Here is my take on the EQ.
Please report your findings, positive or negative!
For the score rational your journey starts here
Explanation for the sub score
The following EQs are “anechoic” EQs to get the speaker right before room integration.
If you able to implement these EQs you must add EQ at LF for room integration, that is usually not optional… see hints there.
The raw data with corrected ER and PIR:
Score no EQ: 3.9
With Sub: 6.0
Spinorama with no EQ:
Directivity:
Better stay at tweeter height
Horizontally, better toe-in the speakers by 10/15deg and have the axis crossing in front of the listening location, might help dosing the upper range. Explanation here.
EQ design:
I have generated two EQs. The APO config files are attached.
Score no EQ: 3.9
With Sub: 6.0
Score EQ LW: 5.8
with sub: 7.7
Score EQ Score: 6.4
with sub: 8.3

Spinorama with no EQ:
- Not flat at all
- Significant directivity issue (no waveguide)
- HF ragged
- Nice LF extension
- Generally lacking in the engineering department at the price, old school acoustic design
Directivity:

Horizontally, better toe-in the speakers by 10/15deg and have the axis crossing in front of the listening location, might help dosing the upper range. Explanation here.
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
- The second, labelled Score, starts with the first one and adds the score as an optimization variable (here).
- The EQs are designed in the context of regular stereo use i.e. domestic environment, no warranty is provided for a near field use in a studio environment although the LW might be better suited for this purpose.
- One can model the EQ with Vituixcad by using the DSP "Generic" setting with 96000Hz sampling rate.
