Powerful, compact bass solutions for almost any vehicle!
W3v3 FlatWedge Low-Profile Ported System
A unique solution for tight spaces, integrating a highly capable W3v3 driver into a very low-profile, slot-ported design. Excellent sound quality and surprising output capability with moderate power.
Flared slot-port design minimizes turbulence and improves fidelity. Very low-profile enclosure design (less than 5-inches thick).

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 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.
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 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
