JL Audio 8W7AE 8-inch Subwoofer Driver

Words like "extreme," "reference" and "ultimate" get thrown around quite a bit in the subwoofer driver world, but rare is the product that can honestly lay claim to them. Taking the W7 design formula to its highest level, the 13W7AE offers a staggering linear excursion envelope that exceeds 1. Our most potent subwoofer driver is best used with amplifier power in the W - W range and is optimized to operate in a 1.

Detailed enclosure recommendations can be found in the "Specifications" tab. Functionally, they are identical to the original W7's, but are they distinguished by the following cosmetic differences:. Summary: JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients This research is aimed at decoding what we refer to as the "Loudspeaker Genome" Starting with the 15W3 and the W7 Subwoofers in the late 's and early 's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.

DMA is a Finite Element Analysis FEA -based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, "big-picture" solution. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed.

These modeling routines are intense, requiring hours to run for a whole speaker. DMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the "fixed" magnetic field.

This delivers intensely valuable information compared to traditional modeling, which assumes that the "fixed" field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this "fixed" field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability.

Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:.

Our ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems. The payoff is reduced distortion, improved transient performance and stellar sound quality.

W-Cone U. Patent 6,, Summary: The W-Cone is a unit-body cone assembly that delivers astonishing cone stiffness with minimal mass.

The shape also provides superb torsional rigidity, which is critical to maintaining voice coil alignment at the suspension limits. Detailed Information: The more excursion and motor force a speaker has, the more important cone rigidity becomes.

The acceleration forces are extreme, requiring the cone to withstand rapid changes in speed and direction without deformation. Deformation not only leads to distortion, but can also affect the speaker's mechanical integrity by allowing the voice coil to go out of alignment and rub on the top-plate and the pole-piece of the motor.

There are several approaches to enhancing cone rigidity. The use of these exotic materials is typically accompanied by marketing claims that the material chosen has exceptional stiffness-to-mass characteristics.

These are true statements, but can be misleading. While these materials have excellent stiffness-to-mass properties compared to paper or poly , they are not lighter than paper or poly in practice.

This means that their use accepts the compromise of added moving mass on the design. This leads to efficiency penalties and suspension complications it's harder to keep a heavy mass aligned properly. A simple poly cone diaphragm, while sufficient for lower power designs, would not remain rigid under the demands that the W7 design requires. Our engineering team knew that high levels of cone rigidity would be needed, but they focused on achieving rigidity without a huge weight penalty.

This ultimately led to the design we call the W-Cone. The W-Cone assembly achieves its rigidity through architectural means, rather than through inherently stiff materials.

The design addresses the stiffness issue by using two lightweight mineral-filled polypropylene skins, bonded together at the perimeter and the center of the assembly. The lower skin's cross-section is shaped like a 'W', hence the name, and provides incredible rigidity when bonded to the dished upper skin.

The effect is not unlike the trusses of a bridge or the unit-body construction of a modern automobile. In addition to the overall rigidity benefit, the lower skin's shape distributes the force generated by the coil and motor more evenly than a typical diaphragm. The force is not only applied to the apex but also distributed to the perimeter of the outer diaphragm for more linear behavior.

A further benefit of the W-Cone is that the upper skin the one in contact with the listening environment , is isolated from the high air-pressure gradients of the enclosure, further reducing deformation and distortion. If analyzed in terms of weight per square inch of piston area, the W7 cone-body weighs 1. So why polypropylene? As stated above, our patented W-Cone technology achieves all of the benefits of more exotic materials while better suiting the unique nature of the W7.

Since the W7 surround is detachable, the moving system including the diaphragm is subject to mechanical stress unseen in conventional designs. Because the user can tug on the cone while manipulating the surround, the cone must be able to handle this without buckling or deforming.

Paper, metal or brittle composite cones would not handle this well. Our two-skin unit-body cone design achieves outstanding axial and torsional stiffness to withstand all kinds of abuse, and will remain largely unaffected and unblemished. Elevated Frame Cooling U. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression. Detailed Information: Many speakers employ venting techniques to enhance voice coil cooling.

This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. While it provides a modest cooling benefit, this low-velocity air-flow does not blow directly or strongly on the voice coil.

Our patented design improves upon this cooling technique in a number of ways. By elevating the frame above the top-plate of the motor via stand-offs integrated into the bottom of the frame a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate.

This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly. Another important benefit is that the upper surface of the top-plate one of the speaker's hottest parts is directly exposed to cooling air flow, whereas on a conventional design it is isolated from the air flow by the lower flange of the frame. The elevated frame technology greatly increases thermal power handling, reduces compression effects and does so without any additional parts.

Patent 6,, Summary: This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.

This feature helps ensure concentricity of the surround, spider and voice coil without torquing the suspension to achieve it. This allows for the inevitable, slight variations in production part dimensions without having them negatively impact the integrity of the suspension and coil-centering at high excursions. Detailed Information: One of the first things you notice about a W7 is that something is "missing" Of course, this is actually not the case.

The mounting flange is simply hidden beneath the surround and is made accessible for mounting purposes by detaching the outer edge of the surround and moving the roll to the inside a pretty neat little trick. Apart from the obvious benefits of amazing your friends as you pull the surround off your speaker, there is a serious technical issue that led us in this design direction: Effective Piston Area "Sd".

This is essentially the speaker's "cylinder bore", to use an automotive engine analogy, and is calculated by measuring the diameter of the diaphragm including one-half of the surround roll-width. In other words, from the top-center of the surround on one side to top-center of the surround on the other side. The displacement capability of a speaker is determined by this piston area times the speaker's excursion capability.

Displacement of air is directly linked to output potential. Therefore, the more air a speaker can ultimately displace, the louder it can play. That being said, there is a big difference between piston area and excursion: piston area doesn't need power to make it happen.

This means that by making a larger piston, you are directly improving displacement for a given amount of excursion and, therefore, making your speaker more efficient. This is not the only factor that governs efficiency, but it is a major one.

To make a speaker have more excursion capability not only requires a motor design that can deliver more stroke, but also requires a surround rugged enough to handle the demands of longer excursions and controlled enough to keep everything lined up properly. If the surround's roll-width is not adequately large, its behavior compliance is not linear over the useful stroke of the woofer and it is more likely to fatigue and fail.

For this reason, speakers with longer excursion capability generally need larger surround rolls we won't comment on the ones that use large rolls strictly for cosmetic effect. The problem with big surrounds is that they begin to encroach on the effective piston area of the driver.

For example, a typical inch woofer with a medium-sized roll has an effective piston area of Compare this to a fat-surround inch woofer which has a piston area of To overcome this loss, the fat-surround woofer has to produce more excursion to displace the same air as the woofer with the medium surround and will require more power to do so.

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. The 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.

Patent 6,, Summary: This innovative venting system greatly enhances thermal dissipation and power handling by directing air flow onto the voice coil former, working 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. Detailed Information: This technology differs from a conventionally vented pole-piece in that the air flow is capped off at the top of the pole-piece and directed through machined holes on the outer wall of the pole-piece to the region directly behind the voice coil.

The top portion of the pole-piece is smaller in outside diameter where the holes vent and helps create a high-volume, high-velocity airflow path between the inner-coil cavity and the ambient air of the enclosure.

This helps remove super-heated air that is trapped between the coil former and pole-piece on a conventional design, leading to a dramatic improvement in cooling efficiency, especially at high excursions.

Engineered Lead-Wire System U. Patent 7,, Summary: Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands. Detailed Information: Managing the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design.

To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider rear suspension of the driver. The biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance.

Lead-wires that are attached or woven into the spider material can alter the spider's "stretching" behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits.

As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs. While a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer.
