GRAND CALLAS

Floorstanding Speaker

With the new Callas Series, Opera wants to transfer the pleasure of listening to music inside the domestic walls recreating a three-dimensional sound stage, focused and stable, with the correct timbre, dynamic, detail and absence of listening fatigue. To achieve this, each element of the project has been subjected to careful listening tests.
