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.\u003c\/p\u003e\n\u003ch5\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrue three-way design\u003c\/strong\u003e with dedicated rear dipole radiation system\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo 8\" long-throw woofers\u003c\/strong\u003e with aluminum cones and SD1 flux stabilization\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e7\" annealed polypropylene midrange\u003c\/strong\u003e with SEAS Excel motor system\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1\" Scanspeak 9700 tweeter\u003c\/strong\u003e with dual decompression chamber and no ferrofluid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear-firing tweeters\u003c\/strong\u003e wired as a natural dipole to enhance ambience and space\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour possible bass tuning configurations\u003c\/strong\u003e via reflex duct blockers and switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeparate internal chamber\u003c\/strong\u003e for the midrange with precision acoustic treatment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavyweight cabinet\u003c\/strong\u003e with curved MDF and multilayer plywood panels up to 50mm thick\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandmade in Italy\u003c\/strong\u003e with luxurious wood and leather finishes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eRear Dipole for Spatial Precision\u003c\/h5\u003e\n\u003cp\u003eOpera’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.\u003c\/p\u003e\n\u003ch5\u003eDrivers That Do the Heavy Lifting\u003c\/h5\u003e\n\u003cp\u003eThe two 8-inch woofers are made by Scanspeak to Opera's specifications, with aluminum cones. The annealed polypropylene midrange has 12 mm of linear peak-to-peak displacement, which Opera says is what it takes to reach 115 dB at 200 Hz while keeping intermodulation distortion very low, and its magnet uses the SEAS Excel design, with copper rings above and below the T-shaped gap. At the top, the Scanspeak 9700 tweeter, which Opera calls one of the best tweeters ever made and, in some respects, still unsurpassed.\u003c\/p\u003e\n\u003ch5\u003eCabinet Engineering That Disappears\u003c\/h5\u003e\n\u003cp\u003eThe MDF and curved plywood cabinet runs from 25 mm at the sides to 50 mm at the front, and inside it is braced to connect the four vertical walls. 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.\u003c\/p\u003e\n\u003ch5\u003eSmart Crossover Architecture\u003c\/h5\u003e\n\u003cp\u003eRather 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.\u003c\/p\u003e\n\u003ch5\u003eAdaptable Room Positioning\u003c\/h5\u003e\n\u003cp\u003eA 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. Opera specifies at least 20 cm from the rear wall.\u003c\/p\u003e\n\u003ch5\u003eThe Listening Room Difference\u003c\/h5\u003e\n\u003cp\u003eAt The Listening Room, we don’t just sell loudspeakers, we help you build a system that sings.
