Opera Grand Callas Loudspeakers; pair

The Grand Callas is Opera’s most refined three-way loudspeaker system to date, blending engineering precision, musicality, and architectural beauty into one adaptable design. With a nod to the revered Tebaldi and previous Grand Callas models, this fully re-engineered speaker combines serious performance with real-world flexibility. Powerful yet elegant, the Grand Callas delivers a richly textured soundstage with pinpoint clarity, whether you're near-field listening or filling a large space with music.

Rear Dipole for Spatial Precision

Opera’s natural dipole system uses two rear-mounted tweeters wired in series and out of phase. This setup energizes the room with high-frequency ambience while avoiding destructive interference in the main listening axis. The result is a more immersive and natural top end that maintains transient accuracy without sounding etched or aggressive.

Drivers That Do the Heavy Lifting

Scanspeak-built woofers with aluminum cones are optimized for accuracy and speed, capable of hitting 115 dB at 200 Hz without strain. The annealed polypropylene midrange features a long linear excursion and Excel-based magnet system for ultra-low distortion. At the top, the Scanspeak 9700 tweeter continues its reign as one of the finest dome designs ever made: air, sparkle, and control in equal measure.

Cabinet Engineering That Disappears

Despite their size, Grand Callas enclosures minimize coloration thanks to multi-density construction, thick internal bracing, and detailed damping. The midrange chamber is fully lined with pyramid-profile open-cell foam, virtually eliminating reflections and modal noise. All front-facing driver mounts are precision-milled to reduce air turbulence at the cone boundary.

Smart Crossover Architecture

Rather than three independent sections, Opera’s crossover combines the woofer and midrange into a compound mid-woofer system. This configuration ensures seamless phase integration while preserving the natural power response through the crossover region. High-quality components like Mundorf capacitors and MOX resistors keep the signal path pure.

Adaptable Room Positioning

A rear panel switch allows for subtle bass tuning to suit different placements: close to walls, corners, or asymmetrical setups. Blockable reflex ports further increase control, letting you voice each speaker independently to match the room’s behavior. Whether 20 cm or 2 meters from the wall, the Grand Callas adapts.
