JL Audio ZR800-CW User Manual

JL AUDIO ZR800-CW                                                                                         3

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.
