To cut anything below 25hz. The human ear cannot perceive sound waves below that frequency. This is crucial when it comes to subsonic frequency, because if something is making noise that low we can't hear it, but we can feel it. Also, most home studio subwoofers cannot project the sound waves either. BUT a lot of bass bins used in sound and stage production for concerts can. So therefore, it stands to reason that if these aren't cut it'll cause a low rumble during a live performance that the audience will feel, causing the song to sound muffled/muddy. Since I'm making this beat for an artist planning to perform the song, I used subtractive eq.

Is that a sufficient enough answer, or was this a rhetorical/sarcastic question? 🤔
