Default Do tapped horn designs scale?

I was looking at Volvotreter's 38Hz Tangband Tapped Horn using a 6" driver. Tangband also makes a 8" driver. Given I have no design software and I know the dimensions of the 6" horn cabinet, can I just scale the dimension up to fit the 8" driver? Correct me if I'm totally off here, but I was thinking the 8" would go lower and still not be a huge cabinet like a 12" or 15" would be. I could even fit two in my system if needed.

On this sort of design, you don't want to guess and you don't want to assume.

No need to guess since HORNRESP is available, free and easy to use.
Don't assume drivers from the same manufacturer are going to have "similar" T/S parameters. You need to look them up and feed them into HORNRESP. There are plenty of HORNRESP examples to get you started

This bears repeating.

The short answer is no.

I did download the software but on initial glance it might as well be in braille. I looked through the help but it doesn't make sense to me. The speaker specs don't seem to plug in. It looks more like you tell it what horn you want and it tells you something else. Sorry for the total confusion but this thing just makes me feel stupid.

I built this from scratch:

But this seems to be beyond me:

You can go to the tapped horn section on William Cowan`s site. William Cowan's Homepage
Scroll all the way down and you find a TH script for AKABAK to copy.

Hope this helps.

Thanks I'll take a look and do some reading. Looks like its time for some "schooling" to get up on the learning curve.

If he is having problems understanding HORNRESP, then recommending using AKABAK does not make much sense. Perhaps I am missing your logic.

There are already HORNRESP setup ups for VOLVOTRETER's TH sub. Modifying one of these would seem to be easier. However, at some point he is going need to roll up his sleeves and get some degree of understanding about HORNRESP. I think it is worth the effort.
