Orchestra 2.6
The evolution of the Orchestra 2.3. AMT NeoKapton tweeter, zeta-carbon midrange, 12" woofer.
Sonic characteristics
Elegant imageryand musical scores.
Created to move like an orchestral ensemble: delicate and refined in the pianissimos, explosive and exciting in the most dynamic moments. True sound, true emotions.
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.
