Cardioid subwoofer arrays
By using a cardioid configuration, the output of multiple X12i-128 subwoofers can be directed
toward the audience while at the same reducing the low-frequency energy behind the array.
These arrays can be used to keep bass off of a stage, provide more consistent bass coverage
in the audience, or reduce bass in the surrounding area.
A cardioid deployment requires at least two X12i-128 subwoofers. Electro-Voice provides
optimized DSP speaker settings for the X12i-128 in cardioid configurations. These settings can
be implemented in hardware controlled by SONICUE or IRIS-Net software. In addition, you can
model the acoustical output of cardioid arrays in

The rejection may be less in smaller indoor environments than in larger outdoor environments.
The subwoofers must be physically placed in one of the options shown.
