JL Audio's top-of-the-line subwoofer

JL Audio's 30-plus years of research into car audio design has produced the legendary W7 subwoofer, and you'll hear that engineering in every note. JL Audio applies its advanced technologies separately to each W7 subwoofer, so each size sub is a unique design with its own motor and suspension system. You'll hear smooth, audiophile-quality bass output, even at extreme levels.

Advanced technology for superior sound

W7 subs feature six different patented technologies which give them their edge:

  • W-Cone™: a dish-shaped outer cone is supported by a second W-shaped inner cone attached to the the sub's voice coil structure. The light mineral-filled polypropylene cones respond rapidly for accurate, distortion-free bass without unwanted coloration.

  • OverRoll surround
  • OverRoll™: the oversized polyether foam surround extends over the edge of the mounting flange for more bass output without sacrificing linearity.

  • Floating Cone Attach Method
  • Floating Cone Attach Method (FCAM™): cone-bonding technology keeps the voice coil centered during long excursion.

  • Spider attachment
  • Plateau-reinforced spider attachment: a collar on the voice coil eases stress on the spider for extended excursion and improved reliability.

  • Elevated frame cooling and pole piece
  • Elevated frame cooling and cross-drilled pole-piece: cone movement pumps air through vents in the frame and machined holes in the pole piece, keeping the voice coil cool.

Reliable performance and accurate response

JL Audio designed the 13.5" dual voice coil W7 subwoofer to maintain linear motion during extreme cone travel, so you get a high-performance sub that's incredibly reliable. You'll find a strong cast-alloy basket and ultra-long voice coils among many impressive features which help this sub deliver profound, natural, and lifelike bass. This 1.5-ohm DVC sub should be matched with the proper amplifier and wiring to ensure optimum performance; call 1-888-955-6000 if you have further questions on powering your W7 subwoofer.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Subwoofer will not disappoint!

Written by: BDZ from Chicago, IL on June 9, 2011

This subwoofer is seriously impressive. I was skeptical of whether one 13w7 will be sufficient considering I previously had three RF P3s in a ported box. But this one speaker is seriously much louder and better quality than my previous setup. I will caution prospective buyers to invest $200-400 in having a custom box built by professionalss in order to unlock this beast's true potential. I will also caution buyers that this speaker is way louder than I previously thought considering its reputation as a SQL driver. In fact, the SQL is probably less than what I thought considering its reputation. Don't get me wrong, the sound quality is impressive but this driver puts out some serious bass. I guess I thought I was going to get an Alpine or Boston Acoustic's experience. However, I got a speaker which is just as clear but much louder. I recommend pairing the speaker with the JL 1000/1v2 amp which is perfectly built for this driver. Lastly, I would recommend that prospective buyers look around on the internet where this speaker can be found for around $650 and the amp also goes for around the same.

This is an amazing sub. If you need a sub with deep bass that will hit hard,
this is definitely it. I have my 13w7 hooked to an 1000/1 and I plan to buy
another w7 and 1000/1. This definitely is the best sub I've heard.

Yeah thats right. This is the best sub out there. Fans of Cannibal Corpse, Behemoth,Suffocatiion,Immolation,Marduk or any extreme metal this is the only choice. Yeah, and any rap hip hop fans want to go one on one I'll double bass you'll out . I can't stand that boom boom boom.

I have two 13w7's and a 1000/ I have an HD amp running two components Morels. I mighthave another 1000/ the end of 09.

I don't need all the rims or the flashy chains. I assure you''ll will hear me coming. So, all you posers SUFFER!

Wow wat power capitietes this is a great plat form for a great sound system

Just upgraded from a w6 whoa talk about a difference this sub will literally
blow you away. I havent got its potential all the way since I have just a
500/1 jl audio amp but just with this amp not even turned all the way up I
mean dang the bass it sounds so good. Saving up for a 1000/1 I can just
imagine the bass what it is going to be.

I have four of these in my Honda Civic(no back seats). I have now sustained hearing damage and can only hear about 10% of what I used to. But with all the bass these bad boys pound out, there is no need for good hearing. I have received 47 sound violations so far, but it is well worth it.

I had one of these subs in my 05 frontier ext cab in a 3.5 cu ft net, slot ported enclosure, and it loved anything you played and actually flexed the winshield in the truck with the jl 1000/1 in there. It is a very very good sub, however it is not the end all be all sub, there are other non-mainstream subs out there that have the same clarity more rms, etc. etc.

A good sub to go with for install that isn't really complicated, and if you want the wow factor....It will take 1500 watts of clean power in the enclosure above, and get stupid loud if thats what you want though. Be sure to use a quality amp and set your gains on the amp with a multimeter or oscilloscope.




the best of the best!

Written by: cubanito1133 from Downey, CA on October 31, 2007

this is the best sub ever created! it has such an amazing sound, and it gets as low as you want with absolutely NO distortion! it is a lil' pricey, but worth the money! it needs some room to breathe, so be sure to give a good, roomy home (sealed box w/ slotted port). it will definetly please the bass junkie and will knock pictures off the walls in your house when you pull up in the driveway!! be sure to give it plenty of power (personal recommendation is a JL Audio 1000/1), and adjust accordingly to your taste. i like the loud, boomy bass that other drivers hear and feel when you pass them by, but it can pretty much do what you ask it to. JL Audio has never let me down, so i highly recommend this sub, and ALL JL products!

Enclosure Compatibility


W-Cone: The JL Audio W7 subwoofer utilizes a W-Cone design, a unit-body cone assembly, that delivers astonishing cone stiffness with minimal mass. The shape also provides incredible torsional rigidity, which is critical to maintaining voice coil alignment at the suspension limits. In order to gain maximum stiffness, two lightweight mineral-filled polypropylene skins are bonded together at the perimeter and the center of the assembly. The lower skin's cross-section is shaped like a "W", and provides incredible rigidity when bonded to the dished upper skin.

OverRoll Surround: OverRoll Surround technology allows JL Audio to make full use of the entire footprint of the speaker, placing the surround further to the outside than in a conventional woofer. This means that W7 subwoofer can use a large roll for all its benefits without sacrificing cone area. By maximizing the effective piston/total footprint ratio, the W7 subwoofer can deliver more output for a given excursion and outside frame diameter. This means that the prodigious excursion advantage of the W7 can be put to full use enhancing output, rather than making up for lost piston area. This technology also provides a geometry advantage on the outside edge of the surround roll, allowing for more linear operation. A further benefit is that the mounting holes are inherently sealed by the surround, resulting in an improved box seal.

Dual Voice Coil: Due to the 13W7's dual 1.5 ohm coils, there is greater amplifier application flexibility. The speaker may be configured as a 0.75-ohm woofer (coils in parallel), a 3 ohm woofer (coils in series), or it can be driven by two amplifiers, each driving one 1.5 ohm voice coil).

Ultra-Long Voice Coil: The W7 subwoofer features an ultra-long voice coil to allow extreme linear excursion, phenomenal power handling and control. The massive surface area of these coils is excellent for heat dissipation, while the huge winding height provides the necessary motivational force to achieve the huge excursion of the W7 designs. Considering their size, the W7 voice coils are extremely light in weight. The W7 uses aluminum-alloy wire (instead of conventional copper) and a specific winding method to achieve JL Audio's desired electrical properties. The light weight of the coils helps keep the overall moving mass down at manageable levels, which is extremely important for efficiency and sound quality reasons.

Floating Cone Attachment Method (FCAM): JL Audio's patented FCAM technology is an innovative method of bonding the surround/cone assembly to the voice coil/spider assembly. This assembly technique ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.

Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method aimed at improving dynamic motor behavior. As a result of DMA optimization, W7 motors remain linear in motor force over a very long range of excursion, and also maintain a highly stable fixed magnetic field in the gap over a wide power range. The result is vastly reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.

Massive Forced Air Cooled: The elevated frame design of the W7 delivers cool air through slots directly above the top-plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.

Radial Cross-Drilled Pole Piece: This innovative venting system greatly enhances thermal dissipation and power handling by directing air flow onto the voice coil former and works in conjunction with the Elevated Frame cooling technology to effectively remove heat from the voice coil. This improves power handling and reduces power compression effects, leading to more linear performance.

Progressive-Roll Spider: The large, progressive-roll spider provides precise control and motor/voice coil alignment without limiting excursion prematurely.

Plateau-Reinforced Spider Attachment: The lower reinforcement collar, attached to the voice coil former of the W7, incorporates a plateau design dedicated to relieving material stress and providing a solid attachment surface for the inner edge of the spider.  The plateau of the reinforcement collar provides excellent contact area for adhesive therefore creating an incredibly strong bond at a critical point within the driver.

Co-Extruded Double Lead Wires: The extruded casing and carefully engineered attachments ensure controlled lead-wire behavior under the most extreme excursion demands. Two conductors are used per connection for ample current carrying capability.
