Will a sudden loud sound damage a speaker?
Playing music/audio too loud may cause damage to speakers due to excess heat in the drivers or even mechanical failure of the driver suspension. Speakers have power ratings that, when exceeded (by increasing the amplifier/volume control), will burn/melt the driver coil and damage the speaker.
What happens when a speaker is blown?
Blown speakers can have any of the following symptoms: High levels of audible distortion. Limited frequency response (especially in multi-driver designs). Low levels of sound.
How do you check a speaker to see if it works?

What causes a speaker to sound distorted?

Why did my subwoofer started smoking?
Clipped, unclipped, dirty, clean, it doesn’t really matter how the power goes into the woofer, it is going to cause the voice coil to heat up. Both the smoke and the smell are a result of those resins on the coil returning to liquid and eventually a vapor.
