Product Description

Opera Grand Callas is a three-way floorstanding speaker that replaces the previous model with the same name.

Opera Tebaldi

The name is about all it shares as it has been completely redesigned from top to bottom; making it more comparable to Opera's previous flagship, the Tebaldi. Where the Tebaldi was large and could be difficult to place, the new Grand Callas has a much smaller footprint and is less-sensitive to placement.


This low-range loaded reflex design uses two 8" long-throw woofers, a 7" annealed polypropylene midrange and a 1" Scanspeak 9700 tweeter. The diffuser is complemented by a rear radiation system that uses two tweeters configured as a natural dipole. These rear-firing drivers increase the ambient sound, giving depth and substance to the musical performance.

Key Features

- Floorstanding speaker design in 2 wood finishes
- Three-way configuration, Bi-wirable
- Mid-range with polypropylene re-cooked cone & phase plug
- Scanspeak tweeter handles high power w/o ferrofluid for greater detail
- Rear-firing radiation system diffuses sound to improve ambient sound
- Finished in high-quality wood and leather
- Support for spikes or wheels

Press Reviews

  • 'The 92litre Grand Callas II is not simply imposing but also immaculately finished... Commensurate with its imposing stature the Grand Callas II serves up a massive soundstage with a rich, deep and visceral bass.' (Hi-Fi News, April 2016)

  • 'I found myself in my element listening to rock, electronic and large-scale orchestral works alike, the speaker proving adept at moving satisfyingly ‘grand’ chunks of air... The bass end is deliciously tight, even and well extended.' (Hi-Fi News, April 2016)

  • 'A notable strength of the Grand Callas II is its fine overall tonal balance… It sounds open and airy while high frequencies appear smooth and delicate, almost mellow.' (Hi-Fi News, April 2016)

  • 'Needless to say the loudspeaker’s impressive sense of scale worked wonders with all manner of (sensitively balanced) electronic… for the money Opera Audio’s Grand Callas II is mighty grand. A pair spaced well apart creates a creditably holographic soundstage with an almost lifelike scale.' (Hi-Fi News, April 2016)

  • 'Music lovers wanting a ‘dream speaker’ without contemplating taking out a second mortgage should certainly put Opera Audio’s latest Grand callas high on their shortlist for auditioning.' (Hi-Fi News, April 2016)
