That lesson you gave me into a friend. I would like to understand the transmission line just like you! Tell me how you have any digital book?
As for the softer you use, would be fully trusted?
That same month I will make this T-suboover TQWT, and when you are ready, post here, with special thanks to you!
Thank you and I apologize for my impatience!
a hug
Thank you nelnar, you wrote kind words..
Here are a few Url's for you to dig into :

I use the softwares that are 'the tools of trade' here at DIYaudio as they give very good results so far as I can see ..

Bjorno which of the two amplifiers you recommend for this subwoofer:
Bash Bash 500w or 300w?
new driver NAR
Bjorno when he finally managed to keep all the cash to make the subwoofer, the speaker makes the NAR, is no longer manufacturing. Moved to this model, as follows:
Not wanting to abuse you, and considering that I broke the head to get the new calculations, I did not get anywhere.
You could calculate for me?
Below the model and specifications:
Subwoofer 1266-SW-3
POTÊNCIA RMS: 300-400watts
IMPÊDANCIA: 6+6ohms
SENSIBILIDADE: 88db
Revc=2.300 Ohm
Levc=889.758u H
Fo=28.582 Hz
Sd=53.093m M²
Md=44.000 g
BL=9.648 T·M
Qms= 6.989
Qes= 0.532
Qts= 0.494
No= 0.440 %
SPLo= 88.5 dB
Vas=103.554 Ltr
Cms=258.705u M/N
Mms=119.852 g
Mmd=105.783m Kg
Xmax= 13mm

Hi nelnar,
Here is an attempt using the new driver:

Thank you my friend.
Now let's see if I've learned!
The following measures of the subwoofer, as I understood your project.
Note: You like to do I suffer! (kkkkkkk, just kidding)
For now thank you very much my friend!
You are a very special person.

Björnö. Please friend. Respond if the design is correct!
And what would be the fill area?
Hi Nelnar,
You have designed a TL using my numbers for a T-TQWT that of-course can be morphed into an OD-TL.
For this case and for your rear terminus TL, I would decrease the line length to 310-320 cm in order to tune just below the Driver fs, that is :
The internal height would be 155-160 cm.. all other dimensions unchanged.
I rec. you to do so too with your TL as the FR will almost be unchanged.

But I wanted the T-TQWT same.
Once the measures are certain to T-TQWT, what is wrong?
is the position of the speaker?
I even design more cameras for this project!
For a TTQWT, the speaker must be inside, on the divider, and not on the outside of the box.

Björnö.
This decrease in line 330 for 310-320 is only for OD-TL, or also T-TQWT?
NOTE: The first image above is wrong. Sorry. (please disregard).
Please make sure it is correct for t-tqwt?
Hi nelnar,
Which HR input screen did you use for the layout.

Ps. I haven't forgot you but I struggle with computer problems so I may be slow on answering..
