Rosso Fiorentino electroacoustics - siena


The Flagship series introduces our masterpieces, the toughest challenges we decided to take on in loudspeaker design.


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 in the field of high-end loudspeakers, which allow the Siena to deliver excellent sound with optimal integration into any living room.

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.

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.

The front panels are made of 10mm thick cnc-machined aluminium.
This blend of mechanically different materials together with a comprehensive asymmetrical bracing architecture allows the drivers to operate with utmost clarity and dynamics, drastically reducing panel resonances.

Finally, the front panel is designed to house a supertweeter which is dedicated to the reproduction of the ultrasonic frequencies (up to 100kHz). Indeed, this driver further enhances the "atmosphere" and naturalness of the reproduced sound. Today, the availability of a highly extended frequency response as found in the Siena is even more interesting, with the advent of new digital formats alongside vinyl and compact disc.
