How does comprare 100w speaker of 40 years ago versus 100w speaker in 2023?

Does new speaker have higher efficiency, so less power produce the same level of sound?

I know it’s a not-so-well made question, but maybe we can say something.

Thanks

      This is correct. The power rating is just what the speaker can handle while playing music without being damaged. It’s actually a complicated spec that only relates while playing music, not test tones. There’s no relationship between power handling and how loud a speaker plays for a given amount of power. The standard measurement of sensitivity is made with a mic one meter away from the speaker with an input of 2.83 volts. Some speakers will be loud under these conditions and some will not. 90 decibels is a typical measurement for normal speakers, give or take a couple of decibels.
