How do speakers create so many layers of sound, from one or two cones vibrating. Pt 2, how do the cables carry soooo much information to a passive speaker from the amp.

Question

Title explains it? Passive speakers blow me away – that they are getting all of that info from two small cables from the amp. It seems incredible.

And how is there such separation and depth in the layers of music when it’s coming from more or less the same cones.

Answer 1

It’s part of the fundamental nature of wave math. You can add in as many layers at different frequencies as you want and they’ll super-impose and phase through each other without ever losing information. It works for light, water, sound, whatever.
