If your room acoustics cannot be improved, you need to use room correction.
Either use a preamp with this built in like Antimode or Anthem, or insert it between your pre and amp. I use miniDSP myself, but on the subwoofer, and because I already have all the room measurement gear I would need.
Looking at measurements, this is a low volume listening speaker, with a built in U/V shaped curve. It accentuates the treble and bass. A room correction program may try to change both, so you'll want to get something you can control so you keep the original character of the speaker.
