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.
8"
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.
3 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).
23 - 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 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.
19 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.
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.
Foam
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
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.
6.83"
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.
6.94"
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.

Great Sub!

September 29, 2010

Great Subs. I got the 8" to fit in my Dcab Tacoma. It sounds great for an 8" sub. Still fills out nice and low. It is in a sealed box and is very accurate and tight sounding. Very comparable to the old Rockford Fosgate HX2 Power series. Would by again.

Awesome sub, well worth the money. Beats the 12" and 2 10" subs I had in my truck before and sounds waaaaay better. Have it in a slot port box.

ol yea, lil bulldawgs

February 7, 2010

If you think you need (2) 10's or 12's forget it.. I have (2) 8w7's on a PPI D3000/1 feeding it appox 1000w plus @ 1.5ohms talk about SQ/SQL. Yea, the JL w7 line is expensive we all know that BUT when you have (2) 8's that sound better then (2) 10's/12's (maybe NOT louder but BETTER) thats when JL's quality shines. Port these lil bulldawgs and sit back and enjoy. One ported can do it, but two will be perfect. The key too these are properly tuned enclosures and feeding them nothing less the 500rms per. I have these in 2cf after displacement, tuned to 34htz.

JL Audio is the ONLY option

February 4, 2010

Once you try JL you will never want to buy another brand again. I previously owned 2 JL 10" W3's and was very nervous about having to downsize my system because of space. This 8" W7 is amazing! W7 is the only way to go, especially if your looking at a little 8" woofer. This thing kicks @$$!

Best 8" sub

December 30, 2009

I have an 08 chevy crew cab, I have installed a quality sound system in every vehicle I have ever owned and of coarse wanted another. This one was a challenge due to the limited space under the seats. But these 8" subs are beasts in small size. I actually place two in a single chamber box with a single slot port tuned to 42 hz with available power of 800 watts each. I am amazed in the clarity and extension these subs deliver. I'm in the 140's db with pure clean sound. I can't believe that they hit the 30 hz music so well too! Just awesome to hear! I looked at allot of 8" subs and these blow all those away! Plus since they are 8" there is almost no roll off between my mids and subs. You can set the crossover to 80hz for a great blend!

JL Audio 8W7-3

November 16, 2009

Bought 2 of these and built a slot port enclosure out of mdf according to the factory specs. I am using a 1000/1 v2. Just broke em in and they hit so hard for a set of 8's. All my rca and power cables are monster 400 series and the clarity and sq with these subs is amazing. Only downside is I need to go buy more dynamat. Make sure u get the bass remote. U need it for quick adjustments between rock n rap.

Hammers Low!

October 24, 2009

I purchased this on this website (www.sonicelectronix.com) I had just received it yesterday. Going through the break in period with it right now. I built the enclosure myself using 3/4" MDF using JL Specs. I currently am running this in the vented enclosure off of about 80 watts of Rockford Fosgate. The sub really shines through on the Very Low End! Sounds a little weak currently with rock songs but again its only receiving about 80 watts peak for break in. Plan on running either the JL 250/1 or JL 500/1. Overall I am very very impressed, Have I had louder setups for less money? Yes, but they didn't have the clarity of this 8. Have I ever heard a louder or cleaner single 8 setup? NO. I would say if your looking for very clear yet loud low end this is for you. 2 of these on a JL1000/1 would slam! BUY IT YOU WONT REGRET IT. As far as price, sonic is the cheapest.

Big Bang

October 13, 2009

I was looking for something compact but hit hard. I knew the long line of jl products were quality products. I bought 2 JL 8W7-3 for my 96 impala and wow do they hit hard. I always stick my friends in the front seat to see how they feel and then I show them the trunk and they are amazed. They had no idea some little subs like these could even sound like that.

My order was packed and shipped the same day my order placed. Very quick arrival time. Extremely high quality product. The JL Audio 8W7 is AMAAAZING. Previously I owned two 10"W3's and was worried about having to downsize in my new vehicle to an 8". But JL has definitely pulled the rabbit out their hat! If you did not know that it was only an 8, you would guess it was a high-end 10 or a nice 12!

One Amazing 8

July 19, 2007

I have owned about ever 8 on the market and i have to say this was one of the most impressive 8's i have tested. The excursion on this little thing is crazy. The sub will take way over rated rms with no problems (800-1000rms depending on box size) The subs hammers the lowes in a nice ported enclosure will still sounding very clean and having alot of out put. Little price, but honestly worth its price tag.

People do not realize that Peak Power is not important when it comes to buying a high quality sub. I have heard these subs and they hit extreamly hard for an 8" sub and they dont break your bank when it comes to buying an amplifier. Also you can get many more subs for the same price but this sub works excelent with minimal space and low wattage. JL has always run well on low wattage systems.

lots of power for 8

December 23, 2005

this is probably one of the most powerful 8" subs on the market. it is hard to believe it is only a 8" plenty of bass when hooked up to a 500/1. I like the tightness and quickness of the 8" sub compared to the larger ones.
