JL Audio 12W1v3-2 12″ 300 Watt 2 Ohm Subwoofer (12W1v3-2)
The 12W1v3 is a lightweight 12-inch driver
with excellent performance capabilities at moderate power levels. It
features moderate mounting depth with no pole-vent, so the rear of the
motor structure can be placed directly against an enclosure boundary.
Excellent excursion capability and linearity allow it to reproduce
sub-bass with shocking extension and quality. Several of JL Audio’s
proprietary technologies enhance its performance and reliability.
The 12W1v3-2 is best used with amplifier power in the 75W – 300W range
and is optimized to operate in a compact 1.10 cu. ft. (31.5 l) sealed
Dynamic Motor Analysis – DMA Optimized Motor
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.
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
15W3v3 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.
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 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
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
The payoff is reduced distortion, improved transient performance and stellar sound quality.
