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.
Overview: The JL Audio ZR800-CW is a powerful 8-inch component woofer
designed to operate in automotive sound systems reproducing the frequency range
between 30Hz and 400Hz. It can be used in infinite-baffle or enclosed
applications as a dedicated mid-bass speaker or as a subwoofer.
Polypropylene Cone: The cone and suspension elements were designed and
manufactured by the world-famous Dr. Kurt Müller & Co of Germany. The speaker
features a low-mass, mineral-filled polypropylene cone woofer with a santoprene
surround. The cone and surround are inherently well damped to deliver an
uncolored, neutral midbass without any coloration. The woofer is also equipped
with a progressive roll spider.
DMA-Optimized Motor System: Within the DMA (Dynamic Motor Analysis)
optimized motor structure, the CNC-machined back plate, pole piece, and top
plate elements offer a degree of precision not possible with conventional forged
or stamped parts. The ultra-thin gauge voice coil (1.75") is treated with
proprietary, high-temperature adhesives and wound on an aluminum former to
further improve thermal transfer, reliability, and linearity at high power
Cast Alloy Basket: The ZR800-CW features a proprietary cast alloy
woofer basket, designed to provide maximum rear open area while also
incorporating JL Audio's patented "Elevated Frame" cooling system. This cooling
technology, also found on W7 and W6v2 subwoofers, allows air to flow directly
across the top plate and onto the voice coil windings to greatly improve
linearity at all listening levels.
Mounting Ring and Grille: The JL Audio ZR800-CW comes supplied with an
ABS mounting ring and metal mesh grille.
Infinite Baffle: The JL Audio ZR800-CW can be installed as a free-air
driver in a infinite baffle application. As a dedicated mid-bass speaker
operating above 50Hz (with active filtering), the ZR800-CW can be safely operate
at power levels momentarily exceeding 200 watts. When operating below 50Hz as a
subwoofer, power should be limited to no more than 125 watts per woofer in
infinite baffle applications.
Enclosed Operation: The ZR800-CW can also be used in a sealed or
ported enclosure. Power should be limited to no more than 125 watts if being
played below 50Hz. More power can be used if appropriate active high-pass
filtering is applied.
- Recommended Sealed Box Volume: JL Audio recommends
mounting this woofer in a sealed enclosure made out of 3/4" MDF with an
internal volume of 0.75 cu/ft.
- Recommended Ported Box Volume: JL Audio recommends a
ported enclosure made out of 3/4" MDF with an internal volume of 1.125 cu/ft
using a 2" diameter x 5" long port.
