Art of a New Era.

+ Wishlist

The wealth of knowledge gained through the research and development of the the ambitious ‘The Sonus faber’ project was instrumental in allowing us to utilize innovative and extraordinary new techniques and functional solutions in the design of the Aida.  A speaker as grandiose as an opera by Giuseppe Verdi, able to revolutionize and yet express the core virtues  of its creator.  A speaker born from the heart of the Team, able to reveal how much Sonus faber is evolving and yet maintaining its original spirit, combining tradition with technological innovation.

From the fusion of tradition and
technological innovation comes
the beauty of a new era.

Like “Aida”, the greatest expression of Verdi’s talent, which blends the tradition of Italian melodrama and the innovation of abandoning convention, so too is the Aida project a blend of tradition and innovation. A synthesis that expresses beauty and vision. 



    “The “Stealth Reflex” system, derived from “The Sonus faber”, is an innovative and patented “para-aperiodic” interpretation of the tuned load. Besides allowing for reduction in the dimensions of the acoustic volume, it provides greater extension in low frequency response and dramatic reduction in distortion.  It also #eliminates spurious wind noises, typical of traditional reflex systems, substantially contributing to the correct reproduction of silence.”


    Taking inspiration from resonance control systems in Formula One racing, cutting edge research in the control of cabinet resonance has led us to a bold new approach.The upper and lower “Dampshell” in Aida, are milled from massive slabs of avional aluminum.  They act to dampen any spurious vibration in the tuned wooden #chamber while maintaining the advantageous properties of wood. Similarly, each of the internal driver chambers is structurally grounded to a non-magnetic steel alloy rod we call the ‘Anima Legata’.  This vertically oriented device is bound to a pair of tuned mass dampers at critical nodal points which are painstakingly  tuned #to optimal tension for the maximum thermal-kinetic conversion of residual micro vibrations.  Not unlike systems used in highly sophisticated racing and recent skyscraper projects, the Tuned Mass Damper system used in the Aida dissipates structural resonance with unmatched efficiency.


    The perfect reproduction of silence cannot be obtained by solely developing and devising a totally inert acoustic case, the management of the interaction between the speaker and the environment must be addressed as well. This is why Aida is mechanically decoupled from the floor with a hybrid of  the patented Z.V.T. Zero Vibration #Transmission system and our new Bow Spring® suspension technology which uses a folded “crossbow” in controlled flexibility and progressively yielding elastomer as the base of the speaker.  This system not only totally reduces the transmission of spurious vibration into the the listening environment and prevents#adverse phenomenon such as acoustic feedback, but also elevates the entire cabinet allowing the infra-woofer to function freely in a “ground-effect” with optimal propagation and dispersion of  low frequency emissions.

  • Sound Field Shaper

    Aida is capable of reproducing music with the immense scale of a full orchestra with heart-pounding immersion, without losing the spatial coherence to float a single voice in the middle of your room with hair-raising realism.  To help achieve these feats in a range of listening environments, we implemented the rear-facing tweeter#and midrange array known as the Sound Field Shaper.  This attenuated driver array allows for calibration of the ambient response of your room, ensuring that regardless of of the reflective, dampening or diffusive qualities of your listening environment, the verisimilitude of your music is not lost.


    Aida’s case is a complex system that inherits its structural concept directly from “The Sonus faber”. The dual “waved” curvature typical of the shape of the “lyre” creates a geometry that, compared to previous solutions, substantially increases structural strength and guarantees exceptional management of the energy#produced inside the acoustic chambers by the drivers. The complex damping system adopted further removes any possible final resonance: both the internal walls and the outside “wings” have dual curvature in multi-layered cross-veined okoumè plywood and are technically implemented through a decoupling system# consisting of a foil in a viscous-insulating material, thus making use of the “constrained layer damping” technique to the fullest. The “acoustic environment” of each single transducer is then optimised to as close to theoretical perfection as possible: on one hand  specific reinforcing structures are strategically#placed within each individual acoustic space and, on the other, each one of these is insulated with different materials, from open cell thermoplastic foam to fibrous materials, similar to the felt used in pianos, selecting the most appropriate material or materials for each specific application.


    With this simple statement we want to reiterate that the total credibility of music reproduction implies the perfect reproduction of one of its essential components: the space between one note and another, that is to say “silence”. In electro-acoustics by “silence” we mean the removal of all vibrations and spurious sounds#that can contaminate the purity of the musical message. Correct reproduction of silence should be, therefore, the final frontier for a state of the art speaker system. The best way to achieve this objective is to painstakingly focus on the design and development of the acoustic case, implementing tested solutions in order to#eliminate all vibrations and spurious noises that damage the integrity of the sound.

Lyra shape design, dual side curvature, special cross grained okoumè plywood, used in a double thickness constriction layer damped configuration. Sub–structural ribs strategically placed for rejection of spurious vibration and standing waves. Two “damp-shelves” CNC anodized machined avional aluminum vibration dampers stiffen the column structure reducing structural micro-vibrations.  The “Anima legata” system encompassing the 3 inner chambers of the front firing drive units. A special high speed mechanical interface, concentrates the remaining micro-vibrations conveying them to the dual multiple Tuned Mass Dampers, i.e. two differently tuned special custom devices optimized to erase micro-vibrations, by oscillating in ‘anti-phase’. Proprietary floating bridge “Bow spring” suspension for vibrational interface devised to decouple the enclosure from the floor through the Zero Vibration Transmission technology, a patent pending suspension system, eliminating any acoustic feedback and any vibration propagation to the listening environment.

To further inhibit any residual cone coloration, a transparent viscous surface damping coating is implemented. The basket is thoroughly optimized to eliminate any resonance, thanks to a high-tech dual metal (Avional and Gun Metal), CNC machined from solid billets. The combination of different materials, offsets any mutual resonance. As with the tweeter, the midrange is decoupled from the main baffle board and designed synergistically with an optimized “acoustic chamber”. A special coaxial anti-compressor is used, designed to remove cavity resonance and distortion.

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. A long-throw motor system with a 2” controlled voice coil is implemented for high speed, performance and linearity. Special coaxial anti-compressors are used, designed to remove cavity resonance and distortion.
