APPLICATION INFORMATION
The ZR800-CW is a powerful 8-inch
component woofer designed to operate
in automotive sound systems reproducing
the frequency range between 30 Hz
and 400 Hz. It can be used in infinite-
baffle or enclosed applications as an
extremely potent, dedicated mid-
bass speaker or as a full woofer.
Active Filtering is Recommended:
When used as a mid-bass speaker, we
recommend the use of dedicated amplifier
channels and active filtering (electronic
crossovers) with the ZR800-CW.
The ZR800-CW maintains smooth frequency
response characteristics up to 500 Hz, so it
is advisable to cross it over with mid-range
speakers at 300-400 Hz to ensure a smooth
transition. Pushing it higher than this range
may result in uneven response which may
require equalization to correct.
Infinite Baffle:
As a dedicated mid-bass speaker operating
above 50 Hz (with active filtering) the
ZR800-CW can be safely operated at
power levels momentarily exceeding 200
watts per woofer. When operating below
50 Hz as a true woofer, 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 sealed
or ported enclosures as recommended
in this manual. Again, power should be
limited to no more than 125 watts per
woofer if being played below 50 Hz.
More power can be used if appropriate
active high-pass filtering is applied.
