My reply is just a guess. A poorly-quantized saw wave will have “bit-crushing” artifacts at higher frequencies, which can imply the existence of a frequency that’s too low for the speaker to handle. The video link is to a video showing bit-crushing effects applied to saw waves (and others), along with the audio. Headphone warning: it sounds pretty gnarly. https://youtu.be/Tv5c8gPYwFs https://youtu.be/Tv5c8gPYwFs See also https://en.m.wikipedia.org/wiki/Psychoacoustics#Missing_fundamental https://en.m.wikipedia.org/wiki/Psychoacoustics#Missing_fund...
