hifiAMT U.Series


Our goal: A ‚reduced to the maximum‘ model range of AMT tweeters which cover all possible applications in home- and studio-audio. The development engineers therefore had the task of keeping the design as simple, straightforward and versatile as possible without compromising the central AMT element -the diaphragm- which determines the tweeter‘s final sound quality. Rather, this should be further optimized based on the experience and knowledge gained from more than 15 years of our diaphragm development.

All of our AMT diaphragms are manufactured in-house by a unique manufacturing process of our own development. The mixture of our basic diaphragm material was optimized with focus on its acoustic properties, hereafter the manufacturing process was tailored to ensure the very best acoustical result possible with every single diaphragm material mix.

Every detail of our diaphragm‘s geometry is based on a deep understanding of the mechanical requirements and physical properties of an AMT diaphragm. Only with this knowledge is it possible to achieve the perfect ratio of a low diaphragm weight, the highest possible diaphragm flexibility, and the most effective inner damping at a maximum of diaphragm stability. Even the slightest shift within this well-balanced ratio would lead to audibly worse results.

This out-balanced ratio makes the Mundorf AMT diaphragm one of its kind. Due to its exceptionally high inner damping, it is characterized by extremely low distortion data. This applies particularly to the odd-numbered harmonic distortions K3 and K5.

Embedded in a well-thought-out, optimized overall concept, this membrane technology can reproduce the highest SPL as well as the finest dynamic nuances with extreme low distortion. So, even at very high volume music performance never gets ‘annoying’.

The relatively heavy weight of the diaphragm and its structural stiffness, together with extra strong magnet systems, lead to a remarkably powerful music reproduction down to its resonance frequency!

In addition to the extremely low K3 / K5 distortion data, this is another unique feature of the Mundorf AMT diaphragms.
The correct interaction of diaphragm and damping of its rear volume was also carefully ascertained. In addition to aesthetic aspects, a simple structure easy to produce serially with utmost precision, and a robust over-all finish were crucial for the final shape of the new AMT U.Series.
