ESB Audio 10.6K3 speakers

ESB Audio 10.6K3 3-way component speakers

Diecimila, super high-end handcrafted component speakers that represent the highest level of technological development and innovation today. The top-of-the-line 10000 series has been designed without regard to any economic, structural or technological limitations in order to achieve absolute sonic clarity in music reproduction. ESB Audio's research and development laboratory was given full control over all speaker functions and parameters, allowing these superb products to be produced without the typical compromises many high-end speaker manufacturers have to make. Exclusive materials with uncompromising properties were used in the production to achieve a single goal. And there was nothing more modest than the creation of a perfect three-band system that will allow the listener absolute sound quality without any limits. Introducing the ESB Audio Diecimila, speakers that were made for the love of sound clarity, music and art.

ESB Audio 10.TB - super high-end beryllium tweeter

Advances in the development of beryllium processing technology, intensive study of the geometric shape of the special large diaphragm, which also includes a one-piece suspension, and the innovative MT-1 ESB motor system led to the development of these audiophile speakers. The ESB Audio 10.TB is a tweeter with significantly wider range, lower distortion, better performance and higher efficiency than any other available tweeter on the market today. A huge and high-quality neodymium magnet has been combined with polar parts made of material with very high magnetic permeability. This creates a field of unique magnetic flux, perfectly linear and symmetrical. This means that the fine tweeter coil will always have the same magnetic field strength at any point in its path, greatly reducing distortion and increasing the ability to reproduce the lowest frequencies in the tweeter range. All components of the tweeter have been manufactured using sophisticated precision control machines to ensure assembly precision and thus centering between voice coil and magnet with unimaginable tolerance compared to other tweeters. The result can be called absolute precision, which is not possible with any tweeter whose production uses plastic parts. Careful study was also devoted to the development of the central part of the engine assembly, where an innovative design was able to eliminate any phenomenon of air compression under a very thin beryllium membrane. This arrangement prevents any deformation of the diaphragm with the obvious advantages of less distortion. In order to dampen the rear acoustic waves generated by the tweeter membrane, a carbon lower part was designed, the special exponential shape of which cancels these waves and the work is subsequently completed by a special acoustic absorbing material.

ESB Audio 10.W - super high-end bass speaker

The woofer diaphragm is the very first in the world to use a double carbon fiber shell made of pure carbon nanotubes. The choice of a double shell crossed at an angle of 45° allows the distribution of stress along the axis of the nanotubes, thanks to which it was possible to produce an extremely light membrane with stiffness and non-deformability, which has never been achieved in the history of any loudspeaker. The hemispherical membrane is completely made of one piece, even without the use of a classic dust cover. This method, combined with gluing the suspension to the rear face and extending the diaphragm well beyond the point of connection with the suspension, allows to avoid the classic discontinuities that exist in any other woofer and ensures a completely neutral and faithful reproduction of the sound. The stiffness of the diaphragm, which is much higher than that of many metals, in combination with excellent internal damping, guarantees a perfect "piston" effect where the performance does not change with frequency and minimizes deformations caused by internal vibrations. The playback speed during transients is astounding and hard to match. The carbon ring connects the moving coil to the diaphragm and its special shape ensures a large contact area on both the coil side and the diaphragm side. This guarantees a perfect transfer of energy from the coil to the membrane without losses and above all without concentration of effort. Normally this important contact point, where all the energy released by the voice coil goes into the diaphragm, is made with a simple glued ring. This does not guarantee constant reproducibility with precision, but above all, due to its small size, it concentrates all the effort on a small area, which causes stress on the parts and this results in distortion and distortion of the sound. Resonances in the body of a musical instrument are an essential part of defining its nature and quality. However, the opposite is true for the speaker. Speaker basket resonances are a significant cause of sound timbre. ESB's R&D department devoted much of its time to developing materials that would balance the weight, stiffness and cushioning of the ideal basket. The final result was created from a mixture of aluminum and carbon fiber. Although aluminum has extreme stiffness, it also has one negative property, which is that it is not particularly damped. That's why at ESB they combined high-quality aluminum used in the aviation industry (Avional) with carbon fibers and high thickness, which makes the basket practically inert. It has no discernible timbre, which allows the speakers to work with maximum clarity and dynamics. Although very expensive to implement, the use of aluminum in ESB loudspeakers plays a vital role in the company's philosophy.

A look inside the bass speaker ESB Audio 10.W

An important component of practically all loudspeakers is the magnet. Featuring a large titanium voice coil and neodymium magnet, the MW-1's robust motor reduces distortion levels to a fraction of those found in even the best alternative speakers available on the market today. The copper sleeve encapsulates the entire distance of the voice coil, reducing its inductance to about 1/10 of its original value. This feature substantially reduces the driver's nonlinearity and intermodulation distortion by increasing its ability to handle overload. In the development of the 10000 series loudspeakers, great effort was made to minimize eddy currents in the iron parts of the engine and suspension system. Eddy currents are created by the movement of the coil and produce a chaotic magnetic field that acts "against" the fixed magnetic field, causing deformations. The best way to reduce these currents is to saturate the metal parts of the motor as much as possible. When the metal around the coil is completely saturated, induced bending, i.e. eddy currents, cannot develop. This requires very advanced design studies, precision machining of parts and huge magnets. Now let's take a closer look at another important feature, which is speaker cooling. The ventilation hole in the middle part of the magnet ensures both the correct exchange of heat between the coil and the outside air, as well as a reduction of the pressure under the woofer membrane. Although it looks simple, this opening required a lot of aerodynamics to create its ideal double opposite cone shape, which would allow the reduction of turbulence that could cause unwanted noise. In addition to this, a flow laminator has been inserted inside to further reduce turbulence by balancing the currents in an orderly and non-random manner.

ESB Audio 10.M - super high-end center speaker

All that remains is for us to share the details of the last piece of the puzzle of this top-of-the-range ESB Diecimila speaker system, which is the center speaker. Due to the much lower stress on the diaphragm than in the bass speaker, ESB decided on a more classic choice of material for the diaphragm of this speaker. The chosen material is "paper", which is even more suitable for medium and high frequencies. We deliberately put the paper in quotation marks, because in our presentation it is of course not a classic paper. It is a mix of nanocrystals of cellulose pulp used as a binder with the addition of spruce fiber from the Dolomites. This is the same type of wood used in making Stradivari violins and is called "soundwood". Added to this is a percentage of jute and sisal fiber, as both of these materials offer compact and very long fibers that are perfectly suited for producing a sound-perfect membrane. A surface layer of phenolic resin is spread on both sides of the membrane, which perfectly aligns it and increases its rigidity with a negligible increase in weight. In addition, this transformation makes the material practically insensitive to moisture. Cellulose nanocrystals used as a binder have a ratio of stress and deformation caused by it (Modulus of elasticity in tension, or Young's modulus) even higher than aluminum and other metals, but with much higher internal damping. However, the extra weight is only a small percentage of the weight of the metal, in short, it is an ideal mix of lightness, stiffness and damping, all for maximum natural reproduction. The basket of the ESB Audio 10.M center speaker uses the same type of technology as the woofer with a mixture of aluminum (Avional) and carbon fiber, which allows the speakers to work with maximum clarity and dynamics. Although expensive to implement, the use of aluminum in the speakers plays a vital role in our design philosophy. The 10.M also implements a radial voice coil ventilation system. Even the cooling of the speaker remains the same. The ventilation hole in the middle part of the magnet ensures both the correct exchange of heat between the coil and the outside air, as well as a reduction of the pressure under the woofer membrane.

About the ESB Audio brand

The history of ESB Audio dates back to 1972, when this Italian brand was officially founded. ESB audio is one of the most famous speaker system manufacturers of the second half of the 19th century, and during their rich history they have launched many innovative technologies and many high-end home audio products that have achieved huge worldwide success. Based on the experience gained, in 1984, ESB engineers began to engage in research aimed at optimizing sound in the automotive environment, and two years later they started the production of the first car speakers. Thanks to the great success, ESB began to focus more and more on the automotive industry and its demanding challenges. Car Audio is becoming a phenomenon of the time, and in 2005 a school focused exclusively on vehicle sound was founded in the city of Aprilia, where ESB is based. It was then that the final decision was made to leave the world of home audio and focus exclusively on vehicle sound systems. Currently, ESB belongs to the Italian company Apex Group together with the American manufacturer of audiophile amplifiers and DSP processors Zapco. In the offer you will find several model lines of speakers, led by the super high-end Diecimila three-way system, which represents probably the best quality and most expensive car speakers on the market today. And that is the main mission of ESB audio. To produce speakers of the highest quality, focused on faithful sound, which will allow the user to reproduce as the interpreter intended. Exactly according to the company's slogan "Just like live".
