The cardioid conguration consists in reversing 1 element in an array of 4 subwoofers.
Refer to the subwoofer owner's manual and to the
Cardioid congurations
technical bulletin.
Grouping subwoofers
Place the subwoofer enclosures side by side. If not possible, the maximum distance between two adjacent
acoustic centers must be 2.8 m or 1.7 m if the upper frequency limit of the subwoofer system is at 60 Hz or
100 Hz, respectively.
Delay values
Do not forget to add the pre-alignment and geometric delays depending on the conguration.
