Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
W3v3 (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.
1000 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.
500 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 - 200 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".
87.15 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.
13 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.
Nitrile Butadiene Rubber (NBR)
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.
1.25 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.
1.25 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.
6.65"
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.
11.0625"
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.

Deep, Clean, Kickin' subwoofer!

March 25, 2013

Alright now when I go to reviews, I want to know the variables (car make, box type, box size, etc.). Before I go any further this subwoofer is wonderful and a pleasure to listen to. Now i shall explain WHY it's a great woofer. First off the variables: I have 2 of these subs wired to 2 ohms to an Audioque 1200.1D (both subs are getting about 450ish watts rms, and I don't even know if it's even that because my gain is turned down a bit) in a ported box, one slot in the middle. I don't know the specs on the box exactly, but i do know that the box size and port size are selling the subs short. EVEN with a prefab ported box, these hit accurately, clean, pretty deep, and they don't flutter or boom too much. I have my subsonic on to try and decrease that. Have in mind guys I'm a guy that likes his metal, rock, and music with a kick drum. Hear me out! these subs play any type of music accurately, and that's in a PORTED box. That alone is remarkable to me. And it's a cruddy ported box too! lol. Get these subs! buy them, hug them, love them, whatever you gotta do. Also if you can, get a custom built ported box and get ready to be blown away. These kick. Now for some physical characteristics of the car. I just got them tonight so i haven't observed much but i do know that my rearview mirror is absolutely useless. when i try and readjust it, goes right back down within 3 seconds. I drive a BUICK REGAL year 2000 for your information. I know i packed a lot of info in this review, but i'm very picky, hard to please in certain areas. So being a reviewer, I want to give a review that I'd want to see. As a multi-instrument musician, audiophile, bass lover, and just an average guy trying to have some summer fun with a good set of subs, these are now my go to subs. I've owned or heard sets of Diamond D3 12, Audiopipe TXX-be12, Kicker CVR 12, Power Acoustik Fubar 12, Rockford Fosgate T1 12 (that was a single), 3 Image Dynamic 12s v2, Rockford Fosgate P2 12, Sundown E Series 12, Powerbass L12, Kicker Comp, Kicker L7 15 (single), and probably more that I can't think of, but these give every sub set a run for their money! And beat out 90% of the subs I've heard (majority of them are listed above). Just goes to show you don't need a set of 1000 watt rms subs to bump, you just need a set of these ;) Hopefully this helped. Take Care!

The best subs I've owned.

February 7, 2012

I don't have these ones I have a pair of 12W3v2-4 that I bought from a pawn shop for $100 two years ago. I have them in a ported box powered by a 1100 watt class d Sony Xplod and they pound. Now if the sub doesn't say JL on it I won't buy it.

Bought a w3 a while back for my chevy blazer. It hits hard and it has the cleanest sound of any sub i've ever heard. My friend has 2 12 inch kickers in his blazer and my 1 12 inch jl sounds just as loud. I listen to rock and rap and it sounds great on both. I would highly recommend this sub to anyone.

These Things Are Smooth

August 18, 2006

My Cousin recently purchased a w3 and man these things hit hard and are very tight and smooth even at higher volumes. Barely any distortion at all when at high volumes.It also takes deep notes VERY well for a 12 inch woofer. I totally recomend this if you want a smooth sounding woofer for everyday use. I plan to buy 2 of these very soon.

April 17, 2013

I have had this sub for around 2 months now and i freaking love it. This sub hits so hard and is so loud. The sub is in a 12" slot port box. the box's volume is 1.8 and it is super deep in sound and hits every note. I have a friend with a type-r running at 1ohm and 1400rms and this sub is just as loud running at 4ohms and 500rms.

Best deal on the market

October 17, 2012

I have tried a lot of subs over the last 5-6 years since beginning to enjoy car audio. Some of the names I have used include Infinity Reference and Kappa, Sony GTR, Alpine Type R, Memphis M-Class and reference, and Kenwood Excelon. These are easily the BEST SQ sub for your money, and among the top subs on the market period. They are not going to make you an SPL champion, but they provide more than adequate low-end punch when powered properly.

Pros:

* Awesome quality - right off the bat you can see the time and effort JL puts into their products. Fit and finish is superb, and the clean look of the cone just made me fall in love. Installed in a box with black carpet and it is the stealthiest, sleekest looking thing you'll ever see.

* Superior SQ - the most accurate sub of any I have ever owned. Have a single 12w3 in a 1.3CI selaed box running off a Hifonics BRZ1200.1D (450 RMS output, 50W under RMS) and it does not miss anything. Nearly perfect bass reproduction in all varieties of music (I listen to anything from dubstep, to classic rock, to blues - very eclectic music style and this sub handles it).

*Untouchable value - you will not get quality and SQ like this anywhere else for 180 bucks. Period.

Cons:

*Not as loud as some others - to me, this is not a con. If you know what you are buying, this isn't an issue. This is made to be an SQ sub, and to me the SPL is absolutely adequate. Don't fool yourself, the w3 gets LOW, but it is not going to flex your trunk really hard or crack windows. In my hatchback, it rattles all of my mirrors as well as any change in the center console when turned up. It has even loosened the bolts inside my door skins that hold the hand rests to the door to the point I will need to take the doors apart and tighten them.


To sum it up, BUY THESE. A product doesn't get 4.9 stars on 39 reviews for no reason. Put the right amp on this product and you'll have a system that anyone from a complete beginner to a seasoned audio pro can appreciate. I have mine slightly under powered, in a sealed box and it is so amazing I wouldn't even bother with anything else. I never thought to try one until I heard them at a local shop and decided to research them a little more. Just as an estimation, I could probably give this sub 100-150 more watts and I think it would handle it perfectly fine.

JL has COMPLETELY outdone themselves, and this is far and away one of the top values in car audio history. No vehicle I own from now on will have anything but JL W3's in it.

wow !!! the sound is truely a piece of heaven

January 10, 2011

Okay I've had numerous subs in the past few years from SPL to now SQ now to give this sub an amazing review I have to compare it to subs in its class . I bought a Type R three years ago from Sonic and I absolutely loved that sub but the problem I came into contact with was there was not a very good low bass note. I tune all my subs to specs of the manufacturer. The type are is awesome loud and can handle great power but I recently bought a w3 from a car audio shop in the area as im trying to with a sq setup to be honest I love this sub more than my Type R I have it tuned where JL says and have the perfect JL amp on it. To be honest this sub has hooked me into JL for life. My brother now has the Type r and it is still pumping which is impressive considering I had the subs on 800 rms on a cea certified amp. Yeah the sub is expensive for the watts but the sound that comes out of this sub is amazing it can play country rap rock and rock and will even hit the low notes from slowed down music ....if you want the best of both world sound quality and a sub that will punch you in the stomach get this sub I cant write enough about it !!!!!! JL you make amazing products keep it up I can't wait for my C5 components to come in and make my car an audiophiles dream !! *****

JL Audio 12W3V3-4

July 13, 2007

The JL audio 12W3 is simply an impressive sub, it looks great with its simple yet modern design. The push terminals were a breeze to use yet held the wire in place firmly, and as for sound, That’s the subs most impressive feature, You get an abundance of low bass from a fairly small speaker & enclosure using minimal power. The sub hits hard and clean.

I have three 12 inch JL w3v3's in a custom ported box with a JL audio A1800 amplifier on them. Best brand and speaker out on the market, period.

Quality sound + extremely loud

June 11, 2011

I had a Rockford Fosgate P3 before I had this sub. The rf was a 10 inch in a sealed inclosure. I built a ported box for this w3v3-12 sub according to the specs on JL's website. This thing absolutley slams. I have it hooked up to a kenwood 7205, running at 500watts rms. I have yet to come across anything that hits the low notes as clean as this sub does.

To put this in perspective, i played wiz khalifa's song, on my level, It has some pretty nasty low notes that not many subs can hit. The low notes are so low that not many people can hear them, Well, let me tell you, this sub hit it with a passion, nice and loud.

Nice sub

July 30, 2013

April 3, 2011

This subwoofer is EXTREMELY reliable and one of the cleanest sounding subs I have ever heard. But trust me..with enough power this subwoofer will SLAM. I have 2 hooked up to a 2400 Watt MTX amp and It flexes all the metal on the car. Its great (:

Great Sub for the Price.

November 4, 2010

First of all, I LOVE it. For one of the medium to lower-line subs in their collection, JL Audio has outdone themselves. Sub emits clean and hard pounding (But not overpowering) bass even with just one sub. I highly recommend picking this up if you want clean and balanced overall sounding bass rather than having loudness to showboat :P

Totally Awesome

August 26, 2009

These subs are amazing. Their always crisp and rebound immediately, no matter what I throw at them. Having the JL Slash V2 powering them is the way to go, as its designed specifically to push 2 of the JLW3's.

Hip hop, rap, reggae, rock, drum and base: these subs enhance anything and everything.

High Quality, but Little Power

July 9, 2012

I owned two of these subs and must say that the quality was of these subs were pretty amazing. I wanted them to play kinda loud too, but didn't have enough capacity to do the job. I'd probably spend money on something else that can hold more power and have louder sound.

Notorious

August 19, 2010

This sub hits HARD! I have it powered by a zx500 amp in a sealed enclosure.

When I talked to the sales department at sonic, they called this sub "notorious" for it's hard hitting and clean bass. They were right (as usual). So glad I went with the best. The w3 really is the best out there.

Great Sound Quality

May 17, 2012

I have 2 of these subs hooked up to a JL Audio JX1000/1D and they sound amazing. Without a doubt they are the cleanest subs I have ever heard. When comparing it to my friend's Alpine Type R, the W3 is noticeably not as loud, however, it is noticeably cleaner and goes deeper on all songs.

Tremendously Awesome Subwoofer

January 16, 2012

JL Audio makes nothing but top-of-the-line equipment, and this 12w3v3 is no exception. I have two 8w3v3's in the doors of my 2005 Mustang, and those are so much better than what I was expecting as well, so I decided to get the 12" W3. I built a custom vented box made out of 3/4" MDF with double thick MDF on the front side with about ~2 cubic feet of air space. Believe it or not, I built this for Home Theater Use with a BASH 500W amp powering it, and wow. I LOVE THAT VISCERAL FEELING!! JL Audio fan for life. Thanks, SonicElectronix, for also having the lowest price!
