It is because the speaker power consumption depends on the music (or audio) which is variating according to the audio signal, the average power consumption will match below the full power 12W.
On the other hands, the router consumes constant power at 12V 1A = 12W, means full power. Therefore the 5V-->12V convertor for the router gets much heat than the speaker one. |
