JL 10w3v3 home subwoofer

The JL driver is intended for car audio- witness it's 2 ohm VC impedance, which is commonplace in car systems, due to low driving voltage available, but not normally used in home audio systems.

To figure out box alignments on your own, you would need to use the T/S parameters and and a calculation program such as Unibox (runs in Excel, free) or one of the standalone programs for bass system calculation or a program like LspCAD which also does this type of calculation. There are recommendations for the box size at Crutchfield, for sealed and ported, but with no port recommendation; I'd take these with a grain of salt, as the automotive cabinet gain for low frequencies is quite different from what happens in a typical room- the ported cabinet recommendation of 1.25 cu ft is what I'd start at for a sealed alignment. You can get more complete T/S parameters at the JL audio site. Google is your friend...

Dynamic Motor Analysis - DMA Optimized Motor Summary:JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass. Detailed Information:Since 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the "Loudspeaker Genome"... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000'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. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil/cone position within the framework of a time-domain analysis. 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: Linear motor force over the speaker's operational excursion range Consistent motor force with both positive and negative current through the coil Consistent motor force at varying applied power levels 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. Elevated Frame Cooling Summary:JL Audio's Elevated Frame Cooling design 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. 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 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. Floating Cone Attach Method - FCAM™ 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. Detailed Information: JL Audio's patented FCAM™ technology is an innovative method of bonding the surround/cone assembly to the voice coil former/spider assembly. 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. Vented Reinforcement Collar Summary:JL Audio's Vented Reinforcement Collar (VRC™) improves the rigidity and stability of the cone/spider/voice coil junction and directs airflow over the voice coil windings for improved thermal performance. Detailed Information:The Vented Reinforcement Collar (VRC™) is a composite structure that addresses two issues related to reliability. By reinforcing the critical junction between the cone, voice coil and spider, the VRC greatly reduces failures due to glue breakdown or material weakness. It does this by greatly increasing adhesive contact area and providing stress relief to the spider material at excursion extremes. The VRC™ also features slots that facilitate air flow directly onto the voice coil windings. This reduces thermal compression effects and enhances reliability. Current versions of the VRC™ also incorporate lead-wire strain relief structures to improve mechanical reliability. Insert Molded Suspension / Coil / Terminal Sub-Assembly (U.S. Patent #7,379,558) Summary:Spiders, voice coils, terminals and lead wires are preassembled, using a patented process, onto a composite carrier for improved precision and reliability. Detailed Information:A conventional speaker is assembled in layers. In other words, multiple parts are assembled and glued sequentially into the basket, leading to stacking of tolerances and making it difficult to achieve optimal assembly precision. JL Audio's patent-pending insert-molded spider carrier permanently bonds the spider to a mechanically robust carrier that also incorporates the terminal assembly and lead wire strain relief features for enhanced reliability and optimal alignment of parts. This subassembly is assembled outside the speaker basket, for optimum alignment and glue-joint integrity. The benefit is a more precisely built, more mechanically sound loudspeaker. Customizable Trim Ring Summary:This removable ring can be painted to match the installation theme and directly receives JL Audio grille mesh inserts (sold separately). Detailed Information:This ABS trim ring is molded in black, but that doesn't mean it has to stay that way. By custom painting it, you can match your installation theme and create a personalized look. Specifically-designed grille mesh inserts are available separately and fit into the inner diameter of the trim ring. Helpful Tip: Installing the grille mesh inserts is much easier before mounting the woofer into the enclosure. Engineered Lead-Wire System (U.S. Patent #7,356,157) 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. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer. To overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.

Ok thanks. I finally found a way to run winisd on my mac computer. 1.25 cu ft for a sealed box works out great. I really like the look of the JL audio sub, that's why I would like to use it and I have seen some other diy'ers use it. I haven't bought the sub yet but they are available in 2,4, and 8 ohm. Thanks again

Great-

Did you use Parallels or VMWare, or do you have it setup with Bootcamp? I used to run Bootcamp all the time, but as I wanted to run WIN7 on late model hardware (Mac Pro and Macbook Pro Retina, which use USB3), the only easy way to support WIN7 was through virtualization- native bootcamp installation isn't possible unless you slip stream the Intel USB drivers into the WIN7 install. Good luck with your project, I figured 1-1/2 to 1-1/2 would be what you'd end up with. Don't forget subtract the driver volume when planning the enclosure size (don't use 1-1/4 gross, but 1-1/4 cu ft after the driver volume is taken out.

**kevinm** · 17 July 2014, 15:48 Thursday

And bracing volume! Don't forget to subtract that!

**Brak** · 17 July 2014, 18:59 Thursday

Sorry for the confusion, I actually found a site that has a java based version of win isd. linearteam.dk
It's a real pain I find running windows through a Mac so I found an easy alternative

**JonMarsh** · 17 July 2014, 19:29 Thursday

That's cool! There's a power circuit simulation program I use for work that's programmed in Java for that reason...
