Hard to say what's going on with the speakers without a rather comprehensive set of measurements. What you are hearing might be something that can be addressed in the crossover, but some things simply cannot be. Sorry I know that doesn't help much.
You mentioned other people getting good results using a slightly different crossover. In my experience the difference between a good crossover and a lousy one can come down to one dB difference here and there. In my opinion, crossover design (which includes passive equalization of course) is the heart and soul of loudspeaker design. It might well be worthwhile trying that crossover mod that others say sounds better in the midrange.
