BØRRESEN Cryo Edition:

The Cryogenic treatment of the speakers’ metal components results in a significant improvement of conductivity – unleashing finest and most subtle musical details.

The metal components of the loudspeakers are subjected to a Cryogenic processing. The Cryogenic processing cycle requires a 3-day-time window. Within the first 24 hours, the metal is subjected to a cooling process from room temperature to Cryogenic temperatures. For the second 24 hours, the metal components are then held at temperatures around -196°C (-321°F) before the temperature, within the next 24 hours, returns gradually to room temperature. The gradual cooling down and heating up period is critical to avoid any thermal stress.

The process will strengthen and enhance the grain structure of the metal components and reduce inherent residual stress that is created when metal solidifies from its liquid phase into a solid phase.

The result is literally opening up a new dimension of musical performance. A sound that is crystal clear, truly natural and utmost refined.
