Path-length, throat area, room modes will set the amount/amplitude of ripple, ultimate usable low corner F.
200cm2, 400cm2, 800cm2, 1600cm2, at 120 cm increments? And split at 360cm by a tapped driver entry? Substitute 120cm for 80 cm if needed at two points? And put the driver at 200cm/0cm start middle whatever you wanna call it...tapped ...split. Now shrink the CSA used in each to a-lesser and lesser area, and i start to see a happy median? Yet i get confused because theres a fold in those all thats not represented and if its a 180 turn each time its a 50/50 LP filter for each as upstream frequncues? Am i to guess? or can i guess? i can see offset driver works in the same way... but im
Not offsetting a driver im dividing its entry. Something seems to work here and if i cant sim the folds i cant see the idea i can barely create experimenting with lots of pvc pipe parts over and over

In the next sentence in post #7, I wrote "the ported cabinet...", just forgot to write that in the sentence you quoted.
That said, a “V” (slot) loaded driver in a ported cabinet could be thought of as including some degree of "horn loading".

4)One is harmonic intervals inside the folded lengths?
1) The photos of the actual construction template drawings in the "Lab 12 Domino DFLH" thread are the only ones made.

I don't understand your questions 2, 3 and 4.
