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
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
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.
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.

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.

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.

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.

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.

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.

I ordered this Subwoofer from SONICELECTRONIX.COM recently and got all that I expected and more. JL AUDIO definitely has it figured out. I have one of these hooked to 200W in my single cab 1989 Chevy Silverado and it bumps well. Bass is very nice, but if you want low..low....low pitches, you need to buy the 13 inch or 15 instead.....kicks hard though!!!

Decent sub for starter system

June 7, 2006

the sub knocks, so its nice, its not something you would want to invest in getting more then one of, but it's the kind of sub you can get as your first sub and down the line upgrade. i just got mine and plan on having it for around 3-4 months before upgrading, this sub is a good deal for the price, get at least a 500wrms amplifier to power this, reccomend a 2 channel amp that is bridgeable then use the 2ch amp on rear speakers after you upgrade sub / amp

Awesome woofer JL - bregging rights

September 24, 2012

I recommend this woofer to anybody. Its a 130 bucks worth of pure enjoyment. I bought one used for a subsitute until my w3v3 gets here. Wow? Awesome. I know they recommend 1.75 but My box is a 2 cubic foot slot ported enclosure tuned @32hz. This woofer is blowing me away beyond expectations. IT ABSOLUTELY rumbles the LOWS with sound quality ALL DAY and THUMPS really hard and clean also. Not to mention im powering it @ 4 ohms with about 400-600 rms... Begs for more in this box, even though its above air spec. BUY!

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.

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.

very good beginner sub just plug and play

CONS-mids are decent, highs suck
not worth $229

Great Entry Level Sub!!!

February 15, 2010

Great Subwoofer JL makes great stuff, I would definitely recommend this Subwoofer or any JL product. My buddy has had these subs for like 6 months and he loves them. However if your looking to beat down the block these are NOT going to do that, if you want some hardcore bass go with the JL W3V3. Sonic Electronix is the best site out there, Sonic is way better than any other site, plus sonic has the best customer service, the guy I talked to (Ricky) was one of the best and most knowledgeable customer service reps I've ever talked to, unlike other sites customer service people that dont know anything about subwoofers(wont mention any names we'll just say there site has the initials CF). Sonicelectronix.com gets a 10/10 from me and the Subs get a 9/10 and CF gets a 1/10.

All JL Subwoofers that I have owned work great. I have a 13" JL subwoofer in my GMC Jimmy. Two 10" JL subwoofers in my Chevy truck. Two 12" subwoofers in my 1967 Mustang. Very satisfied ! Lots of bang for your bucks.

Terrific sub with a proper box & properly powered

July 2, 2012

Great sub. Very happy with my purchase. I have mine in a custom made sealed box. Nice, clean bass with exceptional sound quality, regardless if I'm playing Pink Floyd or Snoop Dogg in the stereo.

As with any other sub, the sub box should be custom built to JL Audio's recommended specs (whether you go sealed or ported) for the best sound.

Its also important to follow JL Audio's recommended power range, which is not much at all for this sub. They recommended 125-150 for this sub and my amp is running about 180 RMS watts or so. The sub sounds terrific with this amount of power and its plenty loud.

As others have said, its not a sub that is going to rattle house windows or disturb peaceful neighborhoods. That's a good thing, IMO. I don't need a sub that pounds that hard. If you're like me, this sub will be perfect for you.

Sometimes the right sub in the right box means EVERYTHING!

February 17, 2012

I have an Atrend A152-12. For those of you who don't know; 12 inch dual downfire bedliner enclosure. Pretty much the best made for the silverado. Issues--.97 cubes per side. There is plenty of depth but good luck finding the correct sub. I WAS using some old school 12w6v1's with heavy polyfill. There was a noticeable bump at 100-60hz and then a sharp roll off. That said; those subs were perfect in the former 1.25 cube box. So I researched and researched; drove myself crazy looking at graphs in Win ISD pro with different TS parameters. So I decided I had to just do this locally so I could take it back. Well, the point is this sub is PERFECT for the box with medium polyfill. I am back in the high 130's SPL wise and clean as a baby's bottom! I mean CLEAN! Driving these with a JL Audio J2 500/1 and highs with a JL J2 320.4... Head piece is a stout but aging Alpine CDA-9885. Now to get rid of the craptastic MB Quart PVI216 components in favor of some Image Dynamics Ctx65cs's and the transformation will be complete!!! Oh yeah in short... You got this box? Buy these subs... Your research has already been completed.

sounds good

I like this sub, it sounds clean hooked up to my fosgate amp. Doesn't need allot of power to push, i have my gain dialed way down. It does hit the lows pretty hard mids decent amd the highs ok. pretty good bass range for such a low priced sub. Great entry level sub.

Best Answer: No. The only way you can wire your sub's is to a 2 ohm load on the amp. This amp runs 375w RMS at 2 ohms. It would be providing about half the power you need for both your sub's.
