"What's important is tonal neutrality, correct localisation and a correct sense of distance. This is achieved, among other things, by not splitting the radiation of a loudspeaker across drivers that are more or less far apart, as is often the case with multi-way systems [ME Geithain uses coaxial systems that are close to the ideal point source, the author]. In addition, the effect of the directional characteristic of a loudspeaker is often underestimated: Compared to other frequency ranges, the human ear rates direct sound between 2-4kHz about 2.5dB higher than diffuse sound, which must be taken into account when developing loudspeakers. Depending on the loudspeaker model and the associated optimum listening distance, we make sure, for example, that the loudspeaker is less focussed in the range between 2-4kHz. Otherwise, there would be an overemphasis in this range, which would not be conducive to sound colour fidelity or distance detection - the sound image would appear more present and subjectively closer to the listener."
