Thank you. Before I saw your reply, I saw this discussion and links on r/acoustics which in retrospect seems to be the best likely answer. It being a cannon (and not a speaker based device) would mean it’s closer to a controlled explosion than a speaker playing (really loud) music.

There’s still the questions of “how is it so small” (apparently) but at least some aspects are answered now.
