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 to pay attention to the following examples.
3.6.1. Vertical-Positioned Cabinets (Hung and aiming to the audience)
We need wide coverage (100º) for the closest listeners and narrow coverage for
the distant audience.
