From my test there are a changing, I have realized a folded version by respecting the length and the cross-section and results in a peak around 100 hz, instead with a straight pipe doesn't happens.
I have both versions and do not have the problem.
Could it be the location of the folded version?

No peaks for me, actually some dips in the lower region, but they are room modes.
Bjorn..
I'd like to thanks for such an incredible design and willing to share it with us.
the speaker sounds so good and Precise, the bass is fantastic....
made it based on Tabaq 2020, with speaker Peerless 830987 with BSC 1mh + 5ohm.

Mas Penk you did a really great job there, I love how you been able to manage the corners
beautiful, congrats and enjoy the music !!!!

2 Drivers in a box means double Vas, so the design would have to be changed. In other words: This is not a good idea.
I tested the walls in our apartment and they are relatively straight. Therefore, I have been thinking a while about “bolting” the front baffle of a speaker in the corner formed by two walls.
I read this thread and internet and have not found any actual implementation, still the comments that corner loading increases bass, so maybe I will need to tweak, or just omit, the bsc circuit.
I do have some 10F 8414 from Scan Speak. These are 4”, have an Fs of 100Hz and Qts of 0.51.
I looked at the attached pdf and the dimensions could work well. I can manage the 128cm2 with an internal width of 16cm (16x16/2 = 128cm2).
Is it better to have the opening pointing to the front, or can it point to the floor (or maybe ceiling)?
Many thanks!

If you place the vent to the floor, because you have the enclosures mounted on a corner, it will look like a flared up vent, and dimensions will need to be simulated and changed accordingly.
If aimed at the ceiling, then no problem. Unless you put them on the ceiling instead of on the floor. Remember to flip the design upside down, so the driver will be much lower, but you could hang them higher and have the driver fire up at ear level.

You could make the port "external" or make a foot with a similar geoemtry. Please take a look at the image enclosed.
By making corner speaker, you will probably have to add some more stuffing, you can test to see what works. The problem might be a dominated bass, which can be controlled by suffimg. By adding more stuffing you will also have an even better conrol of the displacement (cone movement) resuling in a clean bass and sound in general.
Have fun!

Shouldn't it be possible to double the enclosure and the port area, and then have the two drivers meeting where the center of the one driver was?
On the right is one of my first pair of TABAQ from 2018. I didn't have a car back then, so I couldn't buy sheet material locally & instead paid an online wood shop to cut the MDF & deliver it to me. The quality of the cuts was awful, but they sounded fine.
Now that I have my driving license & my first car, I can buy sheet material from my local DIY superstore & they just happen to sell 0.81m long sheets which will fit in my (small) car & are just long enough to make TABAQ with! So to continue practicing my very beginner woodwork skills I've made one replacement TABAQ & will perhaps start on the second one next week.
I have some black bolts on order to replace the silver ones with, so they blend in with the black of the driver's basket better.

hi Guys again,
i know it might be silly question for most of You but could you explain in the simplest way wires connections from terminal -> notch filter -> speakers?
all the notch filter wires are connected parallely -its easy.
notch to speakers in series, so + speaker to - filter and -speaker to + filter.
What about terminals? + Filter to - terminal?
regards
