For the diaphragms, as is usual, the use of natural materials such as silk dome for the tweeter and cellulose mixtures for the midrange and woofer prevail. In detail: 29mm dome Tweeter containing DAD technology and neodymium magnet, derived from the development of Aida; 150 mm Midrange with a cone made of a proprietary mixture of cellulose, kapok and kenaf; 180mm Woofer with a cone constructed from a sandwich of cellulose pulp membrane and rigid syntactic foam. The Crossover is the result of detailed computer research and careful tuning by ear. It is comprised of components selected from the finest international producers. The Bass Reflex system is the innovative soul of this project, and is designed in particular to ensure speed in the articulation and extension of low frequencies. It is a sophisticated approach to Bass Reflex design starting from concepts in aerodynamic management of laminar flow as expressed by Onken and Jensen during the golden age of High Fidelity. These concepts, further evolved by Sonus faber, introduce elements that are profoundly innovative, such as the Stealth Reflex system. Invented by Sonus faber and currently implemented in the models The Sonus faber and Aida, the hyperbolic shape of the duct has led to the ‘duck tail geometry’ of the speaker. Lateral flow ports and the aerodynamic anti- turbulence control of airflow in the exit duct through a stainless steel foil are managed by precise holes defined from research in the aeronautic field. Overall, this reflex system with its vertical and lateral laminar output, provides the advantage of allowing you to decide whether to place the speakers with the reflex output pointing in or out, depending on room acoustics or personal taste.
SYSTEM 3 way floorstanding, paralaminar “stealth ultraflex” vented loudspeaker.
CABINET Enhanced “Lyre” shape design, progressive thickness triple curvature cabinet walls damped spread resonance spectrum system. Solid walnut vertical clamps.
TWEETER Sonus faber “Arrow Point” DAD (Damped Apex Dome, synthesis of the classic dome and ring transducer) 29XTR2. A Sonus faber designed 29 mm moving coil driver. The ultra dynamic linearity is given by the new Neodymium motor system.
MIDRANGE Sonus faber M8XTR. A Sonus faber designed 80 mm ultra dynamic linearity midwoofer. CCAW wire is used on a controlled “eddy current free” voice coil. The dynamically linear magnetic field motor has a focused field geometry. A special custom diaphragm is made with a blend of traditional cellulose pulp, kapok, kenaf and other natural fibers, developed according to the most natural sound. To further inhibit any residual cone coloration we are using a transparent viscous surface damping coating. A special coaxial anti-compressor is used, designed to remove cavity resonance and distortions.
WOOFERS Sonus faber W15XTR. A totally Sonus faber designed 150 mm ultra dynamic linearity woofer. CCAW wire is used on a composite former “eddy current free” voice coil. The dynamically linear magnetic field motor incorporates triple Goeller rings. A special custom diaphragm is made with a real time air dried non pressed blend of traditional cellulose pulp, kapok, kenaf and other natural fibers, developed according to the most natural sound. To further inhibit any residual cone coloration we are using a transparent viscous surface damping coating.
CROSS-OVER Non-resonant “progressive slope” design, optimized amplitude/phase response for optimal space/time performance. “Paracross topology” on both tweeter hi pass and midrange band pass, cross-over points 250 Hz - 2.500 Hz. Highest quality components are used including Mundorf Evo Oil capacitors and Jantzen inductors.
