Thanks again man for posting those.
I don't mean to sound ungrateful though, but I'm still unsure which one is the most up to date plan. Also a plan with brace sizes and hornresp info too.
There are multiple hornresp data floating about but no idea which plan they are for, with varying results, And brace images with no sizes.
Surely there is one 'main' plan that had the best overall outcome, with all that info in one place like most other plans I have seen?
Id just like to have everything 100% before I begin building anything.

Because for example: here are 2 different hornresp info for the SS15 I have found through here. I have used the same driver for both. No idea which ss15 plan they are for though but quite big different outcomes.
The one in bold I'd be happy to build, but the other one not so much. (not knocking it at all, just for what I want I'd prefer that certain one)

I can tell for sure that the black graph is not the original SS15, the original design made with one sheet of ply Did not hit that low cause the horn length.
There was some mods in the thread to make the SS15 hit lower , it was bigger and thus need more wood, now if you want to hit 40hz flat or lower, the SS15 is not your cab.
Remember the iron law? Low,small,loud....pick 2
Take a look at Art's Keystone
XOC1 TH18
Ricci Skram
Those hit lower but are bigger and you need 2 or 3 sheets of 3/4" ply ...(18mm)
Define your target freq and SPL then
Look for a cab that fits
Also you can use Brian's spreadsheets to tweak
Known TH fold types like MTH30, SS15...Othorn...etc.
Hope this helps

The black graph is the hornresp info from page 2 of this thread posted by jbell himself.
Cool cheers I'll have a look at the spreadsheet.
I don't necessarily need to hit 40hz flat. That black graph basically would be perfect for what I'm after, considering the size, amount of wood needed, my estimated overall weight and for what I have planned would be near enough perfect I think. Perhaps slightly too physically big would be the only downfall maybe.
If the Tham15 could be made using 12mm ply or maybe 15mm ply then that could also be a contender as it's physically smaller.

If you refer to post #38
That's the 1st approximation jbell made
And if you look closely
It's not a 40hz flat ... It's along the 48.5 hz area
As you see the 40hz area have a down slope ...
That's why some people considered the SS15 as a 50hz cabinet
It's flat to 50 certainly
If you happy with that go ahead
The tham 15 don't go lower than the SS15

"The 'iron law' still applies to a TH enclosure.
I don't think 40hz and 100dB are possible from a 2' cube.
50hz, yes, 40hz, no.
#9 is a good example of that at 90dB at 40hz.
"in reality it goes lower"
With room gain, I might buy that. In 2Pi or 4Pi, no way."

Ah ok I see yes you're correct. Is there a final approximation then, that is what I am looking for?
50hz flat at that spl would be perfect.
I like the iron law quotes too they explain it well.

Ok, so if you are cool with 50 hz
SS15 is excellent.
Now...if you want more SPL you need a higher Xmax capable driver and do more bracing.
Or more cabinets ,
Remember each doubling of cabinets will give you 3db more and if you double power it's another 3db more.

Cool, 1 cab would be all I need.
So I can see from those pictures you posted previously on the .step file the position of the braces. But there are no sizes for the braces. I'd assume they need to be exact?
I haven't seen any braces on any of the plans I have seen for it. But I'd imagine they're needed as it's only 12mm ply.
Also any idea if there is a final approximation of the plan please?

the original plans do not include bracing , that is up to the cabinet builder.
There are many examples of bracing trough the forum for different designs.
You can get ideas and apply them as you see fit.
For the plan let me look if I have the one marked as the standard , cause there was some variations along the thread.

Cool thanks again man. Im going to have a proper look again later at it all.
While on my lunch now I've been having a look at the Tham12 and the TH-Mini Clone.
Cant find any plans or hornresp info for the TH-Mini Clone. Do you happen to have that at all?
All the info is available perfectly for the Tham12. But id like to compare the two properly.

The thmini is a danley cabinet , clone I have not heard of it
The tham 12 is on the martinson blog webpage
https://www.martinsson.cc/blog/index.php?m=03&y=12&entry=entry120315-210219
Where you will use this sub project ?
What is your choice of driver?

Is that a guess of the internals ? Or it is declassified ? I mean the patent expired ? I know it is not permitted to post the internals of copyrighted commercial designs, so somebody chopped one up and get the dimensions of the internals ? 😵💫
I know that is happening since a long time but people who get an original to be opened up is cause they will clone at least 8 of those or more. But they don't post away.
They just use for their rigs and don't say anything.

Could be fairly close to the TH Mini, but the recess on the upper (or lower) front panel is obviously different.
I'd doubt that DSL uses the corner angles depicted.
