Why do lower frequencies in speakers require more power? Shouldn’t it use less power since the speaker vibrates less?

The Short Answer

Another way to think about this is the question: Why do treble sounds travel farther than bass frequencies? To answer this, take a look at the waveform of the frequency in question. The treble wavelength will be much shorter, meaning that for the same power, an audio source can achieve a higher total sound output due to the shorter wavelength. Let's say the treble frequency is around 13kHz, while the bass frequency is around 40Hz. This would mean that the treble frequency is 325 times shorter than the bass frequency, thus leading to the conclusion of both your question and the question I presented. Since a lower frequency has a longer wavelength, the speaker moves more to achieve the same output. This is why you can see speaker cones moving more during bassy music more than treble-y music. It travels farther because, again, less power is needed since it's a significantly shorter wavelength. Hope this helps!
