Hi,
Here is my take on the EQ.
The raw data with corrected ER and PIR:
Score no EQ: 5.4
With Sub: 7.7
Spinorama with no EQ:
- Fairly smooth
- Decent directivity, beaming towards HF as opposed to constant directivity
- Horn probably a bit small for a smooth transition
- Port...
- too much HF but you gotta hear these horns ;-)

Directivity:
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, might help dosing the upper range.

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.
- 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.
Score EQ LW: 6.5
with sub: 8.6
Score EQ Score: 6.7
with sub: 8.8
