Hi - I think its more a matter of wanting more control over the EQ. For those that are not familiar with the Bose S1, it has a built-in "positional EQ" where it detects whether it is on flat (such as on a table), on it side ("monitor" position), tilted back, or on a speaker stand. It has 4 different EQs for each of these positions.

On the "monitor" mode (like a stage wedge position), the EQ automatically reduces the amount of bass. My note was about if you want that bass, you can bypass the positional EQ by doing something that presses the sensor switch inside the speaker-pole hole in the S1.
