Good coverage of audiences often is a conflicting combination of:
*wide coverage for the closest audience (short throw)
*narrow coverage for distant areas (long throw)
The asymmetrical dispersion horn coverage varies from "short throw" to "long throw"
along the vertical axis (keeping a constant vertical directivity). In conclusion,
directivity feature of (50º to 100º(H), 55º(V)) can be seen as if the horn itself had
"two" horizontal directivities (audience coverage), which depend on the distance. For
short distances the horn should be used with its "wide" dispersion (100º). For long
distances the horn should be used with its "narrow" dispersion (50º). We suggest
you to pay attention to the following examples.
3.2.1. Vertical-Positioned Cabinets (Flown and aiming to the audience)
We need wide
coverage (100º)
for the closest
listeners
and
narrow
coverage for the
distant
audience.
