The huge wealth of knowledge gained through the ambitious â€The Sonus faberâ€™ project in terms of research and development in innovative and extraordinary technical and functional solutions has brought us to a new and very exciting project. A speaker as grandiose as an opera by Giuseppe Verdi, able to revolutionise, and at the same time express, the essence of Sonus faber values. A speaker born from the heart of the Team, able to reveal how much Sonus Faber has evolved and yet maintaining its original spirit and combining â€traditionâ€™ with â€technological innovationâ€™. SYSTEM 3.5 way, Sound field Shaper Technology, â€śZero Vibration Transmissionâ€ť technology, para-aperiodic vented box â€śStealth Reflex Systemâ€ť, staggered low frequency floorstanding loudspeaker system. CABINETÂ â€śLyra shapeâ€ť design, dual side curvature, special cross grained okoumĂ¨ plywood, used in a double thickness constriction layer damped configuration. Subâ€“structural ribs are strategically placed for total rejection of spurious vibrations and standing waves control. Two â€śdampshelvesâ€ť (from â€śTheâ€ť experience), i.e. CNC anodized machined avional â€śvibration dampersâ€ť (on the top and on the bottom of the cabinet) â€śstiffenâ€ť the column structure reducing consistently structural micro-vibrations coming from the cabinet walls and the transducers.Â The â€śAnima legataâ€ť system is used in an innovative way, encompassing the 3 inner chambers of the front firing drive units. A special steel rod, a high speed mechanical interface, concentrates the remaining micro-vibrations conveying them to the dual multiple â€śTuned Mass Dampersâ€ť, i.e. two differently tuned special custom devices optimized to erase micro-vibrations, by oscillating in anti-phase. A totally new floating bridge â€śBow springâ€ť suspension for vibrational interface has been 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 room. TWEETER Sonus faber â€śArrow Pointâ€ť DAD (Damped Apex Dome, synthesis of the classic dome and ring transducer) 29 XTR-06. A Sonus faber designed 29 mm moving coil driver, with Sonus faberâ€™s vibration optimized mechanical interface. The ultra dynamic linearity is given by the new Neodymium motor system. Implemented with a natural wood acoustic labyrinth rear chamber,Â a mechanical anti-resonator designed for this application. To perfectly match the high frequency performance to different listening rooms and different tastes it is possible to adjust the SPL of the tweeter. MIDRANGE Sonus faber M18 XTR-08. A Sonus faber designed 180 mm neodymium magnet system ultra dynamic linearity midrange. CCAW wire is used on a composite former â€śeddy current freeâ€ť voice coil. The dynamically linear magnetic field motor incorporates triple Kellog/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. 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 the two different materials, Avional and Gunmetal, allows eliminating any mutual resonance. The same way as the tweeter, the midrange is decoupled from the main baffle board and designed synergistically with its optimized â€śacoustic chamberâ€ť. A special coaxial anti-compressor is used, designed to remove cavity resonances and distortions. WOOFERS Sonus faber W22 XTR-12. A pair of Sonus faber designed 220 mm lightweight â€śsandwichâ€ť cone structure (high-tech syntactic foam core and two external surface skins of coated cellulose pulp) woofers are embebed in an acoustically amorphous â€śstealth reflexâ€ť chamber. 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 2â€ť controlled â€śeddy currentâ€ť voice coil is implemented for high speed, performance and linearity. Special coaxial anti-compressor are used, designed to remove cavity resonance and distortions. INFRA WOOFER Sonus faber SW32 XT-08.Â Sonus faber designed a 320 mm infra woofer, lightweight honeycomb composite sandwich cone structure with Nanocarbon technology for a maximum rigidity and implemented it in an acoustically amorphous â€śstealth reflexâ€ť chamber. The unit features a very powerful long throw motor with a 3â€ť voice coil for ultra dynamic linearity. To perfectly match the low-end performance to different listening rooms it is possible to adapt the SPL of the infra woofer. SOUND FIELD SHAPERÂ The special patented Sound field Shaper technology,Â a direct derivation from the â€śTheâ€ť, allows the control of the direct/reverberant radiation ratio of the Aida. The sound field shaping module can be SPLÂ optimized. SOUND FIELD SHAPER TWEETER 29 mm ultra dynamic linearity neodymium dome driver. Optimized off-axis radiation for this special application. SOUND FIELD SHAPER MIDRANGE 120 mm, paper pulp/natural fiber blend cone driver for maximum coherence with the front midrange emission. CROSS-OVERÂ Non-resonant design, optimized amplitude/phase response for optimal space/time performance. â€śParacross topologyâ€ť on the tweeter hi-pass. The impedance at low frequencies is controlled for a clear and friendly amplifier performance. Triple staggered transfer function low frequency/room interface optimized filter. Highest quality is used in terms of the components: Mundorf â€śSupremeâ€ť Silver/Gold/Oil capacitors, Jantzen inductors. Cross-over: 55Hz - 180 Hz - 250 Hz - 3000Hz. FREQUENCY RESPONSE 20 Hz â€“ 35.000 Hz, Stealth reflex included. SENSITIVITY 92 db SPL (2.83V/1 m). NOMINAL IMPEDANCE 4 ohm. POWER HANDLING 100W â€“ 1KW, without clipping. DIMENSIONS 1725mm x 482mm x 780mm (HxWxD). WEIGHT 330 Kg per pair â€“ net weight 550 Kg per pair - shipping weight (The shipping weight may slightly change from time to time because different humidity values over the year might affect the wooden boxesâ€™weight).
