The Siena is a floor-standing system with a strong personality that perfectly illustrates RF’s innate ability to match elegance and performance. Its unmistakable lines are completed by one of the most sophisticated cabinets ever produced by Rosso, which allow the Siena to deliver excellent sound with optimal integration into any living room.

controlling cabinet vibrations

The aluminium cone woofers and paper cone midranges are held in place by means of a vibration-damping system that minimizes transmission of vibrational energy to the baffle.

This feature allows an efficient control of structure-borne vibration, resulting in authoritative, sharp and controlled low frequencies.

Furthermore, the top unit enclosure is decoupled from the lower woofers enclosure by high-tech viscoelastic discs, helping the midrange and tweeter reach the absolute optimum in sound clarity and naturalness.

modular closed box system

The multi-faceted trapezoidal top cabinet is designed to reduce internal standing waves and thereby minimize sound colorations.

The entire loudspeaker cabinet is made of high density fiberboard (HDF), which is internally enhanced by a layer of advanced acoustic damping material.
