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.

Features
Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary
method aimed at improving dynamic motor behavior. As a result of DMA optimization,
12W0v3-4 motors display linear force over a long excursion range, and also maintain
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
12W0v3-4 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 a rear gasket to provide an optimal
seal when installing into the enclosure.
Long Excursion: The 12W0v3-4 subwoofer has 11.4mm of linear
excursion, giving you louder bass with less distortion.

Recommended Sealed Box Volume: JL Audio recommends a 1.375
ft³ sealed box. 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 each dimension.)
Recommended Ported Box Volume: JL Audio recommends a 1.75
ft³ ported box. A diagram is provided in the owner's manual for a sealed box
with external dimensions of 17.5" W x 14.75" H x 16.25" D,
assuming 3/4" thick material. (If you are using 5/8" thick materials,
you should subtract 1/4" from each dimension.) A round port with a diameter
of 3" and a length of 14" is recommended, resulting in a tuning frequency
of 26 Hz and a -3 dB point of 30.8 Hz.
