Experience the ultimate in loudspeaker performance with the Børresen M6 Floorstanders. This flagship pair (black/white high-gloss, Darkz Z2S stands) offers breathtaking dynamics, holographic imaging, and an uncompromised musical journey.
This ambitious no-compromise Børresen M2 tells the story about the challenges we conquered, and how our technologies were turned upside-down and scrutinized one by one, to eventually make room for one more variant in our very best speaker range thus far. The Børresen M2 speaker is fit to handle even the most demanding music gracefully and with ease. Designed with a dual purpose: to visually blend into any decor and acoustically integrate therein to provide the best performance.
Zirconium, topology-optimized
This basket is a real revolution – it is a topology-optimized basket made of zirconium, which ensures maximum rigidity and thus minimum vibration and resonance. Zirconium is by far the best choice of material, since it allows the basket to generate an inconceivable quality of natural sound.
This basket is not just a placeholder for the membrane. The energy generated by the membrane is also held by the structure behind it. The goal was therefore to eliminate the noise of the basket by designing a basket with maximum stiffness. Studies were conducted using computer-optimized finite element designs, resulting in a topology-optimized basket made of the exclusive material zirconium.
Børresen has not only designed a basket with extreme stiffness, but also added important factors such as tremendous internal damping and resonance control, resulting in extreme clarity in overall performance.
Børresen IronFree5 Zirconium SSE driver
The membrane is designed to achieve maximum stiffness with minimum noise. The membrane for the M-Series speakers are the most advanced and sophisticated speaker membrane on the market. The membrane has the highest stiffness and the lowest membrane resonance. The technological requirements for this unrivalled, world-class membrane performance made it necessary to design, develop and assemble all components in-house. Michael Børresen and his team had to construct a large number of different variants and models until they accomplished their uncompromising goal of ultimate membrane performance for an unprecedented sound quality.
The result is a membrane that consists of four skins laminated into a single unit: two layers of spread tow carbon fiber, a layer of aramid honeycomb spacers in between, and a titanium skin with Ansuz Supreme coating.
The combination of all these materials give this state-of-the- art membrane its unique properties. Spread tow carbon fiber is designed to ensure a skin with optimum stiffness in many different directions. This unique characteristic reduces sound disturbing vibrations and resonances to an unprecedentedly low level. This is also true for resonances in the frequency range above 8 kHz. Since the membrane/driver is used up to the 2.5 kHz range, disturbing resonances have been shifted two octaves outside the effective frequency range, ensuring an absolute minimum of resonances.
The aramid honeycomb also has the best stiffness to weight ratio in the vertical direction.
Titanium has perfect resonance control properties and supports a natural, organic sound of the membrane. With the Ansuz Supreme coating, the skin of the membrane is further acoustically optimized. This coating is applied to the titanium skin in a Hi-PIMS (High Power Impulse Magnetron Sputtering) machine to create the finest and most uniform layer of zirconium, followed by a layer of tungsten and finished with a layer of aluminum chrome nitride. This coating provides the music with a truly impeccable sound quality.
Børresen IronFree5 Zirconium SSE driver
The patented Børresen iron-free magnetic system has been further refined, and is used in all loudspeakers in the M-series. Their inductance is about ten times lower than that of conventional drivers. This exceptionally low inductance has now been even further reduced to an unprecedented new minimum level – about 12 times lower than the inductance level of conventional, iron-based drivers. Here is how we achieved this: Since silver has 6-8% better conductivity than copper, we replaced the copper pole rings with in-house manufactured, handcrafted silver rings.
Extreme treatment, huge improvement.
Cryogenic treatment of all metal components of the loudspeaker results in a further significant improvement in conductivity – unleashing the 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 by 6-8%.
All metal components in the M-series undergo cryogenic treatment. The cryogenic processing cycle requires a 3-day-time window. Within the first 24 hours, the metal undergoes a cooling process from room temperature to cryogenic temperatures. During the second 24 hours, the metal parts are held at temperatures around -196°C (-321°F) before the temperature, within the next 24 hours, returns gradually to room temperature. The gradual cooling and heating is critical to avoid any thermal stress. The process strengthens and compresses the grain structure of the metal components and reduces inherent residual stress that occurs when metal solidifies from its liquid phase to a solid phase.
Børresen RP94 Ribbon Planar Tweeter
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.
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.
The Børresen M-Series loudspeakers are an impressive example of Audio Group Denmark’s commitment to creating aesthetic design that enhances musical performance. A distinctive feature of the cabinet design is the recess on the back, which has a curved shape. This design element is inspired by the Børresen speaker stand and adds an additional touch of sophistication to the overall aesthetic of the speaker.
The base of the speaker has been specially prepared for Ansuz Darkz, a technology that helps to better control resonance. This attention to detail not only improves the speaker’s sound quality, but also adds to its visual appeal.
Overall, the M-Series speakers are the perfect blend of form and function, which reflects the excellent and highly productive partnership between two great minds in the audio industry – Michael Børresen and Flemming Erik Rasmussen. The sleek and elegant design of these speakers, combined with their outstanding audio performance, make them a testament to Audio Group Denmark’s commitment to audio excellence.
Special designed bass/midrange driver ventilation thatprovideslow compression insuring fast and agile speaker driver. Furthermore it is designed with bass reflex sections for bass drivers, leading to a dynamic and harmonious balance between midrange and bass.
The M2 is equipped with 3 unique 5″ M-series speaker drivers – one bass midrange/driver and two bass drivers that are connected in pairs so that they act as one bass speaker driver. This approach ultimately results in increased speed, precision, and depth, which enriches the speaker with much more musicality.
With bi-amping you are able to individually feed the bass section and the bass/midrange section which includes the treble. This not only provides sufficient power to each section, but also results in a cleaner, more precise sound.
This loudspeaker is designed with two types of bi-amping in mind. The first is speaker crossover bi-amping. The frequency between the bass section and the midrange/treble section is optimized, so that it provides best performance.
The second option is active crossover bi-amping, where you can adjust the crossover frequency yourself. This type of crossover is the optimal solution for fine-tuning your speakers according to your listening room’s acoustical properties, allowing you to control the amount of bass and the balance between the bass and midrange/treble. To further enhance your listening experience, Børresen’s sister company, Aavik Acoustics, has developed a high-end Analog Active filter that works seamlessly with these new speaker models, providing the ultimate in precision and clarity. The Aavik active crossover is found in a variety of Aavik amplifiers.
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.
The principle is to have two coils that are wounded in each direction / a coil and a counter coil. In Ansuz words: “A double inverted coil” – the two coils are both carrying voltage – and when the Tesla coil encounters a voltage spike a counter spike is activated in order to eliminate the noise. As Noise spikes are pure voltage and carries virtually no charge, the cancelation is quite good, but not 100%. By adding more P-TC coils in parallel the performance increases. By implementing this the perceived blackness in the music improves significantly. Ansuz Tesla coils are available in various types as they complement each other in terms of strengths /weaknesses.
Impressive noise reduction.
The active square Tesla coils are embedded in our circuitry boards – one coil on the top and the counter coil on the rear side. The principle is exactly the same as the active Tesla coil and thus a great ability to eliminate noise than the passive Tesla coils.
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.
Prevents airborne noise.
All cables and cable screens are acting like antennas for airborne RF noise which of course is a huge problem. The passive cable Tesla coil is wounded on the external part of the cable and protects the signal from absorbing the airborne RF noise. This noise is absorbed in the Tesla coil.
As there is a voltage running in the conductor itself, and it is wounded in the counter direction – this is used as the counter coil and the RF noise is then eliminated.
The M6 features 6 unique 5″ M-series speaker drivers. These drivers are connected in series so that two units work together as bass/midrange drivers and the other 4 units work together as bass speaker drivers. This approach ultimately results in increased speed, precision, and depth, which enriches the speaker with much more musicality.
