Statement 2.5-Way Floor Standing Speaker
The BØRRESEN 02 speaker is a premium 2.5-way speaker that has re-defined what is possible to achieve with a compact floor standing design. Its unique ribbon tweeter and the innovative membrane of the low-weight bass/mid-range driver reproduces the tonality of the individual timbre of any instrument as well as the vocal range of a singer with an unprecedented authenticity that imbues any music with a captivating quality.
The unique technologies implemented in the 02 result in a new paradigm in the expression of detail & information. There’s scale, tonal realism and a sense of effortlessness with this speaker that is often described by discerning audiophiles as ‘perfect’. The 02 plays music with a rare refinement & natural musicality. A clear and undistorted dynamic sonic performance reaching from the upper pitches to the lower bass notes with cohesion and energy.
The cabinet is carefully designed by BØRRESEN and built by Italian artisans to coach-building levels of quality. 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 02 represents the pinnacle of compact floor standing speaker design.
The BØRRESEN planar ribbon tweeter is an entirely new technical development. Elaborate finite element methods have been applied to linearise and optimise 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 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 (similar to the one used in Formula 1 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.
Bass/midrange – The Iron-Free Revolution
The patented BØRRESEN magnet system is breaking new ground. Its 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 motor is breaking new ground here. It is uniquely designed without the use of any iron. 4 opposing neodymium ring-magnets are used to squeeze the flux lines together over two solid copper discs, which now act like pole pieces.
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). The extremely low induction provides the driver with some very desirable attributes that elevate the quality of acoustic performance enormously. A much lower induction means a much faster driver with no lag. This impacts the overall loudspeaker performance which now becomes much more refined and very detailed. Lower induction also causes less resonance impedance variation, which means less phase angles and less impedance variation for the driving amplifier. Lower induction will also curb the impedance rise over system resonances. In terms of musicality, this will result in bass that is less ‘boomy’ but much more pristine. Bass performance becomes very tight, well-focused and more real-world.
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, BØRRESEN 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, BØRRESEN 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, BØRRESEN use metal strip types since they have the lowest noise figures (by far) and a very low thermal variation.
The cabinets are heavily braced, block milled, compressed wood structures, beautifully veneered in walnut and fitted with solid walnut inserts. They follow the best of Danish furniture design traditions paired with the stylish shapes that were initially created by the late Franco Serblin from Sonus Faber. The tweeter section is vented to balance out the build-up of air pressure. The bass sections consist of tuned ports calibrated for musically relevant frequencies.
Ansuz Darkz decouplers have been designed to ensure a distinctly better mechanical grounding of the speaker cabinet to the stand and/or to the floor. Ansuz Darkz consist of 3 discs separated by 3 titanium ball bearings. Ansuz Darkz are available in 4 alloys that allow for different sonic levels of grounding qualities.
Versions and Pricing
The 02 comes in three versions – Standard, Cryo and the Silver Supreme Edition (listed separately)
The standard version is AUD 72,900 and the Cryo version is AUD 79,500.
The Cryogenic treatment of the speakers’ metal components results in a further improvement of conductivity, unleashing finest and most subtle musical details. When metal components undergo cryogenic processing, they are subjected to extreme cooling. In the wake of this process, the crystal structure of the metal contracts more and more. Alloying elements are pushed out of the grain structure of the metal, which now becomes very similar to a monocrystal. These structural changes in the metal have a profound effect on its audio properties, resulting in an increase of conductivity. The result is literally opening up a new dimension of musical performance – a sound that is crystal clear, truly natural and extremely refined.
