Myro Digital 1

Description

First active loudspeaker with digital filters from Myro. The model is currently under development. It is intended as a technology study to explore the sonic possibilities of digital filters for pulse-correct loudspeakers. The aim is to find out if the signal / time correct concept of the passive Myro frequency filters can be reproduced with success, if it will end up in a hybrid concept and if a digital solution will sound as dynamic and clear.
The basis is a slim loudspeaker with two bass-midrange drivers in symmetrical arrangement around the tweeter (D'Appolito). Due to the very compact design of the tweeter, the distances between the drivers are very small. This promises an excellent vertical dispersion. The tweeter is not screwed to the cabinet, but held in place by a special clamping device with the aid of a rubber ring. This not only reduces the size, but also reduces the transmission of vibrations to and from the baffle.

Two power amplifiers from Sauermann are used per loudspeaker, which proved to be superior in combination with the Accuton drivers. The electronics are outsourced in the form of a 4-channel power amplifier with digital filters and D/A converter. The control directly with a digital source (e.g. PC) is possible.

The delay compensation of the acoustic centers in the direction of the listening position is done by a digital delay. Corresponding mechanical construction details are not necessary. The Accuton digital module DSP192-4-111 will be used. This module has been specified by Thiel & Partner especially for the Accuton chassis.

The result of the technology study will eventually be incorporated into the concept and further development of the Myro Argun.
