The main loudspeaker (the front loudspeakers) of the main unit only receives the southern part of the seed spectrum, while the entire higher part of the spectrum ^{is fed to the exposed * 1} loudspeaker (so that a stereophonic effect is achieved ^. The removable loudspeaker can be housed in its own housing, which is designed, for example, as a spray housing · In line with the idea of control, the removable loudspeaker should be designed in such a way that it can emit not only the high but also the middle frequency band »
