Sonoro GRAND ORCHESTRA – Precision that gains space
Homogeneous dispersion characteristics through intelligent two-and-a-half-way concept
With the GRAND ORCHESTRA, Sonoro presents a floor-standing loudspeaker that combines technical sophistication with musical sovereignty. The well-thought-out two-and-a-half-way concept ensures a particularly homogeneous dispersion characteristic with high sensitivity – a combination that enables both detail and dynamics without overtaxing the amplifier.
Optimized impedance for versatile amplifier combinations
The impedance, optimized across the entire frequency range, additionally contributes to stable and controlled reproduction. Especially in combination with various amplifier types – from compact transistors to finely tuned tube electronics – the GRAND ORCHESTRA proves to be pleasantly uncomplicated and versatile.
Precise timing and spacious stage imaging
Sonoro relies on targeted measures to improve timing and spatiality in its design: the rearward-sloping baffle, the deliberately offset Air Motion Transformer (AMT), and a carefully tuned crossover enable precise instrument localization and a remarkably wide, credible soundstage. The optimized waveguide of the AMT effectively reduces sound interferences and edge diffractions – the result is a wide, even dispersion with stable sound balance even outside the ideal listening position.
Low-resonance HDF cabinet design
The cabinet, made of high-density fiberboard (HDF), largely avoids parallel surfaces, thus minimizing standing waves and cabinet resonances. This constructive consistency immediately pays off in the form of clean, controlled reproduction that retains its structure even with complex musical material.
Slim floor-standing loudspeaker with high musical sovereignty
The GRAND ORCHESTRA is thus a living-room-friendly floor-standing loudspeaker that performs acoustically well beyond its price range – and convinces with remarkable composure even on smaller or acoustically sensitive amplifiers.
