Hi,
Here is my take on the EQ.
The raw data with corrected ER and PIR:
Score no EQ: 5.05
With Sub: 7.41
Spinorama with no EQ:
- Not bad except the resonances
- The HF peak may make the speaker sound "thin"

Directivity:
Horizontal pretty good thanks to the waveguide.
Better stay at tweeter height
Horizontally, better toe-in the speakers by 10/20deg and have the axis crossing in front of the listening location

EQ design:
I have generated two EQs. The
APO config files are attached.
- The first one, labelled, LW is targeted at making the LW flat, pretty good that one maybe better if you listen ON
- The second, labelled Score, starts with the first one and adds the score as an optimization variable, come back closer to the bare speaker, maybe better if you toe-in
Score EQ LW: 5.78
with sub: 8.03
Score EQ Score: 6.29
with sub: 8.54
