So can I make a 1x2x4' bass horn? Or not really?

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".

2)I think ive been chasing this idea and by adding the tap at 3/4 down ive confused it into something its not?
3)Is it the sim or is it the segmental distances?
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.

the picowrecker tapped horn is about that size

Im always trying to fold on harmonic intervals and sneak that into pipe segment expansions in the ‘horn response’ sim that doesnt show a fold but hints at a variety of things and one im particular to has always been a sort of keystone layout shape, though its skewed for the 12” driver i typically use because its motorforce is cheap and expendable... it models in ‘pairs’ like a 18ds115 single will, but i shrink the throat area CSA or add damping in anyway/many ways to fill in the slight differences otherwise usually. i wasnt sure if that was part of this design and couldnt see the pics clearly, or tge outlines on the plywood

Folding on "harmonic intervals" in the Keystone TH, the Domino DFLH, or any other horns I have created has not been part of their design process.
