The speaker system uses drivers that have been developed specifically for this series. The 28mm (1.1in) tweeter features DAD™ Damped Apex Dome technology, the same as in the Reference collection, and features a silk dome with a tricycle damper mount, reminiscent of its unique predecessors.
For RF transmission, a 28 mm tweeter with a silk dome membrane, a neodymium magnet and Damped Apex Dome (DAD) technology is used, which makes it possible to reduce the parasitic resonance of the dome to zero by using a special damper mounted on the aluminum arc of the divider installed in front of it.
The model uses the famous D.A.D. (Damped Apex Dome) high–frequency driver - the same one used in the Sonetto series, with a 29mm diaphragm from Kurtmueller made of soft silk, made by hand.
The Sonus Faber Lumina II is equipped with a 150 mm mid-low frequency driver with a cellulose diffuser with natural fibers. With a crossover frequency of 1,800 Hz, the Lumina II performs in the range of 55-24,000 Hz.
The floorstanding loudspeaker has a two-band configuration, and a tweeter with a 28 mm DAD dome (Damped Apex Dome) is responsible for high frequencies, loaded onto a maze made of solid wood. The main driver reproducing midrange and bass is the MW 18XTR-04 with an 18 mm diffuser made of cellulose and natural fibers.
