Maybe we should study/investigate this ? A stub at the end of the upstream ‘TL’ that’s as long as it’s second resonace? I dunno if it works as well as the offset driver position at 60 cm that would prevent it from even existing?

the drivers offset is about 5''/12.7cm in the red section and nearly twice that in the blue section (?)
I don’t know what that would do in such a complicated box but that measured resonace with the red arrow on it is the same 1/4wave length as 1/3 of the blue resonator?

Driver offset ?
25cm is 345.6 hz
15cm is 576 hz…

Your 2nd red arrow (L23) should end at the speaker mounting board.
All the other red, blue, and green arrows are correct.
If L12 = 15cm, then L34 = 15cm + thickness of wood + the height of the 90cm2 CSA.
DMB is the man!
I saw that video yesterday or Sunday night. $80 is ALOT for a 2" sub. I wonder how they would perform in an existing sound bar.
Might fit as a suppository to resolve @maxolini constipation issues? We need a volunteer(for science).
