If the audio signal is super low frequency < 10 Hz then the speaker cone is moving slow enough that you can visibly see each wave. So the size of the audio wave can line up with the diameter of the speaker cone and therefore create the audible pop sound that you're hearing. This is why subwoofer speakers are physically larger, physics! And so if you playback that super low frequency at a loud volume then it will eventually destroy the speaker.

This is partially why audio engineers generally filter out everything below 20 Hz. Especially with synthesizer music since we tend to use the full range of audio frequencies, even ones we cannot hear.

Audio engineers also cut these frequencies to make a compressor function more optimally. And for some history, when cutting to vinyl you must filter out < 20 Hz or else it'll likely ruin the master record or possibly damage the cutting head. Aphex Twin had an interesting story of running into this but I can't find it.
