Probably the reason how absolutely amazed I am at how good some of these
new techology, small, ****ty little speakers sound.

Better magnets is the main reason. Speakers with rare-earth
magnets can move a lot more air for the same amount of input
signal than the speakers we had 20 or more years ago. Which
also means they're a lot better at overcoming their own
inertia to follow the input signal.
