Ok, thank you so far. So to confirm this; double the coils (woofer), half the capacitors (woofer, but not C4), double the R3 to 16ohm, compensate -3db with the resistors in HF schematics. Can you confirm my math in the earlier post? Does it show?
My intention is to take measurements when the speakers are ready to confirm that is working as designed. But I understand that it should be build with the right parts. All the parts that I have are new and I thought that I have the 2226H, but what I received was 2226J. And the private seller didn't have the 2226H left anymore so I will try to make these work.
I will send some pictures when the building starts.
Br,
