MECHANICAL AND ACOUSTICAL FEATURES
DIMENSIONS
SOUND COVERAGE
The OPERA series has been designed with the intent to optimise weight and dimensions.
The cabinet is lighter but more resistant, and features 2 handles, one on the side and one at the top, for easy
handling.
For a quick comparison of the 3 models, the overall dimensions are the following:
OPERA10 - 300 mm (L), 552 mm (H), 301 mm (W)
OPERA12 - 349 mm (L), 642 mm (H), 350 mm (W)
OPERA15 - 420 mm (L), 772 mm (AH), 419 mm (W)
The special design of the horn, shown in the gure, is
common for all 3 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 special design of the horn, shown in the gure, is
common to the 3 models. The overall vertical opening (85°) is
asymmetrical, to increase the sound pressure of the horn at
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.
