Børresen 05 Cryo:
The Børresen 05 cryo speaker is the absolute flagship version that delivers peak performance out of Børresen’s audio loudspeaker technology.
Experience the best with Børresen and their multi award-winning 0-series loudspeakers. With their determination and innovation they have set a new standard in high-end audio by designing incredible electronic components, and using unconventional materials along with state-of-the-art manufacturing processes to create excellent sound. Since all of their electronics are built in-house, the highest quality standards are constantly ensured.
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%.
Børresen 05 Cryo Tweeter:
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.
Børresen 05 Cryo Magnet System: Bass midrange
The Børresen 05 magnet motor is a massive improvement from the industry standard and a creative way to stand out from competition. It is uniquely designed without the use of any iron. In the Børresen magnet motor, 4 opposing neodymium ring-magnets are used to squeeze the flux lines together over two solid copper discs, which now act like pole pieces.
The Børresen magnet system has a high flux of 1.1 Tesla. The solid copper pole rings act as very effective heat sinks. This endows the loudspeaker driver with a very high power handling capacity. The copper pole rings also reduce voice-coil inductance to an exceptionally low value of 0.04 MH (less than 10% of regular standard drivers). The extremely low induction provides the driver with some very desirable attributes that enormously elevate the quality of acoustic performance. A much lower induction means a much faster driver, with no lag. This impacts the overall loudspeaker performance which now becomes much more refined and very detailed.
