The Børresen Z1 speaker amazes – despite its compact size – with its ability to create a three dimensional soundstage that makes even most subtle musical details become transparent. With its uncompromising musicality and its high-resolution capacity, the Z1 provides an excellent authentic listening experience.

Technologies and Components

Uncompromising performance
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.

The Børresen tweeter

Exceptional efficiency.
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.

Membrane – Bass/midrange

Impressing stiffness to weight ratio.
The Børresen membrane consists of a composite of two layers of very thin carbon on both sides of a 4 mm Nomex honeycomb core. This composite structure – like the one used in formula 1 type of racing cars – provides the ultimate combination of stiffness to weight ratio. The exceptionally low weight of only 5.5 grams allows a very high acceleration factor in the driver, resulting in both outstanding resolution and higher efficiency.

Magnet system – Bass/midrange

Conventional principle, unconventional performance.
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.

Crossover Z-series

Exclusive components and stability.
The Z-series is fitted with a parallel crossover configuration using the same exclusive components from the 0-series. This ensures a very mechanically stable crossover, which minimizes its own resonance.

Ansuz feet

Resonance control option.
The adjustable feet of the ground cross plate are designed to be placed on Darkz resonance control separated by 3 titanium balls. Ansuz Darkz have been designed to ensure a distinctly better mechanical grounding to the floor.
