Hi,
The Score as calculated by Olive may not be valid with a dipole speaker so the scores are really just reference.
Therefore the score optimized EQ might be rubbish...
Here is the processed data:
Score rotated -30deg No EQ: -0.11

Here is the Spinorama of the EQ version from
@BYRTT
Score 3.27

I then designed an EQ for "flat" LW of my own,
Big LF and HF boost required so be very cautious if you try it as it may damage the speaker.
Score rotated -30deg with flat LW EQ: 4.36

Then I used this EQ as the initial seed for the Score optimization:
Optimized score: 5.71
Even more caution should be applied when using this EQ!!!

The corresponding Spinorama
Improving the score in this case is really about adding a slope to the response

EQing to a flat LW does not seem to change the tonal balance

And the zoom for PIR-LW-ON without EQ, with the flat LW EQ and the Score optimized EQ:
Not bad once EQed.
