MECHANICAL AND ACOUSTICAL FEATURES

DIMENSIONS

The OPERA UNICA series has been designed with the intent to optimise weight and dimensions.
The cabinet is light but resistant, and features 2 handles, one on the side or one at the top, for easy handling.
For a quick comparison of the 2 models, the overall dimensions are the following:
OPERA UNICA 12 - 350 mm (L), 642 mm (H), 349 mm (D)
OPERA UNICA 15 - 420 mm (L), 722 mm (H), 419 mm (D)

SOUND COVERAGE

The special design of the horn, shown in the figure, is
common for all 2 models.
In horizontal, the coverage is differentiated between the
value of 85° (upper part) and 120° (lower part).
This is to optimise sound emission, for example during
vertical installation in reverberant environments.
The overall vertical opening (85°) is asymmetrical, to increase
the horn sound pressure for long distance.
In case of use with monitoring function or in case of
horizontal positioning (wall-mounted) of the speaker, take
these data into account so as to calculate the correct coverage
of the environment.
