Exceptional performance
The Børresen T-series is crafted in Denmark, embodying the expertise gained from our O- and M-series. The T-series is the result of extensive research and innovation, delivering exceptional performance in a refined design. The Børresen T-series has been heavily inspired by the Børresen M-series using downscaled M-technologies.
The patented ironless magnet motor
Børresen IronFree5 driver
Børresen has replaced the conventional iron-core design with four neodymium (N52) rings in a patented mirrored alignment, improving voice coil responsiveness. This speaker features copper pole rings that resist flux changes, enhancing clarity. Since the two magnet pairs in the T-series motor system repel each other with great force that prevents their contact, two non-magnetic copper rings (one external and one internal) are placed between them. The benefits of these in-house cast parts are firstly that they maintain the motor’s cylindrical shape and uniform gap width without any additional profiling components. Secondly, copper is highly efficient in heat dissipation and lastly, it resists the change in the magnetic flux
T series Membrane
The membrane consists of three layers, laminated into a single unit: an aramid honeycomb core between two spread tow carbon fiber skins. The combination of these materials results in a moving surface with exceptional properties. Carbon fiber layers provide optimum stiffness in many different directions. The aramid honeycomb core has an excellent stiffness-to-weight ratio in the vertical direction, while graphene and boron whiskers mixed into the epoxy resin that binds the layers together increase the stiffness of crosslinks between carbon fibers. This in turn makes these bonds stronger, so the entire membrane becomes stronger and less noisy, but remains very light.
Cryogenic Treatment for Enhanced Performance
Cryogenic treatment of copper and silver rings in the T-series loudspeakers, along with internal wiring, baskets, crossover coils and tweeter improve conductivity, strength, and overall performance.
When metal components undergo cryogenic treatment, they are subjected to extreme cooling. In the wake of this process, the crystal structure of such a part contract more and more and alloying elements are being pushed out of it, so that it becomes very similar to a monocrystal. These structural changes of a metal component result in its three highly beneficial new traits. It becomes stronger, its inherent residual stress upon going from the liquid to solid phase during casting is reduced, and its conductivity is increased.
Crossover
Serial configuration, coherent system.
Børresen loudspeakers are fitted with a serial crossover configuration. The reason for this is that the drivers share the very same flow of electric current in the crossover region. As a result, the electric current is phase-locked over the crossover region. Unlike standard parallel filtering, where each driver receives its own frequency and phase content, the new serial filters work by diverting out-of-band currents around the current flows, thus creating a much more coherent system. This unrivaled and innovative technological approach takes your music into a new echelon of acoustic delight.
For the crossover filter, we went to great lengths to source the very best and most sophisticated state-of-the-art components. The coils are foil types wound with paper isolation and impregnated with resin under vacuum to make them mechanically extremely solid and stable.
For crossover capacitors, we use arrays of small military spec stack-foil types. They have the best mechanical stability and lowest induction of any type of capacitor on the market (and they sound wonderful, too).
For tweeter attenuation resistors, we use metal strip types since they have, by far, the lowest noise figures and additionally, a very low thermal variation.
Internal wiring- Ansuz Gold Signature
Ansuz Gold Signature cables feature by far the most innovative and most advanced audio cable technology, literally paving the way to an extremely clear, natural, and authentic sonic reproduction.
Analog dither technology 3rd generation
A 3rd generation of the Ansuz analog dither technology has been developed. Analog dither technology originated in radar, where it ensured a stronger signal and thus greater range. The active Tesla coils send pulsating signals at precisely defined frequencies. These signals are sent in anti-phase. This significantly amplifies the musical signal and eliminates the background noise floor.
Analysis and studies have led to new options – and a lot of listening has resulted in this 3rd generation design which is a further optimization of the most effective frequencies which opens the soundscape even more and with the tiniest details when it comes to reproduction of the recordings.
