The cryogenic treatment of the speakers’ metal components results in a further significant improvement of conductivity and reduction in inductance. The result is literally opening up a new dimension of musical performance. A sound that is crystal clear, truly natural and utmost refined.
Cryogenic treatment of all metal components of the loudspeaker results in a further significant improvement in conductivity – unleashing finest and most subtle musical details. When metal components undergo cryogenic processing, they are subjected to extreme cooling. In the wake of this process, the crystal structure of the metal contracts more and more. Alloying elements are pushed out of the grain structure of the metal, which now becomes very similar to a monocrystal. These structural changes in the metal have a profound effect on its audio properties, resulting in an increase of conductivity by 6-8%.
All metal components of these speaker series undergo cryogenic treatment. The cryogenic processing cycle requires a 3-day-time window. Within the first 24 hours, the metal undergoes a cooling process from room temperature to cryogenic temperatures. During the second 24 hours, the metal parts are held at temperatures around -196°C (-321°F) before the temperature, within the next 24 hours, returns gradually to room temperature. The gradual cooling and heating is critical to avoid any thermal stress. The process strengthens and compresses the grain structure of the metal components and reduces inherent residual stress that occurs when metal solidifies from its liquid phase to a solid phase.
Elaborate finite element methods have been applied to linearize and optimize the magnetic flux field, to facilitate driver movement and to ensure high efficiency and outstanding linearity.
The efficiency of this closed ribbon tweeter amounts to an exceptional 94dB and operates from approximately 2.5 kHz upwards. The moving mass is extremely low at 0.01 grams. The totally concealed tweeter has the capacity to operate at an incredible speed, which is an absolute prerequisite to unlocking the most subtle and refined sound details of any kind of music. The enormous robustness of this tweeter allows it to handle extremely high transient peaks without any ear fatiguing breakups. No transformers are being used.
