Is it taken as gospel that Neuman were oblivious to all other broadcast and recording considerations of that time? or that the backplate design was intentioned thuswise? That is an interesting proposal, considering the cultural situation before and during that regime. Speeches were important, but the propaganda utility of music and film were invoked often too, aside from the normal recording and film considerations. But then I don't actually know what the thought process might have been, considering all that.
