The principle that guided the development of the Z-series loudspeakers was to provide an uncompromising high-end audio performance with more conventional components than the 0-Series. The technology behind the Z-series consists of electronic components that are either adopted from the 0-series, completely redesigned, or are innovative spin offs resulting from Børresen Acoustics’ extensive audio research activities.
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.
With the invention of the patented iron-free driver system in the 0-series, Børresen Acoustics came to realize that it is possible to reduce induction to an amazing 0.04 mH, which is approximately 10 times lower than that of common driver systems. The challenge for manufacturing the Z-series was to design a new, but less costly driver system with significantly reduced induction. As a result, Børresen Acoustics developed a driver with an 8 mm voice coil and an induction of only 0.06 mH. By linearizing the magnetic field, the driver is less affected by the actual movement and is more easily controlled by the amplifier.
