If your intention is to help people it would be beneficial to clearly state what acoustic issues you forsee.
For myself, looking at the LF system alignment, I'd suggest there may in practice end up being a lack of gain in the mid - upper bass region, especially around 100Hz, and particularly when floor-bounce is factored in. The minor gain-peaking at Fb could also be an issue, but since it isn't tuned especially low, I suspect it may get swamped by room effects so it may not be too significant. Depending on how tightly (narrowly) tuned the box is, there may be some issues on that front, although this being a QW variation, it's likely this could be adjusted without too much work. I have to take the greyhound out for her morning walk shortly & finish writing a lecture, but if I get a few moments I'll have a more detailed look at the alignment & what else can be done.

Please, let’s keep it direct or we will get the sam eprice increases seen with Cube.

In my small experience,I can imagine simulation and measurements ain't show how it sounds all.
I will make basic vented box you suggested because it was designed for. Also I want to dIY and I can compare.
Luck around 100Hz,I concentrated on port output gain,I made another design. I have no idea how about floor-bounce effect and what I can do for it.
I noticed there are a lot of things to take care for design, I am trying to balance in simulation.
Before I built Tabaq,I liked how the bass sounds but I didn't want to add baffle step circuit.
So this time I want to build which doesn't need one.
but If I designe bigger and wider baffle,low-end bump apper,smallish box make it smoother but it will need BSC because smallish box size.
Now I am losing how I want to design it.I need to look back vented box? Well I like TL bass sound basiclly.

I took these measurements with another program and they are almost the similar with your measurements.View attachment Shinji Tamura.pdf
Thank you for your simulation.
I am still puzzling box volume and port size.
Probably I can listen how sound changes by changing back panel angle
and port length.

If you already have a drawing for these drivers, please send it to me by mail
and I will calkulate this date for you.

I made box detail.
I made bottom 50cm^2 but I will try straight TL to 0cm^2
Bottom TQWT if I don't glue back panel.

Thanks...will do. Do you have any listening impressions with this driver and enclosure combination?
especially, any comparisons with sonido's enclosure design?
Thx

I had no time to make enclosure yet.
Because of Covid-19,I only can stay my flat one day a week.
Istvan gave me TQWT plan for me.
I appreciate very much.I am too ignorance for design
enclosure now.
For my progress,I want to predict using hornresp
this folded TQWT.
I have an question that how can I count length?

I had no time to build box until yesterday.
Finally finished,adjusted filling wool.
Bass sound is tight and enough deep for me.
Nothing screaming at high frequency.
Vocal sounds detailed also emotional.
F6 amp and Sonido is just like magic.
Istvan send me info about field coil with elliptical driver.
I really curious how they sound.

good afternoon, I also build such speakers. I ask you to show how you filled the housings with a damper?
