers 3 kicker comps and his amp is a class D and mine isn't.. If you got the cash definately take the W0 over the WX worth the extra cash. I checked all around before I bought my subs here at sonic and they got the best price anywhere.

May 9, 2012

I bought two of these, wired them at 4 ohms in a ported box with 250 rms and they are loud and clear. I love these subs, they were cheap and couldn't sound better. I used to have two Kenwoods hooked up to my rockford amp but they ripped shortly after. They had roughly the same specs buy the jls go louder and sound a whole lot better. Very good subs for the price

sounds great

March 15, 2012

This sub sounds great, can hear from a block away. Only downside (to mine at least) is that it blew in 1 month, dont let that stop you from buyin it though. This sub is great for the money and warranty will cover any problems.

Strongly recommend these. Have 2 sealed hooked to a zx750.1 over powering each by 75 watts and these have been banging for along time. I wouldnt recommend under powering these by 250 each at least give them 300 each. If you over power them in a sealed enclosure they won't blow. They'l eat it up and make your system sound awesome.

If u want a budget sound you just need to get two of these hooked up at 2omhs with a JL JX500/1 amp running 2omhs. Will get good sound with ported box.

March 20, 2012

Okay, so normally I can care less to review anything but I decided to since all these other reviews pretty much suck. The subs pound good. They are very bassy with alot of thump. They are very durable subs and a league all in their own. Got 2 of these in a Probox with 1000 watts to them and they beat!!! The only bad thing I would say about this sub is not a lot of highs but incredible kind of lows.
