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.
Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method aimed at
improving dynamic motor behavior. As a result of DMA optimization, W0v2 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.
Elevated Frame Cooling: The elevated frame design of the W0v2 delivers
high-velocity air flow 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.
Rear Gasket: The woofer has a rear gasket which provides an optimal seal when installing into the enclosure.
Long Excursion: The 12W0v2 subwoofer has 11.4mm of linear excursion, giving you louder bass with less distortion.
Recommended Sealed Box Volume: The sealed box size recommended by JL
Audio is 1.375 cu/ft. A diagram is provided in the owner's manual for a sealed
box with external dimensions of 16" W x 19" H x 11.75" D, assuming 3/4" thick
material. (If you are using 5/8" thick materials, you should subtract 1/4" from
Recommended Ported Box Volume: The ported 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 17.5" W x 15.5" H x 15.5" D, assuming 3/4"
thick material. (If you are using 5/8" thick materials, you should subtract 1/4"
from each dimension.) The box should be tuned to 26 Hz. A rounded port with a
diameter of 3" and a length of 14" is recommended.
