Passive electronics, like cross-over components, can't boost dips. They can only cut signal levels. Your use of the EQ is the most appropriate way to fill in the hole. A parametric EQ with fine grained controls for center, width, and slope would be idea. But if what you've done improves the sound, then it may be enough.
