You most likely have boost in the treble region. My suggestion is to disable any EQ that is applied above 300 Hz. It's always advisable to check what your AVR is doing when it comes to calibration. In many cases it's a good idea to insert a MiniDSP 2x4 unit inline with the LFE output.
Understanding and interpreting the results is the real challenge. You have two choices. One is to spend many years learning, studying, experimenting. Part of the challenge is also sifting through the myths and misinformation, of which there is a great deal. The other is to engage someone who has done that and more.
