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

    Watts is watts when measured the same way. 25watts RMS in 1970 is 25 watts RMS in 2023.

    There were highly sensitive/efficient speakers in 1970 but also many that were not. Watts became cheaper when solid state happened, so speaker efficiency is less of concern for solid state equipment users (majority out there).
