Opera Callas Diva Floor Standing Speakers – Made in Italy


The new Callas Diva model is a three-way floor standing speaker that replaces the previous model with the same name. It has been completely redesigned. The performance of the new Callas Diva is at the level of the Grand Callas model but with a significant reduction in volume to be used in smaller rooms. The low range, reflex-loaded design, uses one 8 inch “long-throw” woofer, while the mid-high range is reproduced by a 7″ annealed polypropylene midrange and by the 1″ Scanspeak 9700 tweeter. The diffuser is complemented by the back radiation system that uses two Tweeters configured as a “natural dipole”.

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
