I have a small SBC (Khadas VIM3) running Chrome OS. I wonder if I can install Wine and use that for my Akabak computer? Fun stuff but I don’t have time to mess around with computer OS’es. I am using Oracle’s VM right now and that works on a Win 10 PC but having hard time installing Win XP into VM on my new Win 11 pro machine. The install of XP sort of hangs and goes nowhere.

You probably can. I just am much better at Akabak than HR. The investments I have made in blocks of scripts which I can draw upon for me makes sense.
Can you do a dual driver push pull slot loading reflex box in HR? Please share if you can do it. We would all benefit.
Sure you can. Offset driver with two segments (closed end to driver, driver to open end), ported rear chamber. If you were to get clever about it, you could include the effect of having the driver's magnet in the slot.

Assuming you are using 0.75" thick wood, is the enclosure 16.5" deep external and 15" deep internal or 15.5" deep external and 14" deep internal?
The script is not accurate unless you can explain an external depth of 16.5" with an internal depth of 14".
16.5" ED - (0.75" wood x 2) = 15" ID.
15.5" ED - (0.75" wood x 2) = 14" ID.
Does the statement above equal three 40 liter chambers?
Regarding 15.125in D x 13.5in H x 12in deep per chamber, which number is the width and which number is the depth?
That depth might be off and should be 15.6in but not a big deal as it is used more for calculating the baffle step losses in 4pi space depending on where vent is located. In this case, on the front so depth has no effect. It’s been a long time since I worked on this script.
Sorry one of these is Width. You will have to compare to sketch and see what makes sense. I generally describe dimensions as width then height then depth in that order, if that helps.
Nice work but that’s not the same as having the vents come out of the slot - which provides acoustic feedback and a bandpass 6th order alignment. What you have is slot loaded bass reflex.
BOTH styles are similar to BP6 alignments. What I did was a BP6P style. You want a BP6S style. The model would not change. The build would be different.
D@/\/\N it, I corrected the speaker mounting boards in the front view.
Previous post, I had 13" x 13".
13" x 14" are the correct dimensions.

I think if the model does not change with the vent blowing by the driver face, something is wrong with the model? That’s why tapped horns are different than a plain back loaded horn. There is acoustical feedback between the front and the back via the vent. This will change the response drastically - reduce the upper bandwidth and improve cone movement control for higher SPL.
Look at how HR is used to model tapped horns - the same driver front and back is exposed to two different paths of the speaker.

In the BP6S style PPSL, I can see using the TH function to model the enclosure. However, I thought PPSL's should not function like a BP enclosure?
