Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
W1v2 (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".
87 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.
Silver
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, metallic-finish 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.
Rubber
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.
1.25 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.
1.25 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
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.
5.09"
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.
11.06"
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.

WOW

March 2, 2011

I would definitely recommend these speakers to people. I have to 12"s in these subs, with the JL PowerWedge box. I'm using these subs with a JL 500/1 amp,but at 2 ohms its only putting around 275watts RMS. THEY POUND in my camaro. I was very supprised with these subs. I love JL audio. They have never let me down. Great subs for the amount of power they only need to take. I've owned Kicker CVR's, L7's, Comp's and many others. these are good subs.

You have one 12???

December 26, 2012

I have this sub in a huge 2.5 cubic feet vented box tuned at 50hz. I'm running a 600w (300rms) amp at 4 ohms to it and this thing is literally an eyeball rattler. If I'm in my driveway and I have it turned up the windows on my house shake and so does the china cabinet. It hits the lows like they are nothing while still providing superior sound quality. This thing is rediculous. Only con is the color. It is an ugly grey color. But jl gives you a metal grill to go over it which hides it.

Compared to the w0 series the w1 demolishes it. It is worth the upgrade. A friends car had 2 12" w0v2s in a vented box and you could only feel the bass. There wasn't much sound to it. But my single 12" w1v2 blew it out of the park.

Amazing sub!!!

January 16, 2012

I bought this 12" sub because I know JL Audio is always a top speaker in its class. I used to own a W6 many years ago and this speaker I think sounds better! Very impressed and overwhelmed that it sounds this good, shocked actually! Running 270 W RMS to it in a sealed 1.20 cuft box and it drops!!! But this sub is on spot! Not too over bearing but gives your incredible low sound and depth to your music.

The only choice

March 23, 2012

JL Audio is the choice if you're looking for clean, crisp and tight bass. This sub is very responsive. It handles a wide range of frequencies with ease. To get the most out of JL, simply follow the recommendations from JL. Build the box to spec and give it the power it calls for - don't over or under do it.

JL is the best and there is nothing more to be said.

This sub is built very well and like all other JL audio products it has great sound quality. I had 2 in a 4 cu. ft. box and they sounded great and had pretty good excursion even thought i was only giving them 200 rms a piece. I recommend for an high entry level setup.

W1's sound awesome!!

December 27, 2010

Got 2 of these bad boys installed in my 09 Silverado Crew cab. Pushing them w/a JL Audio G1700 (700 watts) and boy do these subs sound way better than i expected. They are down firing under the back seat and using factory dash. Havent cranked it up all the way and they are already super loud. Wanted W3's but t glad my choice were these. They hit lows and highs w/o a problem. Guys at the audio shop were very impressed. All the customers in the shop were admiring the sound and giving compliments on the quality. JL Audio definetly but quality in all there work. Believe me ive had kicker, rockford, infinity, power acoustik, audio bahn, mtx, panasonic. and several more but nothing like these subs. Very happy customer and for the price $100 bucks, u cant go wrong.

I wasted my money.

August 9, 2010

I have always wanted JL's growing up. I bought a pair of these W1v2 subs, and i was so disappointed. The magnets on them are slightly larger than the magnets on my Boston 6x9s. The cone wasn't stiff at all and when i hooked them up, they were weak and barely moved the air. The sound quality was distorted and muddy. I had them hooked up and tuned properly to my amp. I sold the W1s and thought "maybe I'm not happy because they are their lowest level subs" so i got a pair or w3s and i was just as disappointed. Basically, an alpine type r is 1500 watts and costs $120. A JL w6 is 1200watts and costs $500. I'm way happier with my new alpine. JL is way overrated.

Satisfied

March 3, 2011

I have one of these hooked up to a Tarantula 800w Soundstream amp. Its dialed about half and hits great. I'm looking to get another. The Soundstream amp is 2 channel and would def handle both great. One negative is in a small car (99 mustang), Dynamat or something is prob necessary because when I turn up just one of these subs it rattles the trunk too much. Don't get me wrong the sub hits and remains low and at good pitch its just the car that rattles. I usually pull the seat down in the back (exposing the trunk for a little more resonance). The sound quality remains even at very high volume. One thing else that you prob would wanna know is that yes these subs hit and sound great even at double pedal metal bass drum or slow hard hitting rap, but the thump outside the car isn't as loud as you would expect or at all. But personally I don't care that I'm not that d*****bag that thinks he has a nice system rolling down the street.

Ok Sub

October 6, 2010

This sub is an average sub if that... The sound quality is alright but at high volume it starts sounding bad.... This sub IS NOT A POUNDING SUB either, you wont be heard outside your car at all. I had two hooked up to an 800 RMS amp and i just switched the subs, now Memphis subs and Im happier. If you want to feel bass and shake the cars next to you at stop lights DONT get these. If you want clear, good sound without vibrating bass then get them, especially here at Sonic. These subs aren't worth the retail price, so buy em here.

Good sub just dont put true power to it

June 2, 2010

Blew one out on the first day of use. Don't put the "TRUE" RMS rated power through these. I think they expect you to be using one of those cheap amps that claims to make this power but really makes less. It is a good sub for boxes that don't have much back spacing, like in a truck. Just keep the power low on these suckers.
