Features

Dual Voice Coils: Due to the 12W6v3-D4's dual 4 ohm voice coils, the subwoofer can be configured as a 2-ohm (voice coils wired in parallel) or 8-ohm (voice coils wired in series) driver. The included jumper wires allow easy adjustment from one configuration to the other (the factory jumper position is 2-ohm).

Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method of improving dynamic motor behavior. As a result of DMA optimization, the 12W6v3-D4 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 bass.

Pole-Vent Airflow Control (PVAC): The bullet-shaped structure inside the pole-vent directs airflow and increases air velocity to effectively reduce voice coil temperature, leading to improved fidelity and reliability.

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.

Elevated Frame Cooling System: The elevated frame design of the 12W6v3-D4 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 has 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 mesh grille insert specifically designed to fit into the inner diameter of the trim ring (item number 136SGR126, sold separately).

Engineered Lead Wire System: JL Audio's engineered flying lead-wires have carefully engineered entry and exit support structures molded into the terminals and the voice coil collar and are jacketed to further reduce the likelihood of shorting and fatigue. The result is predictable high-excursion lead-wire behavior with long term reliability, and none of the compromises inherent to a woven-in lead wire system (when attached or woven into the spider material, lead-wires can alter the spider's motion, leading to asymmetrical spider behavior).

Enclosure Compatibility

Sealed Enclosure: JL Audio recommends a sealed box size of 1.105 ft³ (1.0 ft³ net, plus the sub's 0.105 ft³ displacement). A diagram is provided in the owner's manual for a sealed box with external dimensions of 15" W x 15" H x 12" D, assuming 3/4" thick material. (If you are using 5/8" thick materials, subtract 1/4" from each dimension.)

Ported Enclosure: The ported box size JL Audio recommends is 1.405 ft³ (1.3 ft³ net, plus the sub's 0.105 ft³ displacement). The recommended slot port is 12-1/2" x 1-1/2" x 31-5/8", resulting in a tuning frequency of 33 Hz and a -3dB point of 31 Hz.
