BØRRESEN is presenting new editions to their existing 0-series and Z-series. “In the unwavering quest to strive for the ultimate authenticity in audio performance, BØRRESEN Acoustics have always been willing to break new ground. This implies the use of unconventional materials, the design of brand-new components and the application of state-of-the-art processes in manufacturing. Based on this approach, BØRRESEN now pre- sent their new premium models of loudspeakers that complete their O-series and Z-series. The sound quality of these premium models evokes new superlatives for authenticity, clarity and refinement of musical performance.”


The BØRRESEN Silver Supreme loudspeakers represent the absolute flagship version among the BØRRESEN loud- speakers.

The patented BØRRESEN magnet motor has been further refined. Since silver has turned out to have the highest spe- cific electrical conductivity of all metals, we replaced the copper pole rings by in-house manufactured, hand-crafted silver rings. As a result, induction could be reduced to a stunning, so far unprecedentedly low level.

To take full advantage of all the performance-enhancing au- dio properties of the new Silver Supreme O-series, all other metal components of these premium speakers also under- go cryogenic treatment.

The result is absolute musical purity. With their unadulter- ated authenticity of musical reproduction, these premium loudspeakers set a new and unsurpassed standard – clarity, refinement and sound-staging at its very best.


Cryogenic treatment of all metal components of the loud- speaker 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.

All metal components of these speaker series undergo cryogenic treatment. The cryogenic processing cycle re- quires a 3-day-time window. Within the first 24 hours, the metal undergoes a cooling process from room temperatu- re 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 result is literally opening up a new dimension of musical performance. A sound that is crystal clear, truly natural and utmost refined.
