Orchestra 2.3
The search for perfect symbiosis: because not all rooms are the same.
Sonic characteristics
Synergy, detailand sonic pleasure.
Being in symbiosis means listening at low volume with the soft sounds of the first watt, or being moved by raising the volume to recreate with force and dynamics the sensation of live sound.
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.
