OPERA CALLAS

Second-hand. In excellent conditions. No visible signs of wear. Comes with original packaging.

Opera Callas represents the perfect balance between craftsmanship and innovation—a bookshelf speaker designed to deliver a top-tier listening experience. The result of Opera Loudspeakers’ long-standing tradition, this two-way model stands out for its refined design and advanced technological research, both of which shape its distinctive sonic character. The cabinet, made from premium woods and finished with glossy veneers, combines aesthetics and functionality, minimizing internal resonances through a tapered rear profile and carefully selected damping materials. The front panel, covered in black leather, houses a 13 cm mid-woofer with a copper phase plug and a 2.5 cm Scanspeak soft dome tweeter, a configuration engineered to ensure a balanced and natural reproduction across the entire frequency range.

The crossover, developed with high-quality components such as Mundorf capacitors and MOX resistors, manages the transition between drivers with a crossover frequency of 2,000 Hz, optimizing tonal coherence and integration.

From a technical perspective, the speaker offers a frequency response ranging from 40 Hz to 25 kHz, a sensitivity of 89 dB, and a nominal impedance of 4 Ohms. Despite its compact dimensions, Opera Callas impresses with deep, controlled bass, delivering a solid and articulate low end that perfectly balances with the other frequency ranges. The stereo imaging is particularly wide and detailed, creating an immersive and realistic soundstage, while the dynamic capability allows for the appreciation of every musical nuance, whether at high volumes or in more intimate listening sessions.

Opera Callas is more than just a speaker—it is a refined musical instrument, capable of delivering a rich, natural, and fatigue-free sound. Its exceptional craftsmanship and design solutions make it an ideal choice for those seeking a high-level listening experience.
