Features

Woofer: The JL Audio W1v3-4 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, W1v3-4 motors remain linear over a long excursion range, and also maintain a highly stable fixed magnetic field in the gap over a wide power range. The result is 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 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 W1v3-4 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 W1v3-4 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 an optional grille mesh insert specifically designed to fit into the inner diameter of the trim ring (item number 136SGR1031, sold separately).

Enclosure Compatibility

Sealed Enclosure: JL Audio recommends an optimum sealed enclosure volume for the 10W1v3-4 of 0.587 ft³ (0.55 ft³ net, plus the sub's 0.037 ft³ displacement), resulting in a -3dB point of 43.1 Hz.

Ported Enclosure: JL Audio recommends an optimum ported enclosure volume for the 10W1v3-2 of 0.937 ft³ (0.9 ft³ net, plus the sub's 0.037 ft³ displacement). The recommended slot port is 1-1/8" (wide) x 10" (tall) x 29-3/4" (long), resulting in a tuning frequency of 32.17 Hz and a -3dB point of 31.92 Hz.
