They're not great speakers, there's only so much EQ can compensate for.
However, given the physical size.. Push the lows, drop the highs and try and sit the mid in between the two extremes (in a slope). Perhaps a twinge more mid so it curves a little more. Honestly though, just toggle the sliders until you find a good response, i tend to auto-eq everything but i don't listen to music on the go, via my MBP's on-board speakers.
Also, theashlands gave you a recommendation that he thought might help. I agree, dropping the bass is not the way but there's no need to be rude.
Just a thought.
