I’m an audiophile and home theatre enthusiast. I keep hearing the term “passive radiator” and when I google it everything just goes over my head. Can someone explain like I’m 5?

The wiki page has a good diagram [here](https://en.m.wikipedia.org/wiki/File:Passive_radiator_enclosure.svg).
It’s a cone without the coil. It doesn’t produce sound on its own, but sitting in a box with an active speaker, it will resonate alongside the main speaker. It does a similar thing to a port/vent, helps the bass escape.
