PP Slot Loaded Sub with Alpine SWR 12D2

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.

For anyone having trouble using the old version of Akabak (version 2.1) on 64 bit Windows, it runs just flawlessly under Wine on Linux. I just tried with Ubuntu 22.10 and Wine 8.0. Wine automatically downloaded the MONO libraries for the Akabak installer to run.View attachment 1139841

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.
 
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?
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.
 
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?
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.
 
This is what I came up with.

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.
