Speakers copy the source, a flat frequency response in an anechoec chamber (or floating up in the air), when you put that speaker in a room it will create a frequency response which tilts down from bass to treble, as would a source e.g. piano etc.

In a room that downward tilt is actually wavey in the bass region due to room modes. What dirac/room perfect tries to do is straighten out those waves.

I suppose it's strange that a natural phenomenon can be unpleasant (modes)

but it is only unpleasant in bad rooms, with high amplitude modes(hard reflective surfaces) and poor grouping of nodes (small or bad shaped rooms)

If you were to listen to a piano in a concert hall it would sound good but if that same piano were in a bathroom it may not sound as good
