Description[edit]
The Cell series from Accuton includes very high quality tweeters, midrange and woofers.
As a special feature, during the development of all drivers, for the first time by a manufacturer, care was taken to ensure that the acoustic centers of all drivers were designed identically. This led to the very unusual construction of bass domes, especially in the woofers. Accordingly, a time coherent reproduction can be achieved despite a straight vertical baffle.
The suggestion for this design came from Michael Weidlich, company Myro, because the cabinet designs of time-corrected loudspeakers can be simplified when using these drivers. The drivers are used accordingly in the Myro Amur Series.
Michael Weidlich about Dirk Vaehsen, developer at Thiel: "I have been listening to him with my requirements for a time/signal correct reproduction. Our ideas in this regard are congruent."
The distortion level of the drivers is also extremely low. The general requirements for a loudspeaker cone are: it should essentially be light, stiff and have high internal damping. Since these requirements contradict each other by design, all conventional diaphragm materials are subject to strong compromise and can be described as unsatisfactory with respect to one or even two of the above requirements. Accuton's special material now makes it possible to meet all three of the above requirements to a large extent. Suitable selection and processing of the aluminium foil enables very thin (up to less than 50 µm) and thus very light moulded parts. The extreme hardness (Mohs hardness 9) of the material results in very dimensionally stable diaphragms whose mass/stiffness ratio is only surpassed by beryllium (highly toxic and not used) and CVD diamond (also used in high quality ACCUTON tweeters and midrange drivers).
The comparatively high internal damping of the ceramic diaphragm is guaranteed by the special production process. As oxidation progresses from both sides towards the center of the material, a boundary surface is formed in the center of the diaphragm. This ultimately consists of two interlocked partial membranes that damp each other. The aforementioned pore formation also leads to the formation of further interfaces across it. This foam-like microstructure has a much better internal damping than, for example, a sintered ceramic part or those countless counterfeits called "ceramic membranes" which merely have a more or less coated surface and essentially retain the properties of the basic material.
