JL Audio 10W3v3-2 10" Subwoofer Driver - 10W3V32
W3v3 Subwoofer Drivers
Clearly the best sounding W3's yet, these subwoofers feature DMA-optimized, long linear excursion capability to minimize distortion and increase output. W3v3's are available in single 2 ohm, 4 ohm and 8 ohm versions and are superb performers at medium power levels in compact sealed or ported enclosures.
Multiple patented technologies enhance performance and reliability. As with JL Audio’s flagship drivers, development was guided by JL Audio’s proprietary DMA (Dynamic Motor Analysis) modeling system to deliver outstanding dynamic stability and low-distortion operation within their intended power envelope.
A mineral-filled polypropylene upper cone body with a metallic JL Audio logo medallion provides a classy new look, while a removable (and customizable) mounting flange trim ring receives grille-mesh inserts directly, without the need for additional grille hardware. (Grille mesh inserts are sold separately.)
DMA Optimized Motor System
DMA-optimized motor systems deliver highly consistent motor force over a long range of stroke and input power levels. This results in reduced distortion, enhanced detail resolution and superior dynamic balance, or more simply put, incredible bass!
For years, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors. This research is aimed at decoding what we refer to as the "Loudspeaker Genome"... in other words, to better understand the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Products like the 15W3, 18W3, W7, W6v2 and W1v2 subwoofers were all developed using DMA modeling, yielding vastly improved motor performance characteristics, compared to previous designs.
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 low-power DUMAX 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 between 20 and 35 hours to run for a whole speaker (it takes over one hour of computer processing time to run a single BL curve, generating 75-100 Megabytes of data).
DMA is able to analyze the real effects of 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. The reality is that this "fixed" field changes in reaction to the magnetic field created by current flowing through the voice coil. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor. Ignoring the dynamic nature of the "fixed" field, prevents specifically addressing the aspects of motor design that determine truly linear behavior, which are as follows:
- 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
The elevated frame design of the W3v3 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.
Many speakers employ spider 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.
Vented Reinforcement Collar
JL Audio’s patented 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.
The Vented Reinforcement Collar (VRC™) is a composite structure that addresses two issues related to reliability.
By reinforcing the critical junction betweeen 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.
VRC™ Technology is patented (U.S. Patent #5,734,734).
Floating Cone Attach Method (FCAM™)
JL Audio’s patented Floating Cone Attach Method (FCAM™) allows the cone and surround to be aligned independently of the spider/coil assembly, improving pistonic motion.
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.
Spider and Lead Wire Assembly
Nickel-plated brass push terminals combine with strain relief features to ensure solid contact and lead-wire reliability.
All new, hybrid-weave, progressive-roll flat spiders are preassembled, using a patent-pending process, onto a composite carrier to ensure optimum alignment of the suspension.
The W3v3's feature a unique spider, coil and terminal subassembly which is assembled prior to installation in the speaker frame for optimum alignment and glue-joint integrity.
The spider is insert-molded into a composite carrier tray which also incorporates the terminal assembly and lead wire strain relief features for enhanced relability and optimal alignment of parts.
By assembling these elements off the speaker frame, we are able to ensure better glue joints and superior alignment of parts.
The flying lead wires are carefully controlled and strain-relieved without resorting to woven-in lead wires, which can degrade spider performance.
One-piece nitrile-butylene rubber (NBR) surround and gasket design works in conjunction with a stress-relief feature molded onto the lower cone edge to improve reliability.
Injection-molded, mica-filled polypropylene lower cone bodies with integral bracing features permit shallow cone profiles without compromising rigidity.
By creating a radiused feature on the edge of the cone, stress is relieved from the surround material at maximum forward excursion, resulting in longer life and more consistent surround behavior.
Customizable Trim Ring
This removable ring can be painted to match the installation theme and is also designed as a receptacle for grille mesh inserts (sold separately).
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.
Additionally, you can purchase grille mesh inserts separately which are specifically designed to fit into the inner diameter of the trim ring. See your JL Audio dealer for details.
