Borresen Acoustics 01 D-TC Loudspeaker with stand
The BØRRESEN 01 speaker, with its unique ribbon tweeter and the innovative membrane of the low-weight bass/mid-range driver, guarantees a transparent and authentic musical performance projected onto a live stage. The artistic design of the cabinet and the stand turn this loudspeaker into a perfect amalgamation of outstanding musicality shaped into a piece of art.
The BØRRESEN planar ribbon tweeter is an entirely new technical development. 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.
The BØRRESEN magnet system* is breaking new ground. It's unique, innovative and unprecedented technological design makes it stand out from anything else on the loudspeaker market.
Since the invention of the loudspeaker driver, the fundamental structure of magnet systems has not changed. Iron has been used to concentrate the magnetic flux in a narrow gap where the voice-coil is located. Iron is suited for the concentration of flux, but also poses some challenging issues when it comes to the voice-coil parameters. These parameters also change with the position of the voice-coil, creating considerable iron distortion.
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).
