Delta Butterfly One

Really Hi-End loudspeakers system of reduced dimensions, they are able to offer a true highly dynamic sound in every listening environment.
To facilitate their use in smaller rooms their emission has been optimized both for near rear wall installation and free space.
30° toeing in toward the listening position also facilitates Horizontal NPS© emission.


Among the exclusive Butterfly characteristics we can point out:


The proprietary Butterfly© anti-diffraction system.
The front and rear panels professional damping finish.

The internal division of the loading volume into two connected triangular sub-volumes Delta System©.



The cabinet totally resonance free, due to Delta System©, lead plates complete internal lining and damping finish.
The total exclusion of any added elements that might introduce a negative effect on acoustic performance (as, among others, a front grille).
The crossover network, electrolytic capacitor free.
The 24 kt gold plated input connectors that allow for both bi-wiring and bi-amping.
