Sigma Acoustics · Orchestra
Orchestra 2.2
Derived from the 2.3 with more compact dimensions for smaller listening spaces.
Sonic characteristics
Noble musical atmosphere.
Dynamics, tonal delicacy, detail: the characteristics one notices at first listen. The search for perfect symbiosis with the room, from the first watt to live-performance dynamics.
The drivers
The synergy of drivers.
The Heil tweeter — Air Motion Transformer — is recognised as one of the finest high-frequency drivers of any era: the speed with which it creates sound and returns to silence gives a sense of tangible presence.
The cabinet
Form serves only the sound.
A perfect fusion of aesthetic form in pure service of sound, with diagonal routing and curves that distribute the energy emitted by the drivers. Multi-layer hardwood veneers and high-density MDF, each calibrated to absorb or resonate at critical frequencies.
