Electrically overpowering a speaker is caused by
continually playing the audio system loud
, resulting in applying more power to the speaker than it's “rated” specifications. This is what causes speaker voice coils to “burn”.
Is a bigger voice coil better?

larger coils tend to have better control
.

What is the dust cap on a speaker?
The dust cap (also known as dust dome, or dome) is
a gently curved dome mounted either in concave or convex orientation over the central hole of most loudspeaker diaphragms

Larger magnets (and stronger audio signals/voltages) are necessary to move large speaker cones and subwoofers
. However, the overall quality of a loudspeaker depends on more than the size of its magnets.
