Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.

Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method aimed at
improving dynamic motor behavior. As a result of DMA optimization, W3v3 motors
remain linear in motor force over a very long range of excursion, and also
maintain a highly stable fixed magnetic field in the gap over a wide power
range. The result is vastly reduced distortion, faithfully reproduced
transients, and tight, clean, articulate bass.
Floating Cone Attachment Method (FCAM): JL Audio's patented FCAM technology
is an innovative method of bonding the surround/cone assembly to the voice
coil/spider assembly. This assembly technique ensures proper surround geometry
in the assembled speaker for better excursion control and dynamic voice coil
alignment.
Vented Reinforcement Collar (VRC): The Vented Reinforcement Collar is
a composite structure that addresses two issues related to reliability. By
reinforcing the critical junction between the cone, voice coil and spider, the
VRC greatly reduces failures due to glue breakdown or material weaknesses. It
does this by greatly increasing adhesive contact area and providing stress
relief to the spider material at excursion extremes. the VRC also feature slots
that facilitate air flow directly onto the voice coil windings to reduce thermal
compression effects and enhances reliability.
Spider/Lead Wire Assembly: The W3v3 features a unique spider, coil and
terminal subassembly which is assembled prior to installation in the speaker
frame for optimum alignment and glue-joint integrity. The spider is
insert-molded into a composite carrier tray which also incorporates the terminal
assembly and lead wire strain relief features for enhanced reliability and
optimal alignment of parts. The flying lead wires are carefully controlled and
strain-relieved without resorting to woven-in lead wires, which can degrade
spider performance.
Elevated Frame Cooling: The elevated frame design of the W3v3 delivers
high-velocity air flow through slots directly above the top plate to the voice
coil of the speaker. This not only enhances power handling, but also sound
quality by minimizing dynamic parameter shifts and power compression.
Surround Stress Relief: By creating a radiused feature on the edge of
the cone, stress is relieved from the surround material at maximum forward
excursion, resulting in longer life and more consistent surround behavior.
Customizable Trim Ring: The woofer comes with a removable ring made of
black ABS plastic which can be painted to match the installation theme and
create a personalized look. You can purchase optional grille mesh inserts which
are specifically designed to fit into the inner diameter of the trim ring.

Recommended Sealed Box Volume: The sealed box size recommended by JL
Audio is 0.625 cu/ft. A diagram is provided in the owner's manual for a sealed
box with external dimensions of 18" W x 11" H x 9" D, assuming 3/4" thick
material. (If you are using 5/8" thick materials, you should subtract 1/4" from
each dimension.)
Recommended Ported Box Volume: The ported box size
recommended by JL Audio is 1.125 cu/ft. A diagram is provided in the owner's manual for a sealed box
with external dimensions of 23" W x 12" H x 13.125" D, assuming 3/4" thick
material. (If you are using 5/8" thick materials, you should subtract 1/4" from
each dimension.) A slot port is recommended with the following dimensions:
- Slot Width = 1.25"
- Slot Height = 10.5"
- Slot Length = 28.125" (a right angled port with a 15.5" extension)
