Il Cremonese, the new element of the iconic Homage Collection derives from Lilium. Being true to the highest brand’s tradition and to the history of Italian violin making, with this project Sonus faber pays a tribute to the great master Antonio Stradivari a luthier and artist who revolutionized traditional violin craftsmanship, and continued the work of Andrea Amati to create new concepts of form and finishing still appreciated and cherished world over. This project is a tribute not only to the great violin maker, but also to one of Stradivari’s most famous violins, Il Cremonese, celebrating its 300th anniversary in 2015.

Il Cremonese features the innovative five sides cabinet “Rhomboidal diamond design” which optimizes the structural solidity of the wooden cabinets with a unique diamond shape that is immediately recognizable. Inspired by Lilium, Il Cremonese introduces clean lines and an elegant, minimal, and sharp design. The tilt of the cabinet, its five non-parallel walls structure and the sides applied on the enclosure, increases structural strength of this loudspeaker system.

The solutions adopted eliminate any possible resonance owing to very strong reinforcing structures strategically placed within the enclosure. This new and a typical Sonus faber form is an evolution towards technological and visual innovation, simultaneously maintaining the historic milestones that marked the history of violin making, as well as the history of the Sonus faber brand itself.

To achieve reproduction of the lower frequencies, the Sonus faber SW 22 XT-08 has been developed, a powerful 220 mm infra-woofer. For maximum rigidity, the structure of the cone is made of a lightweight “sandwich” cone structure of syntactic foam and cellulose pulp. This is also implemented in an independent tuned enclosure, acoustically ‘amorphous “stealth reflex” chamber.

Il Cremonese is mechanically decoupled from the floor by a new and innovative version of the patented system “Z.V.T.” (Zero Vibration Transmission). This new implementation of the Z.V.T. presents coaxial spikes metal / elastomer / metal that, compared to the previous version implemented on alternate surfaces, guarantees a further simplification in the construction and aesthetic lightness.

Il Cremonese cabinet inherits its structural concept directly from “the Sonus faber” and, at the same time, it features an innovative five sides cabinet “Rhomboidal diamond design”

The “Stealth Reflex” system derived from the Sonus faber and Aida, and very well known by Sonus faber passionate, is an innovative and patented “para-aperiodic” interpretation of the tuned load. Apart from allowing for a reduction in the dimensions of the cabinet size, it also provides greater extension of the low frequency response and a dramatic containment of every form of distortion; also eliminating spurious ‘port’ noises, typical of traditional reflex systems. Thus, substantially contributing to the correct sound reproduction as well.

3.5 way, full para-aperiodic vented box “Stealth Reflex System, and “Zero Vibration Transmission” technology , vibration transmission- decoupled from the floor, staggered low frequency floorstanding loudspeaker system.

Features “Rhomboidal” diamond design, distributed thickness triple layer cabinet walls, damped with spread resonance spectrum system and harmonic decay internal reflections. The Sub-structural ribs are strategically placed for total rejection of spurious vibrations and standing waves control. Two double “dampshelves” (from “The” experience), i.e. CNC anodized machined avional “vibration dampers” (on top and bottom of each cabinet) “stiffen” the column structures reducing consistently structural micro-vibrations coming from the cabinet’s walls and the transducers. The subwoofer enclosure is integrated to the main enclosure through a new implementation of the Staggered low frequencies emission technology.

Sonus faber “Arrow Point” DAD (Damped Apex Dome, synthesis of the classic dome and ring transducer) H28 XTR-04. A 28 mm moving coil driver by Sonus faber, with Sonus faber’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, a mechanical anti-resonator designed for this application.

Sonus faber M18 XTR-04, a Sonus faber designed 180 mm neodymium magnet system ultra dynamic linearity midrange. CCAW wire is used on a composite former “eddy current free” 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. Like the tweeter, the midrange is also decoupled from the main baffle board and designed synergistically with its optimized “acoustic chamber”. A special coaxial anti-compressor is used, designed to remove cavity resonances and distortions.

Features Non-resonant design, optimized amplitude/phase response for optimal space/time performance. “Paracross topology”. The impedance at low frequencies is controlled in order to obtain a clear and friendly amplifier performance. Double staggered transfer function low frequency/room interface optimized filter. Highest quality is used in terms of the components: last generation Mundorf “Evo” Oil and Silver/Gold/Oil capacitors, Jantzen inductors. Cross-over: 80Hz – 250 Hz – 2500Hz

Sonus faber W18XTR-12, a pair of Sonus faber designed 180 mm lightweight “sandwich” cone structure (high-tech syntactic foam core and two external surface skins of cellulose pulp) woofers are integrated in an acoustically amorphous “stealth reflex” chamber. Designed to blend perfectly with the special midrange and to have absolute definition in their range at the same time: the sandwich structure with outer paper pulp skins has the same sonic character of the midrange cone. A powerful long stroke motor system with a 1.5” controlled “eddy current” voice coil is implemented to obtain high speed, performance and linearity.
