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 infinitebaffle or enclosed applications as an extremely potent, dedicated midbass 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.
