Description
SIGMA ACOUSTICS · ORCHESTRA
Orchestra 2.8
The low end is reproduced by a dual 25 cm lightweight, fast woofer.
SONIC CHARACTERISTICS
The marvellous soundof temporal coherence.
Dynamic, tonal delicacy, detail: the characteristics one notices at first listen. Dual fast, lightweight 25 cm woofers ensure an authoritative yet nimble bass response.

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.
