Product details

Opera Callas Diva Tower Speakers

Opera Callas Diva tower speakers, is the latest 3-way floorstander designed to replace its predecessor. Specifically crafted for smaller rooms, these speakers offer reduced volume levels and a flexible design that seamlessly adapts to various environments, delivering a captivating and dynamic audio performance.

Driver Units

The Callas Diva model boasts an 8-inch long-throw woofer, a 7-inch annealed polypropylene midrange driver, and a 1-inch Scanspeak 9700 tweeter, ensuring high-quality sound reproduction.

Back Radiation System

The innovative back radiation system, featuring 2 tweeters configured as a natural dipole, preserves the accuracy of transient response, enhances sound detail, and creates an expansive soundstage.

Easy Positioning

The Callas Diva's cabinet is uniquely shaped to facilitate a "close listening position," allowing listeners to enjoy a three-dimensional soundstage even when seated as close as a meter and a half away from the speaker. Additionally, the flexibility of these speakers extends to modifying low-frequency response by adjusting the reflex port.

Elevate your audio experience with the versatile Opera Callas Diva speakers, tailored for diverse listening scenarios.
