Just to add to @Music or sound 's comments. A while ago I did a check with REW. I measured the in room frequency response curve with the Devialet treble set to 0dB, and then set at -3dB. In the graphs you could see the slope start to drop very gradually from the set frequency of 2000Hz, but it does not reach the full -3dB until 20kHz. In fact, as my in room response is reasonably flat from 500Hz, setting the treble down -3dB gives an in room response that looks like a moderate version of the classic "Harmon" curve. OK - That's for treble, so in your case I would expect no change to the bass at the 100Hz set point, then increasing gradually, hitting +6dB at 20Hz.
