The re-birth of a myth and the celebration of 30 years of History.

Extrema is the most front-running project in the history of Sonus faber. It is a milestone on its development road, one of those maximum expressions in the design of acoustic speakers that has become a myth for all enthusiasts. The maximum possible performance and perfect sound reproduction were the factors that guided its development, both for design and in the electro-acoustic project. In its 30 years of history, Sonus faber has produced various successes, and it has developed greatly in technological research and the use of materials, but it has always remained faithful to its DNA and its traditions. This is why, to celebrate its 30th anniversary, Sonus faber decided to pay homage to its most «extreme» project, remaining perfectly adherent to the intentions that characterised its creation, but integrating it with the new technological development, electro-acoustic research, design and material use frontiers.

In 1991 Extrema (Ex3ma) became one of those maximum expressions in the design of acoustic speakers worldwide. This is why Sonus faber decided to celebrate its 30th anniversary paying tribute to its most “extreme” project.

EX3MA’S SHAPE

The wiry shape of the speaker breaks on purpose the tradition of the soft lines that characterize Sonus faber products. It’s been obtained using a reduction process in which the volume was extracted from a block of rigid material.
As marble under the skilled hands of the sculptor, the raw material has been broken to obtain clean cuts and tight surfaces. Ex3ma is for performance without compromises and its dynamic lines mirror its character and nature.

CROSSBREEDING AND COUPLING OF DIFFERENT MATERIALS

In Ex3ma every single material used has a particular meaning for Sonus faber. The Carbon Fiber monocoque recalls the experience gained with the Pagani Huayra premium audio system; the sides made in Red Spruce from the Val di Fiemme quotes the Italian violin making tradition; Avional and Ergal (Aluminium alloys) gives continuity with the Sonus faber products and provide further rigidity to the overall structure; the Beryllium represents the research and the experimentation.

FEATURES

It is an extreme project that aims without hesitation at the maximum possible resolution, but it must also be simple with a single cut in frequency and with only two active loudspeakers, and the passive radiator dampened, as the original Extrema was.

THE CARBON FIBER

Carbon, a very particular chemical element at the base of all the life on our planet, is present in nature in various forms, from the softest such as graphite to the hardest such as diamonds.Today used in multiple environments, from aeronautics to vehicles, medicine and sport, carbon is well known to Sonus faber, which experimented its characteristics when producing the Huayra sound system, the latest model of supercar made by Pagani Automobili from Modena.

THE PASSIVE RADIATOR

Fully designed by Sonus faber, the L’E.M.B.A.B.R (Electro Magnetic Brake Auxiliary Bass Radiator) has varied dampening. The flat piston diaphragm is optimised for this application, and is positioned structurally midway between the sandwich structures of the midwoofer cone and the «monocoque» structure. The basket is fully optimised to eliminate all resonance, thanks to the use of two high technologymetals (Ergal and Gun Metal) that are machined in CNC from the solid piece. The combination of these two metals eliminates any reciprocal resonance.

THE ULTRA LOW FREQUENCY AND ITS MANAGEMENT

The passive radiator is also fully designed by Sonus faber; the L’E.M.B.A.B.R (Electro Magnetic Brake Auxiliary Bass Radiator), according to Engineer Cadawas, has varied dampening. The flat piston diaphragm is optimised for this application, and is positioned structurally midway between the sandwich structures of the midwoofer cone and the «monocoque» structure. The basket is fully optimised to eliminate all resonance, thanks to the use of two high technologymetals (Ergal and Gun Metal) that are machined in CNC from the solid piece. The combination of these two metals eliminates any reciprocal resonance.

CHASSIS

The chassis’s maximum rigidity and resistance has been guaranteed using the most advanced technology available for laminating the Carbon fiber, with different multilayers wood cores in between. The complex mold with 6 elements used to create the speaker frame is made to measure, making the standard production of the object extremely limited, adding exclusiveness to the character of this loudspeaker.

THE BERYLLIUM D.L.C. TWEETER

Beryllium is an extremely rare and exclusive metal that is used in various high-technology industrial sectors, such as medicine and aerospace. In Ex3ma it’s used for the creation of the tweeter dome and it’s treated in surface with a vaporization of Diamond («Diamond Like Carbon»). This chemical process allows to maintain the mechanical characteristics of Beryllium, improving its musicality.

BERYLLIUM AND DIAMOND

Beryllium is an extremely rare and exclusive metal that is used in various high-technology industrial sectors, such as medicine, aerospace and experimental/applied physics. Beryllium also played an important part in the history of audio transducers, used for example in magnetic cartridges.

THE HIGH FREQUENCY

Reproducing high frequencies is entrusted to a 30 mm transducer with mobile coil designed entirely by Sonus faber, implemented with a Sonus faber mechanical interface that optimises vibration management.The «Ultra dynamic linearity», the result of the new Neodymium magnetic system, is optimised by the dome diaphragm of DLC (Diamond Like Carbon) Beryllium to obtain the maximum resolution possible in acoustic reproduction.

WOOD

The art of lute making has always been a source of inspiration for the design of many of Sonus faber most emblematic speakers; it is not by chance that all the precious elements of the Homage collection, from Amati to Guarneri and Stradivari are named after the most famous lute makers in history. The new Ex3ma pays an important tribute to this antique art by flanking, in close contact with the ultra-modern carbon chassis, sides of red spruce from Val di Fiemme, the wood of string instruments par excellence.

THE SIDES

The sound of wood has always been important for Sonus faber. In the case of the Extrema project, the fact that the supporting structure of the loudspeaker is made with a carbon monocoque make it possible to use wood as the pure resounding element, exactly as in the sound board of string instruments. The choice therefore had to be the resonant spruce from Val di Fiemme, the rare and prestigious essence of which violins are made.

IL MID-WOOFER

The 180 mm “Ultra dynamic linearity” mid-woofer is designed by Sonus faber and equipped with a Neodymium motor. A pure copper winding 6N is used on a coil support with control of the Lorentz currents. The magnetic motor, very linear and dynamic, has an optimized layout and a heat dissipater that also acts as a «mass damper». The special diaphragm is obtained by means of a sandwich that uses nano-carbon hides and a special syntactic dampening foam to obtain maximum resolution.

THE MEDIUM AND LOW FREQUENCY

The 180 mm “Ultra dynamic linearity” mid-woofer designed by Sonus faber and equipped with a Neodymium motor, is the driver that reproduces the medium and low frequencies. A pure copper winding 6N is used on a coil support with control of the Lorentz currents. The magnetic motor, very linear and dynamic, has an optimised layout and a heat dissipator that also acts as a «mass damper». The special diaphragm, which is personalised for Sonus faber, is obtained by means of a sandwich that uses nano-carbon hides and a special syntactic dampening foam to obtain maximum resolution.

 

CROSSOVER IN AIR

Ex3ma uses a precious non-resonant crossover in air with progressive slope, optimized by module and phase for the best space/time behavior. The «paracross» topology is combined with best quality components that exalt the sound quality: Mundorf Supreme capacitor and Jantzen inductors. The crossover frequency is 2350 Hz, and the low frequencies can be dampened in 4 different ways, according to the listening room.
