Borresen 03 Silver Supreme Loudspeaker

The Børresen 03 Silver Supreme Edition speaker is equipped with enormous driver power and dynamics. The speaker resolves even the most fragile details from any audio source. The driving power in the lower bass segment, along with an easygoing punch, provide a unique sound stage liveliness. (pre-order)

The Børresen Silver Supreme Edition loudspeakers are the absolute flagship versions among the Børresen loudspeakers. By replacing the copper pole rings by in-house manufactured, hand-crafted silver rings the inductance is reduced substantially. Additionally, all metal components, are subjected to a cryogenic treatment. These loudspeakers set a new and unsurpassed benchmark. Clarity, refinement and sound staging at its very best.

The patented Børresen iron-free magnetic system has been further refined. Børresen uses iron-free drivers in all its loudspeakers. Their inductance is about ten times lower than that of conventional drivers. This exceptionally low inductance has now been even further reduced to an unprecedented new minimum level – about 12 times lower than the inductance level of conventional, iron-based drivers. Here is how we achieved this: Since silver has 6-8% better conductivity than copper, we replaced the copper pole rings with in-house manufactured, handcrafted silver rings.

To take full advantage of all the performance-enhancing audio properties of the Silver Supreme 0-series, all other metal components of these premium speakers also undergo cryogenic treatment. This reduces their inductance by another 6-8%.
The result is absolute musical purity. With their unadulterated 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 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.
