Description: 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.

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
Summary:
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!
Detailed Information:
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).
