Myro Concert Series

Description[edit]

The Concert Series models differ from other Myro developments in that they were not primarily designed for home use, but for stage and sound reinforcement applications. However, the same design specifications and background for period-correct loudspeakers presented in the Myroklopedia also apply to them. This was a continuation of Myro's activity in PA technology, which already took place in the 1990s with an active coaxial monitor with analog computer.
The highest amplitudes in music are found in transients. Asynchronous, out-of-phase loudspeaker transients destroy transient reproduction. This is a considerable compression of the impulse dynamics! This is why most sound reinforcement loudspeakers need relatively much amplifier power for music reproduction, despite the high efficiency (measured in steady state), "time correct" in relation to the efficiency (measured in steady state) relatively little. This is because the energy yield in terms of amplitude height during transients is significantly higher.

Nevertheless, the models Myro Concert, Myro Grand Concert and Myro Concert Monitor are also suitable for use in living rooms, while the Myro Floor Monitor is not suitable for home use because of its special application.
All models are based on the legendary Air Motion Transformer ESS Heil AMT 1 and other chassis from Seas. They are thus constructively similar to the models ESS AMT 1 Tower and ESS Connoisseur Series AMT 450, which had previously also been produced by Myro on behalf of [Audio Int'l], Frankfurt, and served as the model for the Myro models. The Concert Series had already been preceded by the technically related Myro Heaven's Gate. Also derived from the Concert Series is the Myro Pro Fidelity 3.1, intended for home cinema use, with identical equipment and similar construction.

The models are designed as dipoles, in that the AMT also radiates to the rear, where the sound is diffusely dispersed via a wedge. For this purpose, the cabinet contains an opening on the side for the sound outlet. In the area of the tweeter all cabinets have a special rounding at the front. It complements the horn shape of the ESS AMT 1 and results in a significantly more linear frequency response.
Due to problems with the supplier ESS the models had to be discontinued. The ESS Heil AMT 1 can perhaps still be used in pairs, but for a series the necessary series consistency is missing.
The Myro Grand Concert II formed the transition to the subsequent models of the "Mundorf" Series.
