6.1. The CARDIOID preset
The X18WE can generate an uncompromised cardioid behaviour, which means that
there is no need for special cabinets, enabling the use of the system's full efficiency
with just "one finger".
In its minimum configuration a Cardioid setup consists of a stack of three subwoofer
cabinets.
Only one subwoofer is needed to compensate for the energy of the other two radiating
to the front. Then, the cabinet facing to the back (to the stage) should be located in the
centre of the column.
Fig.11. Cardioid configuration for X18WE subwoofer
The front facing subwoofers must be driven with [LPF90+3] or [LPF90+6] preset
and the back facing subwoofer must be driven with [CARDIOID] preset.
