pure performance in a compact size

It’s the modern connoisseur’s choice, a simple pair of compact high-end passive hi-fi speakers able to bring superb, breathtakingly realistic sound even to small listening rooms.

Fiesole is a classic Rosso Fiorentino, our first design with which our company started back in 2007. Since its first release Fiesole has been greatly appreciated for its pristine sound, musicality and distinctive design. We knew it wouldn’t be easy to update our ‘founder model’.
Fiesole series 2 is therefore the result of the implementation of our latest technologies and expertise always carried out with great respect for the achievements reached by its predecessor.

Fiesole was the first Rosso speaker to implement the concept of using mechanically different materials in one composite structure where each material absorbs and damps the resonant frequency of another material in the system. The result of this ‘team work’ is a cabinet incredibly still and firm where panel vibration modes are drastically reduced revealing great micro and macro dynamic details in the sound.

This concept has been further developed in the Fiesole series 2 by adding extra aluminium panels on the sides, new and advanced internal damping pads and a bracing system that, implementing a firm connection with the midwoofer magnet, significantly reduces the transmission of unwanted vibrations from the driver to the front baffle.

Fiesole is a two-way rear vented design. All the transducers are held in place in the rigid and damped sandwich front baffle made of thick aluminium and HDF layers.

The 6.5” woofer is powered by a lightweight long-throw voice coil and a vented ferrite magnet system. Its cone material is Nomex paper and provides great stiffness and excellent damping properties showing a very smooth response at mid-high frequencies. Inside the enclosure different types of absorbing material together with a highly scattering sound surface take care of the modal resonances voicing the midwoofer with an exceptional neutrality.

At the top of the front baffle sits the “ribbon/soft dome” section, a Rosso trademark, which combines the silk dome tweeter with our new ribbon ultrasonic generator for an amazing detailed and extended high frequency response.
The wide dispersion of the new ribbon ultrasonic generator perfectly complements the smooth and detailed Italian 28mm neodymium silk dome tweeter and starts to function at around 30 kHz and goes all the way up to 100kHz. The resulting wide-bandwidth performance greatly enhances the “atmosphere” and naturalness of the reproduced sound, giving it a truly three-dimensional quality. Nowadays, the highly extended frequency response found in the Fiesole is even more interesting, with the increasing diffusion of high-resolution digital formats alongside vinyl.

High End sound details

There is life above 20kHz...

and that is why we designed our own ultrasonic generator,  a  4mm thin aluminium ribbon driven by a large neodymium magnet and capable of reaching ultrasonic frequencies up to 100kHz. With its great off-axis dispersion and accuracy in producing the leading edge of each transient, the supertweeter makes the whole system sound more natural, giving the reproduced sound a truly three-dimensional quality.

our binding posts

With speakers as ambitious as the Rosso Fiorentino models, attention to detail comes naturally. In order to optimise the retrieval of low level detail in the music we decided to design our own binding posts, selecting our own mix of precious materials and carefully checking each step of production. We are proud to say that this whole process is made in Italy and partly in our own laboratory
