Opera Grand Callas Floor Standing Speakers – Made in Italy

$24,000.00 inc. GST


‘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.’

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


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.

If you are looking to buy a complete Hi-Fi system we recommend Opera speakers with Unison Research electronics as a match made in heaven
