Any room, especially one that small, will benefit tremendously from acoustical room treatment. It is likely that the midrange and treble are being overwhelmed by the mid-bass in your setup. You could build some bass traps for the corners and some acoustical absorption panels for the first refection points that will tame these bass nodes and early relections.
A few months ago, I did just that and it was the best $500 I ever spent on audio, even though my room is much larger. If you are interested in knowing more about how to do this, email me.
Good luck.
