Floorstanding loudspeakers — Opera Loudspeakers Callas Diva

The Callas Diva is a floorstanding loudspeaker from Opera Loudspeakers, built with a moderate power requirement for its cabinet size. Opera Loudspeakers is an Italian manufacturer with a distinctive visual identity, generally favouring rounded, sculptural cabinet shapes over the conventional rectangular box most rivals use, and the Callas name references the celebrated opera singer in keeping with the brand's musical naming heritage.

Position in line

It sits below the Grand Callas in Opera Loudspeakers' range as a more accessible model beneath the brand's flagship tower. This positioning below the Grand Callas suggests the Callas Diva offers genuine access to Opera's distinctive engineering and design language at a somewhat more attainable scale and price than the brand's largest statement piece.

Key specs that matter

Rated response is 30 Hz to 25 kHz. Sensitivity is 90 dB into 4 ohms with power handling specified at 240 W. At 116 x 37 x 53.5 cm and 65 kg it is a substantial, heavy tower, its considerable weight consistent with the dense, curved cabinet construction Opera Loudspeakers is known for across its whole range.

Sound and use context

Expect a dynamic, refined presentation typical of Opera Loudspeakers' Italian engineering approach - the brand's distinctively rounded cabinet shapes are chosen partly for their acoustic benefits in reducing internal standing waves and diffraction, alongside the obvious visual distinctiveness compared with a conventional rectangular tower.

Pairing

The 90 dB sensitivity and 4 ohm load call for a mid-power amplifier with reasonable current delivery, worth confirming against whatever amplifier is already owned or planned for the system.

Alternatives

The Grand Callas sits above this model in Opera Loudspeakers' range as a larger flagship tower, worth the further investment if this model's already substantial 65 kg build and considerable scale still leave ambitions for Opera's most ambitious statement piece. Opera Loudspeakers relatively specialist market position outside Italy means seeking a dealer with genuine hands-on experience of the brand distinctive curved-cabinet engineering is worth the extra research effort before committing to a purchase. A dealer demonstration alongside the flagship Grand Callas helps clarify exactly how much additional scale the larger model buys for a specific room and budget.
