Power and grace. Dynamic and melody. Fullness and void. Kindness and impetuosity. Harmony and chaos. Seemingly opposite strong contrasts that co- exist in the music. Lilium has been designed to shape those great contrasts expressed by music. It is the will of synthesis of two opposite elements: two separate identities that, although working independently one from each other, cooperate inside the same shape. The creation of a shape that holds two distinct elements has been a big challenge from a technical point of view and from a design one as well. Everything was basically about the need find a new way to put together the large volume required to reproduce the very low frequencies, with the structure dedicated to the reproduction of the main portion of the audible spectrum. The marked separation between these two elements is made visually clear by the use of different materials: finely wrought walnut wood for the front part and a definitely softer material – leather – for the rear enclosure. We have decided to adopt the organic style of the natural shapes, which is the family the Lilium belongs to. Undoubtedly, this result marks a further step forward in the stylistic and acoustic research by Sonus faber.


"Lyra Shape" design

progressive thickness triple curvature cabinet walls damped spread resonance spectrum system, Sub–structural ribs are strategically placed for total rejection of spurious vibrations and standing waves control.


Infra Woofer

Sonus faber SW26 XT-08 woofer.  Sonus faber designed a 260 mm infra woofer, lightweight hard paper composite sandwich cone  technology for a maximum rigidity and implemented it in an acoustically amorphous passive radiator tuned separated enclosure.



Non-resonant design, optimized amplitude/phase response for optimal space/time performance. “Paracross topology”. The impedance at low frequencies is controlled for a clear and friendly amplifier performance.



Sonus faber “Arrow Point” DAD (Damped Apex Dome, synthesis of the classic dome and ring transducer) H28 XTR-04. A Sonus faber designed 28 mm moving coil driver, with Sonus faber’s vibration optimized mechanical interface.



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.




Sonus faber W18XTR-16. A triple 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.
