subwoofer system. This product has been critically engineered to deliver
exceptional performance in your home theater or audio system for many years to
come.
As a company, we are intensely committed to core research into
high-performance loudspeaker and amplifier technologies. JL Audio's long-
excursion subwoofer driver designs are widely considered as reference
standards for linear behavior and high output. We have also focused our
efforts to create powerful amplifier and signal-processing technologies
specifically aimed at delivering exceptional low-frequency performance. Your
Dominion™ subwoofer combines these core disciplines within a compact,
beautifully crafted package to deliver an unparalleled listening experience.

IN DOMINION™ SUBWOOFERS
DMA-Optimized Motor System
DMA is JL Audio's proprietary Dynamic
Motor Analysis system aimed at
improving dynamic motor behavior. As a
result of DMA optimization, loudspeaker
motors remain linear in force over an
extreme range of excursion and also
maintain a highly stable fixed magnetic
field over a wide power range. This leads
to vastly reduced distortion and faithfully
reproduced transients... or put simply:
tight, clean, articulate bass.
VRC-Vented Reinforcement Collar
(U.S. Patent #6,118,884)
JL Audio's patented Vented Reinforcement
Collar improves the rigidity and stability
of the cone/spider/voice coil junction
and directs airflow over the voice
coil windings for improved thermal
performance.
Floating-Cone™ Attach Method
(U.S. Patent #6,501,844)
This assembly technique ensures proper
surround geometry in the assembled
speaker for better excursion control and
dynamic voice coil alignment.
Engineered Lead-Wire System
(U.S. Patent #7,356,157)
Carefully engineered lead-wire design and
attachments ensure controlled, quiet lead-
wire behavior under the most extreme
excursion demands, resulting in reduced
distortion, reduced mechanical noise and
improved reliability.
