SW221 CARDIOID OPERATION

SW-221 subwoofer can be configured in cardioid arrays to reduce the amount of output heard behind the subwoofers. Subwoofer cardioid arrays are archived by placing three units coplanar to each other with one unit facing the opposite direction. The output of the reversed subwoofer cancels the output of the other subwoofers normally present behind the units.
Tecnare has specifically designed cardioid presets (SW221_60i and SW221_75i). However, we recommend calculating the appropriate ratio of forward to rear facing
loudspeakers, as well as the measurement of required parameter setting of polarity, delay, and
gain. For more information, contact Tecnare Technical Support.
