5.2 When & where to use Configurable Directivity flanges
The diagrams show audience area coverage for a stereo system. While the GEO cluster will deliver even
SPL from the front to the rear of this audience area, there are “holes” near the front in the centre and at
the outside edges. We cannot fill the outside coverage gaps without enlarging the centre gap, and vice
versa (left figure below).
If 120° Configurable Directivity Devices are installed at the bottom cabinet of the clusters, coverage will
look more like the pattern in right figure below.
- 6dB coverage, all GEO M10 in 80° configuration -6dB coverage, bottom GEO M10 in 120° configuration
In curved vertical arrays, the 120° Configurable Directivity Device can be used:

On the bottom row of curved vertical arrays, to fill in coverage gaps in the front rows.

On all rows of curved vertical arrays, in cases where 120° of horizontal coverage is preferred
to 80°.
IMPORTANT
Installing or removing one of the two flanges anticipating asymmetrical coverage will
degrade both coverage and frequency response.
