Dual Voice Coils: Due to the 10W6v3-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
Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary
method of improving dynamic motor behavior. As a result of DMA optimization, the
10W6v3-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
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
Elevated Frame Cooling System: The elevated frame design of
the 10W6v3-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 136SGR106, 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).
Sealed Enclosure: JL Audio recommends a sealed box size of
0.628 ft³ (0.55 ft³ net, plus the sub's 0.078 ft³ displacement). A diagram is
provided in the owner's manual for a sealed box with external dimensions of
12-1/2" W x 12-1/2" H x 10-1/2" 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
0.828 ft³ (0.75 ft³ net, plus the sub's 0.078 ft³ displacement). The recommended
slot port is 10-7/8" x 1-3/8" x 27-5/8", resulting in a tuning
frequency of 39 Hz and a -3dB point of 33 Hz.
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 verify what’s in the box, 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.
