Woofer: The JL Audio W1v3-2 subwoofer features an
injection-molded, mica-filled polypropylene cone with an embossed metallic
JL Audio logo and a rubber surround for added durability, woofer excursion
and bass response.
Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary
method of improving dynamic motor behavior. As a result of DMA optimization, the
W1v3-2 motor remains linear over a long excursion range, and also maintains a
stable, fixed magnetic field in the gap over a wide power range. The result is
reduced distortion, faithfully reproduced transients, and tight, clean, articulate
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
reduces failures due to glue breakdown or material weakness. It
does this by 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, thus
reducing thermal compression effects and enhancing reliability.
Insert Molded Suspension/Coil/Terminal Sub-Assembly: The
W1v3-2 features a unique spider, coil and terminal subassembly, 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/spider alignment.
Elevated Frame Cooling System: The elevated frame design of
the W1v3-2 delivers cool air through slots directly above the top-plate to the
voice coil. 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 an optional grille mesh insert
specifically designed to fit into the inner diameter of the trim ring (item number
136SGR1231, sold separately).
Sealed Enclosure: JL Audio recommends an optimum sealed
enclosure volume for the 12W1v3-2 of 1.152 ft³ (1.1 ft³ net, plus the sub's
0.052 ft³ displacement), resulting in a -3dB point of 38.99 Hz.
Ported Enclosure: JL Audio recommends an optimum ported
enclosure volume for the 12W1v3-2 of 1.652 ft³ (1.6 ft³ net, plus the sub's
0.052 ft³ displacement). The recommended slot port is 1-1/2" (wide) x
14" (tall) x 30-3/4" (long), resulting in a tuning frequency of
31.79 Hz and a -3dB point of 31 Hz.
