The Børresen T-series loudspeakers, crafted in Denmark, represent the pinnacle of audio engineering, combining the expertise derived from the acclaimed O- and M-series. The T-series stands as a testament to extensive research and innovation, delivering remarkable performance wrapped in a refined design. Heavily influenced by the M-series, the T-series incorporates downscaled M-technologies to achieve its outstanding sound quality.
Børresen IronFree5 Titanium SSE Driver
The Silver Supreme Edition of the T-series features 5-inch drivers that utilize Titanium baskets, offering exceptional structural rigidity and damping properties. Through the application of computer-optimized finite element methods (FEM), Børresen has 3D-optimized the shape of these baskets, ensuring that they do not obstruct airflow from the membrane’s rear strokes, remaining acoustically invisible.
The IronFree8 SSE Driver
The 8-inch Børresen IronFree8 SSE driver is a refined iteration of the driver developed for the Børresen 0-series. Utilizing cryo-treated silver, this driver features a new membrane aligned with the M-series design, employing a spread tow membrane in a sandwich construction without the additional titanium skin layer. This low inductance, iron-free driver enhances lower frequency punch while maintaining the necessary speed to seamlessly integrate with the RP94 Ribbon planar tweeter, allowing for a free-flowing musical experience.
Revolutionary Ironless Magnet Motor
Børresen’s patented iron-free magnetic system has been further refined for the T-series. Unlike conventional drivers, Børresen’s offer approximately ten times lower inductance, with a significant reduction to about twelve times lower than iron-based drivers. By replacing copper pole rings with handcrafted silver rings known for their 6-8% better conductivity Børresen achieves unparalleled performance in sound quality.
Advanced Membrane Construction
The membrane of the T-series loudspeakers consists of three laminated layers: an aramid honeycomb core sandwiched between two spread tow carbon fiber skins. This unique combination results in a lightweight yet exceptionally strong moving surface. The carbon fiber layers provide optimal stiffness in various directions, while the aramid core enhances the stiffness-to-weight ratio. The integration of graphene and boron whiskers in the epoxy resin binding the layers increases the strength of crosslinks between carbon fibers, leading to a quieter and more robust membrane.
Cryogenic Treatment for Enhanced Performance
Cryogenic treatment is employed on the copper and silver rings, internal wiring, baskets, crossover coils, and tweeters of the T-series loudspeakers. This process subjects metal components to extreme cooling, resulting in a denser crystal structure that enhances strength and conductivity while reducing residual stress. The outcome is an improved performance across the board.
Børresen RP94 Ribbon Planar Tweeter
The RP94 Ribbon Planar Tweeter is a marvel of engineering, designed using elaborate finite element methods to optimize the magnetic flux field and ensure high efficiency and outstanding linearity. With an efficiency rating of 94dB, this closed ribbon tweeter operates from approximately 2.5 kHz upwards, boasting an impressively low moving mass of just 0.01 grams. Its rapid response time allows for the revelation of subtle musical details, while its robust construction handles high transient peaks without distortion.
Innovative Crossover Design
The T-series loudspeakers utilize a serial crossover configuration that allows drivers to share the same electric current flow in the crossover region, ensuring phase-locking and creating a more coherent sound. This innovative approach, combined with state-of-the-art components, results in an unparalleled listening experience. Foil-type coils with paper isolation, vacuum-impregnated for stability, and military-spec stack-foil capacitors enhance the overall sound quality.
Bi-Amping Capabilities
The T-series loudspeakers are designed for bi-amping, allowing users to individually power the bass and midrange/treble sections. This setup not only provides sufficient power to each section but also results in cleaner, more precise sound reproduction. The flexibility of both speaker crossover and active crossover bi-amping allows for fine-tuning according to individual listening room acoustics, with Aavik Acoustics’ high-end Analog Active filter providing additional precision.
Advanced Cabinet Design
The T-series cabinets showcase a blend of high-gloss lacquer and real wood veneers, with thick, block-milled hardwood braces and carbon-fiber reinforcements that enhance rigidity and airflow. The rear venting system permits efficient driver decompression, minimizing pressure buildup and distortion, while ensuring a sleek modern aesthetic.
Internal Wiring: Ansuz Gold Signature
Equipped with Ansuz Gold Signature cables, the T-series speakers employ cutting-edge audio cable technology for exceptionally clear and authentic sound reproduction. The Tesla coil principle used in these cables incorporates double inverted coils designed to eliminate noise spikes, significantly enhancing the listening experience.
Active Square Tesla Coils
Active square Tesla coils are embedded in the circuitry boards to further improve noise reduction. Working on the same principle as their passive counterparts, these coils offer superior noise cancellation, enhancing the overall clarity of the audio output.
Third Generation Analog Dither Technology
The T-series utilizes a third-generation version of Ansuz’s analog dither technology, which enhances the musical signal while effectively minimizing background noise. This technology, originally developed for radar applications, amplifies the soundscape, revealing intricate details in music recordings.
