Dynamic Motor Analysis (DMA): DMA is a JL Audio proprietary
method of improving dynamic motor behavior. As a result of DMA optimization,
the woofer's motor remains linear in motor force over a long excursion range,
and 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.
Elevated Frame Cooling: The elevated frame design of the
10WXv2 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.
Rear Gasket: The woofer has an integrated foam rear gasket
which provides an optimal seal when installing into the enclosure.
Sealed Box Volume: JL Audio recommends a 0.625 cubic foot
sealed box. A diagram is provided in the owner's manual for a sealed box with
external dimensions of 17-1/4" W x 11" H x 9" D, assuming 3/4"
thick material. (If using 5/8" thick materials, you should subtract 1/4"
from each dimension.)
Ported Box Volume: JL Audio recommends a 1.0 cubic foot ported
box. A diagram is provided in the owner's manual for a ported box with external
dimensions of 22" W x 12" H x 10-1/2" D, assuming 3/4" thick
material. (If using 5/8" thick materials, you should subtract 1/4" from
each dimension.) A single 3" diameter x 13-1/2" long port is recommended,
resulting in a tuning frequency of 35 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.
