Like Kal said, the slope of the crossover is also important. That will take care of the 120 to 200 Hz range.
However. also like Javachip says, if your sub is crossed over that high, you're going to localize it. Even more problematic in my view is the fact that your crossover is is the audible mid-range for human voices, to which the ear is most sensitive.
You may not want to hear this, and you didn't ask in your thread, but I think you should seriously consider new front speakers if they have to be crossed over that high. There are many respectable, inexpensive, smaller speakers that don't have to be crossed over that high. There are too many problems that your settings will cause that will noticeably detract from the enjoyment of your HT.
