The Sonus faber is the “non plus ultra” of a dream. A concentrate
of experience, intuitions, hard work and design that finds its
meaning in rendering the music more vivid, natural and captivating.
A Sonus faber has never been previously designed considering such a
multitude of “points of view”. Besides the variety of solutions, the
result exceeds the sums of the elements involved. A design that
re-echoes a know-how as old as music, together with a vision of what
will come. An authentic the Sonus faber.
“Lyre shape” design,
dual side curvature, special cross grained okumè plywood, used
in a double thickness constriction layer damped configuration,
has significant advantages compared to the single curvature
variant used previously, in terms of low coloration.
Sub–structural plywood ribs are strategically placed for total
rejection of spurious vibrations and standing waves control.
“Anima legata” system, based on two clamshells, i.e. CNC
anodized machined avional “vibration conveyors” (on the top and
on the bottom of the cabinet) that “collect” the remaining
structural micro-vibrations coming from the cabinet walls and
the transducers, like the parabola of an antenna. The two
clamshells are rigidly connected by a special steel rod, a high
speed mechanical interface, the “Soul Pole”, that concentrates
the micro-vibrations to the “Multiple Tuned Mass Damper”, a
special custom device optimized to critically damp structural
resonances, by oscillating in anti-phase. The enclosure is
decoupled from the floor through a patent pending suspension
system, eliminating any acoustic feedback and any vibration
transmission to the listening room.
29 mm ultra dynamic linearity hybrid Neodymium/Samarium-Cobalt
Larsen/Goeller ring radiator, viscoelastically decoupled from
the main baffle board. Implemented with a natural wood acoustic
labyrinth rear chamber, with a mechanical anti-resonator
designed for this application.
180 mm cone neodymium magnet system driver with the 1.5”
voice-coil of the “well hung” type chosen for the advantages of
both the “under hung” and “over hung” designs. Special custom
blend cone made of traditional cellulose pulp, papyrus and other
natural fibers developed according to the most natural sound.The
basket is thoroughly optimized to eliminate any resonance, fully
CNC machined from solid billets of Avional and Gunmetal. The
combination of the two different metals allows eliminating any
mutual resonance. The same way as the tweeter, the midrange is
decoupled from the main baffle board.
260 mm woofers with a “sandwich” cone structure, high-tech
syntactic foam core and two external surface skins of coated
cellulose pulp. Designed to blend perfectly with the special
midrange, and at the same time to have absolute definition in
their range: the sandwich structure with outer paper pulp skins
has the same sonic character of the midrange cone. 3”
voice-coils on Kapton former allow an unlimited dynamic
performance and low hysteresis.
380 mm infra woofer sandwich cone structure with high-tech
syntactic foam core and two external surface skins in nano
carbon fibre for maximum rigidity and light weight. 4”
voice-coil optimized to have progressive damping, through the
use of both Kapton and Avional in the former, to control the
Lorentz currents proportionally to the excursion obtaining this
way the tightest available lows. To perfectly match the low-end
performance to different listening rooms it is possible to adapt
the SPL of the infra woofer.
SOUND FIELD SHAPER
Special patented Sound Field Shaping technology allows the
control of the direct/reverberant radiation of the Sonus faber.
The sound field shaping module can be optimized in terms of
azimuth and SPL.
SOUND FIELD SHAPER TWEETER
29 mm ultra dynamic linearity neodymium ring radiator dome
derivative driver. Optimized off-axis radiation for this special
SOUND FIELD SHAPER MIDRANGE
120 mm neodymium hexadyne magnet system, paper
pulp/papyrus/natural fiber cone driver, as used for the front
midrange. It is a classic Sonus faber choice, a 4th generation
derivative of the unit used on the original Minima.
Non-resonant progressive slope
design, optimized amplitude/phase response for optimal
space/time performance. The impedance at low frequencies is
controlled for a clear and amplifier friendly performance.
Maximum quality is used in terms of the components: mundorf
Silver/Gold/oil capacitors, Jantzen Cross coil inductors.
