Thank you for your answer
I wasn't sure about how far up to measure, I suspected I was taking it too high
I added the smoothing because the higher frequencies was very jumpy, but here is a 'fresh' measurement with the scales as you said. I'm a little bit in doubt about the target curve (blue), since I was a bit in doubt wether to use "subwoofer check levels" or "main speakers check levels" in REW settings, but the results are only differing by 1 dB or so.
But here is the graph. The sub is by the way equalized with a BFD.
