Application #6 - Subwoofer Cardioid Mode - Three Subwoofers 

 
For  applications  where  multiple  subwoofers  are  required  but  are  located  close  to  the  performers,  CVXL  subwoofers 
feature a cardioid mode setting which helps to reduce subwoofer levels behind the stage side while still achieving good 
audience coverage.  The diagram and tables below show how to connect three CVXL-118s/CVXL-218s subwoofers using 
cardioid mode.
