The Callas Line stands at the absolute pinnacle of Opera Loudspeakers’ production, a benchmark for quality and sonic refinement.
Relaunched in 2014 after an extensive process of research and development, it includes three models – one bookshelf and two floorstanding speakers – unanimously recognized among the most acclaimed high-end loudspeakers worldwide.
With this series, Opera transforms the home environment into a true three-dimensional and focused stage, delivering extraordinary timbre, dynamics, and detail, together with a listening experience entirely free from fatigue.
This line is named after Maria Callas, the celebrated soprano of American origin who became Italian by choice, a great ambassador of Italian excellence and a symbol of vocal mastery, range, and interpretative agility.
All models in the series are distinguished by elegant design, noble materials, high-end components, and an execution that transcends mere listening.
To achieve this result, every element of the project has been subjected to rigorous listening tests.
Each model of the prestigious Callas Line is born from a perfect fusion of artisanal tradition – with cabinets handcrafted in our Italian workshops with meticulous attention to detail – and cutting-edge technologies.
Every model in the series is built using carefully selected fine woods and premium materials, together with components representing the state of the art in electroacoustics.
This ensures not only outstanding build quality, but also superior performance.
A defining feature of these speakers is the rear-firing system: two additional tweeters arranged in a natural dipole configuration.
This system enriches the reflected sound field without interfering with the direct signal, preserving transient accuracy and enhancing detail, balance, and brilliance – all contributing to an amplified and immersive perception of space.
All of this is the result of the passion and dedication of the Opera team, who have created a line of loudspeakers of the highest quality: captivating to behold and enchanting to hear.
