That is why I created the convolution filter for the OP - to flatten the FR@Matias
This is what your measurements look like when using var smoothing:

No wonder it sounds boomy still, don´t you think? I suggest using var smoothing and higher Q-values for bass EQ and focus on reducing the most offensive peaks. Those are still very high after your current EQ. Also, i think you pushed the upper bass too hard with EQ and i highly recommend trying better positions for your speakers and/or listening position. I would focus on smoothing out the 70-300Hz region first with better positions, as good as it gets. Then cutting the peaks with EQ. At last tuning the treble to taste with low Q filters.
I hope @Matias will give it a try; IMHO it shall help a lot (even if an additional low shelf is applied)
