FEATURES
WX Subwoofer Drivers

Built from the same DNA as the rest of the JL Audio subwoofer lineup and dedicated to the proposition that real value can only exist when real performance is delivered.

Like all JL Audio subwoofer drivers, the WX's are centered on a long excursion, DMA-optimized motor system, supported by our patented Elevated Frame Cooling and a highly linear suspension. This means they deliver lots of low-distortion, high-quality bass with all types of music. 

WX's are ideally suited for lower power applications and offer a powerful combination of performance, value and installation attributes.

You simply won’t believe you’re listening to our least expensive subwoofer drivers!

Great Bass in Small Enclosures

For maximum application flexibility, WX's are designed for use in compact sealed or medium-size ported enclosures.

DMA Optimized Motor System

Summary:

DMA is JL Audio's proprietary Dynamic Motor Analysis system and is aimed at improving dynamic motor behavior. As a result of DMA optimization, WX motors remain linear in motor force over a long range of excursion and also maintain a highly stable fixed magnetic field in the gap over a wide power range. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate 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 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 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 between 20 and 35 hours to run for a whole speaker.

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: 

1) Linear motor force over the speaker's operational excursion range

2) Consistent motor force with both positive and negative current through the coil

3) 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.
