JL Audio W3v3 Series Subwoofer Driver
JL Audio W3v3 Series Subwoofer Driver

Easily the best selling subwoofer driver, next to the W6v3, the JL Audio W3v3 provides phenomenal performance at moderate power levels with superb sound quality. The W3 series is in its 3rd iteration, embodying the series' pursuit for providing outstanding output and world-class sound quality. This is accomplished by utilizing a whole suite of advanced technologies originally developed for JL Audio's flagship W7. An Elevated Frame Cooling design helps in delivering enhanced power handling and sound quality. The DMA-optimized, long linear excursion capability minimizes distortion and increases output, while multiple patented technologies enhance performance and reliability. Such advances make the v3's the best sounding, most reliable W3's yet.

Although the W3v3 Subwoofer can be driven with as little as 75 Watts, for best audio performance it is recommended to run an amplifier capable of between 175 - 250 Watts of continuous power per driver, like the JL Audio JX250/1 or JL Audio XD300/1v2. In addition, these subwoofers are optimized to operate in either a ported or sealed enclosure, needing only 0.30 cubic feet of air space in a sealed box and 0.35 cubic feet in a ported/vented enclosure. (Specific dimensions and figures can be found in the user manual, linked further below.)

Like many other high quality JL Audio products, all W3v3 subwoofers are built in JL Audio's Miramar, Florida factory, with extreme precision and top-notch build quality. Its this attention to detail that delivers the JL Audio quality and performance we have all become accustomed to.

JL Audio Patented Cooling Technology

JL Audio Patented Cooling Technology

JL Audio's patented Elevated Frame Cooling design delivers cool air into the heart of the subwoofer in ways no other manufacture's driver can. Purpose-engineered slots located directly above the top-plate stream air to the voice coil. In addition, the upper surface of the top-plate is directly exposed to this air flow, whereas on a conventional design it is isolated from this flow by the lower flange of the frame. This technology not only increases thermal power handling, but also sound quality by minimizing dynamic parameter shifts and power compression. In plain English, this driver keeps itself cool so you can play your system longer, safer and without having to worry about frying the motor.

Extraordinary Linearity and Control

Tight, Clean, Articulate Bass

DMA is JL Audio's proprietary Dynamic Motor Analysis system and is aimed at improving dynamic motor behavior. As a result of DMA optimization, W3v3 motors remain linear in motor force over an extreme range of excursion and also maintain a highly stable fixed magnetic field in the gap over a wide power range. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass. Its main catalyst is the driver's Ultra-long Voice Coil, that allows extreme linear excursion, phenomenal power handling and control, control, control.

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.
8"
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.
250 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).
28 - 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".
83.24 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.
10 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
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.
0.30 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.
0.35 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.
4.63"
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.
7.09"
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.
35.14 Hz
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.
15.29 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.
0.467
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.
0.501
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.
3.77 ohms
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.

Great Sub

December 22, 2011

Have 2 of these underneath the backseat in a F-150 2010 extended cab. Great sub hits the notes very LOUD!!! Great sub for having no space to put them. Have it setup w/ JL audio to get rid of factory speakers and you can hear every note high and low. Worth the buy. May be worried about not getting the bass you want. DON'T worry about that at all. Get a great box too and they work superb.

Very Solid

March 27, 2012

I am very pleased with these subs. I have 2 of these in my 03' f150 supercrew and these fit under my backseat perfectly without any real modifications. my amp is a Alpine MRP-f300
SOUND: these subs really do sound great. They have what i would call "grown man bass." Your probably not going to shake your neigbors cars mirrors but they provide a very solid thump without being flooded or sloppy. I have always had 2 12's in all my previous cars and while these don't hit as hard as those did on the very deep lows they still hit amd I would say it is rather close and these sound better.
SIDE NOTE: As always it depends on what amp and whatnot you have running your speakers but with these i can set loose change on my console and watch it move with the bass where i have never really been able to do that before even with my 12's
CONCLUSION: if you are a teen and just what the most flooded. ratteling bass you can find these might not be for you. but if you want a very clean sound that will still shake your seat and fit conveniently in a tight space i would highly reccomend. .
*Only giving 4 stars for look/design and durability as i never see speakers and have only had them for 6 months so can't fully speak to durability.

8" W3?

November 18, 2010

These really do not sound like 8's. They slap hard and people are always amazed when they hear them. I have 2 8 W3 in a sealed box in a nissan frontier crew cab and they hit so hard. I had someone come into my car not knowing i had subs and asked them what they sounded like and he said he thought it was a 12 in a large box. No one believes they are only 8's until they see them. I definitely recommend this to anyone limited in space and wanting the most boom for their buck

i have a lexus sc 400 these speakers with components and all fit flawlessly and offer a sound that is truly extraordinary, i was advised to buy this brand with guaranteed satisfaction, and i openly admit that is what i have. Complete satisfaction and super pounding power, highly recommended, state of the art is JL Audio, and i got a 8 inch sub instead of 10 i was very worried it would not provide the bass i wanted wow it vibrates the mirrors and seats and thumps!! more than expected and surpassed 2 friends 10 and 12s they had

Super 8

February 9, 2012

2008 Wrangler Unlimited. Made spacer so that the 8w3v fits in OEM enclosure. Being fed by Cadence XAH250.2 mono. If you are reading the reviews, you know the praise for this little thing. No BS, this little thing is awesome for an 8. In previous vehicles, I've had a single 10 and a single 12. Both Polk db's. The JL is as loud as the 10 and musically it sounds better than both the 10 and 12. Both db's sounded "messy". This one is very precise. Definitely worth they extra money and for this particular application, it is perfect.

thats an 8?!

March 13, 2011

Skeptical is the first word that comes to mind when I think of my purchase of this speaker. I have only had JL in any car I've ever owned, but never an 8. I knew the quality, but had never heard one before. Well, now I have and oh my, is it amazing! I built a custom box and hooked it up to a RF 330-1 amp(also awesome) and am now in audio bliss. These little speakers hit every note thrown at them and they do it precisely and effectively. They need very little power to work so thats a big plus to the cost conscious buyer. I have one 8 in a 2010 toyota venza and couldnt be happier. Good work as always jl!

JL AUDIO 8W3V3-4

November 12, 2010

Purchased (2) of the subwoofers from Sonic Electronix via Ebay about six months ago. Since installing them they have been one of my best car audio purchases that I can remember. I've gone through 4 different systems, ranging from 15, 12, 10 inches. If your looking for a compact woofer that is backed by one of the best audio companies out there this sub is for you. In a small ~ 1 cu ft sealed box these subs hit just as hard as a comparable 10" woofer, given proper power.

I have done business with Sonic Electronix for almost four years, and I will continue to use them in the future.

November 1, 2010

I bought this speaker about 6 months ago. My intention was just to upgrade the speaker in my factory installed sub-woofer box. Needless to say, this was the best upgrade I have EVER invested in! The sound is stunning, the lows hit amazingly hard and the mid punchy bass is the perfect complement. On top of that, the box I have isnt even ported and I'm only running a 250 watt mono amp! I'm perfectly content with the sound and I haven't even pushed the limits yet. I highy recommend this Sub.

What a great subwoofer!

August 29, 2009

I replaced the stock amplifiers and subwoofers in the doors of my 2005 Ford Mustang, and let me tell you...Make sure you get sound dampening material for these subs!

These subs hit hard, but yet sustain the lowest of notes. I mostly wanted to get sound quality, and I knew JL Audio had a reputation for sound quality---and they sure live up to it!

Overall, this was a tremendous purchase, especially for the price! I highly recommend the JL Audio 8w3v3-4.

Awesome sub!

August 14, 2013

I have this sub in my Audi S4 and wanted to not sacrifice trunk space. I had a custom box built in the compressor and tool box storage area. The airspace needed was less than .30 cu ft! You would never know the sub was in there unless you pull the panel off. I run two sets of components and this sub off my Alpine PDX5 and sounds amazing! If you are looking for a reliable sub with good sound for little airspace, then this is your best option. I did all the researches and this is the best bang for your buck. You won't be disappointed.

If your looking for tasteful sound in a confined space then this is the sub for you. They really do well in small enclosures. You can find specs on JL's website that make them come to life. You also won't find them any cheaper than Sonic.

July 27, 2011

I have 1 JL8W3 in my sierra extended cab w/ factory Bose and this tiny little speaker rocks. It brought the complete system to life. If your tight on space I'd say this is the way to go!

JL Audio 8w3 is a great product!

October 8, 2010

I had a 10w3v3 in my vehicle, but just wanted to try an 8w3 just to see how it sounded. I was very pleasantly surprised - the sound quality and clarity of bass guitar notes was much better with the 8" than the 10". I had to turn the gain up a couple clicks to get the same volume as the 10", but that was no problem.

Still trying to understand its value.

October 11, 2013

I used this sub with a JL JL250/1 and I'm having a hard time figuring out why this sub costs so much. It has great SQ, hits high bass well. I've seen other 8" subs for around the same $ or less that offer a lower frequency range. Besides that, before this sub, I tried a kicker c88, RE REX, and I'm just confused why this sub is more than double the price of my others performance wise they seem to be relevant. I would not buy again.

Great for tight spaces and SQ

March 22, 2010

I have two of these in a custom down firing box under the rear seat in an 07 Avalanche. The box fits under one side of the seat and extends to the center powered by Alpine pdx 1.600 amp. Bass is very clean and strong, hits every note and kicks the back of the front seat. Sounds great but leaves out most of bass under 30HZ. Sounds better played moderate to loud. Great for SQ set ups. Recommend three for lower bass or ported box. Genre=Cont Jazz, R+B, Rap. Neo, soul blues.

Subwoofer JL Audion 8W3V3-4 Review

September 18, 2013

This was placed in a 2002 Toyota Avalon as a replacement subwoofer. We amplified it with a JL Audio amplifier 200W already installed under the rear parcel deck.

Pros: Excellent Service from Sonic. No problems whatsoever with shipping, packaging, anything. Subwoofer performs flawlessly. Well made. Robust magnet.

Cons: None. Simple transaction and install. A little pricey.

little sub....HUGE BASS

April 6, 2010

Wow. That's the first word that came to mind after i installed this little wonder. JL already has an outstanding reputation for sound quality and power especially when it comes to their subs. This 8" w3 series is no exception. I was considering a smaller sub because of the cramped space i have in my jeep wrangler. I researched which sub i wanted for my jeep for a few months before buying this one, so i know what this thing is capable of and the quality sound it can produce. I needed a sub that produced maximum sound with minimum space requirements; this sub definitely meets and surpasses this criteria. After installing this sub in a sealed box that meets the performance requirements, it took up hardly any space and sounds phenomenal(when matched up with the proper amplifier). The 8w3 comes second only to the 8w7(which is pricey) and it sounds like two 10's, if not better.
