As dynamiclinearity mentioned, at any given, whatever any driver is doing at any given time is a complex combination of many different frequencies albeit in a more limited way in a classic woofer, midrange or tweeter than a single driver design. It’s always amazing to me that this can occur & sound realistic.
Even more amazing to me is that a single stylus in a phono cartridge can somehow do a similar but inverse thing & react to the full range squiggles in a spinning vinyl disc & do so accurately! Also similarly but not always true, the better cartridges can’t “ play loudly” either & general their outputs are very low & require substantial amplification to be “heard”. Thomas Edison was one smart dude!!
