Subwoofer cardioid array

Subwoofer cardioid array
The ETX-15SP and ETX-18SP subwoofers have cardioid array processing originally developed
for Electro-Voice concert subwoofer systems. Cardioid subwoofer arrays can be used to direct
the output of an array of subwoofers in order to limit excessive amounts of bass in undesired
areas. These arrays can be used to keep bass off of a stage, provides more consistent bass
coverage in the audience, and reduces bass in the surrounding area.
Multiple ETX-15SP or ETX-18SP can be arrayed to create a cardioid polar pattern. See
Cardioid pattern top view. The cardioid setting in the DSP menu is optimized to produce a
rear rejection of up to 30 dB without any additional processing. The rejection may be less in
smaller indoor environments than in larger outdoor environments. For best performance,
adhere to the following guidelines:

The subwoofers must all be the same model, for example all ETX-15SP or all ETX-18SP.

The subwoofers must be physically placed in one (1) of the options shown. See Cardioid
physical alignment.

Front firing subwoofers use the NORMAL location setting, and rear firing subwoofers use
the CARDIOID setting. All other settings should be the same between front and rear firing
subwoofers. For more information, see Subwoofer DSP control menu, page 32.

To add delay to the cardioid array, add the same amount to both the front and rear facing
subwoofers. For more information, see Subwoofer DSP control menu, page 32.
