Do speaker watts add up?

Question

Audio

I don't understand the sound device from a physical point of view well..
Do the watts of the speakers add up? (or rather their volume).
For example, a 300 watt speaker will sound at the same volume as 6 small 50 watt speakers at the same time? Or I'm wrong ?

Answer 1

Here, it’s not watts that add up, but decibels, and they add up logarithmically, if you add two columns of 100 dB each, it will be 103 dB, and the decibels that the speakers give out already depend on their sensitivity, and a few more moments pop up.
1) decibels fall with distance from the speaker (and even depending on the speaker pattern), that is, taking 100500 speakers does not get 100500 decibels, but you can get a volume more or less evenly distributed over the area.
2) interference, echo and other delights - the sound quality does not increase from an increase in the number of speakers.

Answer 2

In a simplified form, the power of the speakers is calculated by the most powerful speaker.
