2.2. Cardioid Operation
SW-218 subwoofer can be con
fi
gured 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 speci
fi
cally designed cardioid presets (SW218EB_i, SW218_80i and SW218_70i). 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.
