We have moved to a purpose built workshop Stirling, despite what Google says we are still open, also our telephone number has changed, see below.

I now full offer tonearm repairs following extensive training by John Nielson of Audio Origami fame,  Linn Ittoks and Naim Aro’s are our speciality, but I work on just about any arm, and none have so far defeated me.

if you wish to discuss your repair, or any other questions please call on 01786-940020 or email

Rosso Fiorentino Florentia


The Rosso Fiorentino Florentia Floorstanding Loudspeaker, is the Italian Statement Loudspeaker. The Flagship of the range, bold, uncompromising and unconventional.

In a field still full of conservatism and mostly curve-shaped designs, the Florentia stand up like a modern architectural monument. Its physical presence and the strength of its straight and angled lines convey a great sense of power and dynamism which is, however, balanced by its precious material and construction details which reveal its noble and refined character.


The Florentia is made up of three separate modules. The upper and lower sealed sections house respectively the mid-bass and bass drive units, while the middle open baffle section contains the midrange and treble drive units and the crossover.


The emotional body feeling experience of music typical of certain rock/pop live performances or the real and embracing sonic presence of a classic orchestra can only be faithfully reproduced starting from the very low frequency range.
In the Florentia, 2 x 12 inch proprietary subwoofers are housed in the lower sealed section, covering sub-bass range to below 20 Hz.
The box incorporate an extensive bracing making use materials with diffrent mechanical properties so as to drastically reduces structure vibrations.

These impressive ‘made in Italy’ transducers are the result of a design partnership with one of the leading international driver manufacturers, B&C speakers. They make use of a powerful, vented full neodymium magnet system and are especially designed to easily handle extremely high excursions and very low air compression.

Each driver is then indepently driven by a 1050 watt digital amplifier which provides a great power reserve for amazing dynamics and control at the very low frequency range. With its possibility of DSP adjustments Florentia will easily adapt its very low frequency emission to the acoustics of the listening room.


Two midrange drive units, one soft-dome tweeter and one ribbon ultrasonic generator are integrated into the solid, CNC-machined aluminium-hdf sandwich middle panel which is also sculpted to reduce diffraction to minimal levels. The midrange units operate in a special open baffle structure which eliminates the typical resonant problems that hamper most midrange enclosures causing the sound to take on a coloration.


The top and bottom panels of the open baffle module are designed at different angles to the speakers and padded with absorbent material in order to reduce resonances at mid range frequencies. The back of the middle panel is designed to reduce diffraction at mid frequency to minimal levels. The result, together with the open baffle system, is a natural and clear sound with excellent depth and open soundstage performance.


Placed inside and at the back of the middle module, the crossover, the ‘heart’ of the system, consists of three separate well-aired sections. This multi level structure is entirely hand-wired using  audiophile grade components from well known specialized companies together with some of our special custom made elements. A set of fine tuning controls are also present to allow the output of the relative sections to be increased or decreased in order to compensate for the different acoustic characteristic of the listening rooms.


Regarding the high frequency range, even the most demanding recordings will be faithfully reproduced with all musical details thanks to the match between the tweeter and our own supertweeter which complement each other with their frequency ranges and sound dispersion characteristics to achieve an absolutely homogenous and ‘three dimensional’ reproduction.


The upper module houses a customized 10 inch woofer which features an extreme coil excursion with low distortion and excellent transient response. This very balanced engineered driver covers frequencies from around 60Hz up to 200Hz where fundamentals of a lot of acoustics instruments reside. Its placement on top of the other elements drastically reduces the first floor reflection thanks also to the use of a controlled dispersion pattern  crossover design.
This section, like the others, is decoupled by the use of rubber inserts in order to reduce the transmission of vibrations  and the interferences between each module.
The internal bracing structure together with very low cabinet losses led this box to have a considerable QTC value of 0.71.

Rosso Fiorentino is more than just a loudspeaker manufacturer.
RF is enthusiasm for the magic that happens every time we create a sounding machine, it’s a way of life, it’s love for music and for its ability to stir emotions and bring people together.

From the very beginning I wanted RF to be different from the other brands for its absolute acoustic performance, refined craftsmanship and Italian elegance. With the Rosso Fiorentino systems, I wish to convey our culture to the listeners, a culture that is deeply rooted within all members of our company, and which is based on a common passion for live music, an academic background in electroacoustics, and the instinctive pursuit of elegance.

Our is a Tuscan company and from our history and culture we draw inspiration to always look for new ways to improve ourselves. Our loudspeakers embody the soul of the place where they are made. Their sound reflects the character of our land… straight, essential, always caring for proportion and detail, made to last.
Francesco Rubenni


Elegance is a very important aspect of our life, a balance between innate good taste and precise choices, care for the essence and meticulous attention to each detail.
Here at RF we always look for elegance in the design. This means that our style is more than a set of aesthetic traits, it is a collaborative work between designers and engineers searching together for the ‘necessary beauty’ where every line and proportion is conceived to reach the desired acoustic performance as well as to visually reveal the characteristic of the loudspeaker system.

Francesco Rubenni and his collaborators are driven by an unparalleled passion for music and electroacoustics. Every new project is a challenge, a constant research looking for new ways to reach a better performance but at the same time never forgetting their final target…the emotional pleasure of listening to music.

We like to think of our design as the result of a deep technical understanding of how loudspeakers work and the client’s desire for an involving and breathtaking listening experience.


The design of RF models is carried out by Francesco and his collaborators. Francesco follows every step of the creative process, from the initial ideas to the first sketches on paper, which then become technical, computerized and eventually ready for simulations and optimisation of the production methods and processes.

At the prototype stage, the design becomes a physical shape and the long process of measurements, listening and fine tuning takes place. During this part of the work Francesco uses all his expertise and passion to model the sound and to improve every single technical parameter of the loudspeaker.

However, as we all know, a dream never comes true unless it is shared with others.

During the listening session all the RF team joins in , but that’s not all, at this stage the involvement of our musician ‘friends’ becomes really important. Involving them in the tuning  of our system, in making recordings, in listening back,  in trying different technical solutions, enables us to make well balanced loudspeakers capable of playing any kind of music and evoking deep emotion in the listener.


Rosso Fiorentino (Giovan Battista di Jacopo, Firenze 1495 – Fontainebleau 1540) was one of the most talented and unconventional Florentine artists of the early 16th century.
He assimilated the innovations of Leonardo, Michelangelo and Raffaello but went on to experiment with a freer technique and more abstract forms.
His paintings forcefully express the strength of the colours, the sophisticated interpretation of the details, the luminosity of the reflections and an underlying artistic rigour.
The gauntlet he threw down to those who had already interpreted all there was to interpret is something that intrigues us and inspires our work daily.
