Post Subject: Analogy for the Function of the PRPosted by Edgar= on: 11/9/2022
Here is some footage I found helpful in visualising what is happening with the PR. It's of a flame in a tube not a loudspeaker but I thought it serves as a good analogy for the phenomena we are discussing.

Skip to 6min if you want to jump straight to the relevant slo/mo footage. It's interesting the dampening as the system approaches resonance. I also find the geometry of the waves intriguing. It happens just as you describe it rowuk, the system is a Helmholz resonator at one single tuned frequency and it's harmonics.
