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.

Features
Woofer: JL Audio W1v2
subwoofer features an
injection-molded, metallic-finish polypropylene cone woofer with an embossed
metallic JL Audio logo with a rubber surround for added durability, woofer
excursion and bass response.
Surround Stress Relief: By creating a radius 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
Interlocking Cone & Dust Cap: The W1v2's utilize a dust cap that is
not just glued, but also interlocks with features molded into the cone body for
a tight snap-fit. This creates a more rigid cone assembly and a more reliable
dust cap attachment.
Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method aimed at
improving dynamic motor behavior. As a result of DMA optimization, W1v2 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: The Vented Reinforcement Collar (VRC) is
a composite structure that addresses two issues related to reliability.
- Stress Relief: By reinforcing the critical junction between the
cone, voice coil and spider, the VRC greatly reduces failures due to glue
breakdown or material weakness. It does this by greatly increasing adhesive
contact area and providing stress relief to the spider material at excursion
extremes
- Air Flow: The VRC also features slots that facilitate air flow
directly onto the voice coil windings. This reduces thermal compression
effects and enhances reliability
Insert Molded Suspension/Coil/Terminal Sub-Assembly: The W1v2 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. This type of assembly ensures precise lead wire length, lead wire
entry and exit angles; and coil to spider perpendicularity.
Elevated Frame Cooling System: The elevated frame design of the W1v2
delivers cool air 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.
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 1.75 cu/ft. A diagram is provided in the owner's manual for a sealed
box with external dimensions of 18.5" W x 16.5" H x 13.75" 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 2.625 cu/ft. A diagram is provided in the owner's manual for a sealed box
with external dimensions of 23.75" W x 17" H x 18" 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 =1.5"
- Slot Height = 15.5"
- Slot Length = 31.5" (a right angled port with a
13.5" extension)
