Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
W7 (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.
2000 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.
1000 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.
3 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".
86.2 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.
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.
OverRoll
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.

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.
1.375 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
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
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.
9-1/2"
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.
10-1/2"
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.

W7 quality

September 13, 2013

This sub is made with quality parts and design. JL holds a lot of trusted patents. All the JL audio haters are just more in love with loud sloppy bass. Put this in a vented enclosure around 35hz and 800-1200 watts rms apiece and you cant ask for much better. Install design is #1 with most all JL products.A bad design and you wont get the most out of it. Im talking the kind of car you have,the box size, Dynamat ect. The thing slams and sounds great doing it! If your into SPL competitions yea, this may not be for you? Never think that this thing cant get down with the others though! Its my centerpiece of a $5000 audio system. All JL audio except a rockford Fosgate T1500.1bdcp amp. The $h1t sounds amazing and near life changing experience! Yea sounds crazy but if you love car audio, buy JL.

Great Subwoofer

December 6, 2012

I recently purchased this subwoofer and all I can say is wow! At first I had it in a cheap pre-fab enclosure and it sounded ok but when I upgraded and put this bad boy in a quality enclosure it really took my breath away (literally). Make sure to get a quality enclosure.

why everyone compares subwoofers to this

September 24, 2012

why is a speaker thats 10 years old worth 550 bucks.... b/c no one has topped it and jl can still get top dollar for it ... if you only have room for one sub and need it louid and clean this will def do the trick may leave your wallet a lil light .. ive owned prob 50 different subs over the years and maybe done 2-300 installs and if i could only have one sub in my this would be... just make sure your tune your amp correctly their a lil picky clean signal and these things are bullet proof

12" w7

October 22, 2011

They are somewhat ovepriced, these subs are made to be a mix of SQ and SPL. When people buy these subs they are looking to be loud while sounding good doing it. I love my W7, just my 2 cents though.

I agree with the review below me

July 22, 2011

I agree with the review below me, these are great woofers but they just don't put out enough to be this expensive. If you could snag one on Craigslist for $250 or so then all the power too you but they are not worth $500 some odd. I would definatly spend the extra $100 and get an RE audio xxx12. I bought a Jl w7 12 and put in a Ported box tuned to 37 hertz and it just felt lacking but then I sold it on Craigslist for 480 and bought a xxx12 and it blew the w7 out of the water! With just one xxx at 2400 watts rms I hit 147 decibels at an spl comp and blew the side windows clean off of my Cherokee! Don't buy w7's they are way too overpriced!

a critic

March 18, 2011

I know most people wont agree with my review, but I have heard many systems in my days and these just happen to be some very very overpriced woofers.
they arent bad, but for the price they should be much better.

2 12 dub 7s in a good box should produce more than a mid 130 on full tilt. the pair I heard never really impressed me, they were decent sounding but lacking for how expensive these are. I can spend 600 on 2 12s and a box and have a much better sound thats much louder than these.

and they are very noisy mechanically, plus this woofer just doesnt have enough b to keep up with large amounts of excursion.

mediocre at best. beatable for cheaper

The BEST so far!!!!!

April 22, 2009

I just got an awesome deal with one of these in a ported box for $275 and it is unreal, the sound quality is untouchable and the bass is so deep and loud, I have it running of a MTX 81001 amp and I am totally amazed. I had 2 12" Kicker CVR's in a Kicker Living Loud ported box, same amp and it is no where near the sound this W7 puts out. Get one if you can afford it and the amp+plus the right power source for as well, make sure to do everything right and don't skimp out so that you can truly appreciate this sub!
