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

In real life you hear sounds from individual things as vibrations of the air. There are many different vibrations coming from different directions, and when they hit your ear they are combined into what your nerves identify as sounds. For a speaker, all those different sounds are combined by microphones into electrical signals, that are shaped just like like air vibrations your ear recognizes. When the electrical vibrations hits the speakers, the speaker vibrates the air making the combined noise.
