“Watt” is a measure of electrical power. The “watts” of speakers means how much electrical power the speaker can handle. For example, a speaker of 100 watts can handle electrical energy input of 100 watts.

It is interesting to know that a speaker of a higher power does not necessarily give a louder sound. But it is important to note that, your amplifier or player should have a similar power output as your speaker power if you want optimal performance from the speaker.
