The the Sonus faber SE17
After 8 years, their skills and knowledge evolved so much that they clearly felt the opportunity, and the necessity, of turning the original the Sonus faber into something even more performing. They understood that all the ideas and constructive solutions used for the Sonus faber contributed to achieving an extraordinary object, but somehow a “work in progress”.
Here the Sonus faber SE17 is born, featuring fundamental changes that made it great.
The most radical among the new changes is the selection of all-new driver system for the reproduction of the mid-high frequencies. For the front tweeter, they used the most ambitious and the most exclusive transducer ever made by our laboratories, the Ex3ma tweeter, developed in 2014.
This tweeter has the peculiarity of being the first, in the history of high fidelity, based on a diaphragm in Beryllium, but modified from a physical point of view to obtain even better results in exquisitely musical terms. In fact, the Beryllium has a tone with metallic characteristics that often make listening unpleasant.
A diamond surface treatment was carried out; therefore, a layer of Diamond Like Carbon is deposited on the diaphragm surface. The added value of this surface coating is its ability to give the Beryllium some of the typical properties of diamonds, the main one of which is hardness that gives the dome further rigidity, moving this way higher its own resonance frequency, where it is impossible to be heard.
This change allowed them to obtain the desired sound result, a very fast and detailed sound, absolutely airy. Long story short: a natural sound.
Then they used the best midrange available, the one developed for Lilium, based on an air-dried cone starting from a mixture of cellulose pulp and other natural fibers such as Kapof and Kenaf; the maximum expression of our development. This speaker is then reinforced with an Avional and Gunmetal basket, used for the first time in the original the Sonus faber and now enhanced by a no-compromise Neodymium magnetic motor system.
While maintaining the same woofers and subwoofers, the reproduction of the low and ultra-low frequencies of the Sonus faber SE17 has been improved thanks to the total remake of acoustic treatments of each transducer’s acoustic environment and implementing the Stealth Reflex system itself.
Sonus Faber have essentially improved the quality of the absorbent material and its placement, as well as re-tuning the individual acoustic chamber.
Last but not least, they were able to benefit – at the time of the original the Sonus faber was not available yet – from our anechoic chamber, and this allowed us to redesign the crossover circuitry from scratch and improve a lot of parameters related to linearity, speed, transient response and impulse response.
The result is the Sonus faberSE17, a loudspeaker with the same overwhelming power of the original, with all the same technical solutions, but much faster, transparent, articulate and defined, with a truly optimal space/time performance.
The the Sonus faber SE17 is a loudspeaker in some ways absolute, unique and unrepeatable…”
