Rosso heritage in a bookshelf format.
The Arno20 delivers an authentic, uncolored listening experience, preserving the sound’s character as envisioned by the artist and sound engineers.
This is achieved through a custom 6.5” woofer, developed in collaboration with a renowned Italian manufacturer, featuring a treated paper diaphragm with a silky outer layer and a stiffer inner core that ensures fast, natural midrange response. The powerful ferrite magnet, large voice coil, and over-damped reflex system work together to provide deep, articulate bass, while the tweeter, inspired by our flagship Siena model, ensures remarkable clarity and consistency across a wide listening area.
The multi-layered cabinet reduces resonance, blending outstanding acoustic performance with Italian craftsmanship, while the premium crossover components bring every subtle detail to life with precision and musicality.
