I have no idea how many ohms to eat to understand this lol im just joking with ya but this is way over my head
Where does the golden ratio pull from? I do understand this but I guess I’m missing about half of it, do ur folds have to be at 3,6,&9? What happens if they weren’t or is that just a standard I guess for the given types? I’m also really I guess missing the most important part which I guess is how this is relating to what frequency response I’m going to get or how to connect the 2 together? Is there a formula for this or?
The key to everything is in the offset driver TL to start.
300x .349206349 is 104.72857142…
104.72857142 x3 is ‘pi’
but, this is more important
Pythagorareum theorem:
1728 (C)
864 (B)
solve for A in A^2 plus B^2 is C^2.
A is the exact location of earth right this very moment. or even more accurately twice a year precisely like a stopped clock is correct twice a day.
But Saturn is exactly 9.55 to earth and its location.

. The square root of the speed of light is 1731.45158107005
the square root of 1/4 SOL is 0.865725790535.

Now look up the size of the moon and the sun in radius and diameter of miles and kilometers precisely.

pretty darn close if you ask me.
Same as 250/254

conversion of an inch to a meter, 100 cm is 39.37”.
Put byput 1÷2.54 in a calculator and realize how many decimal points are not being shownAnd dig those Up and write them down all of them.Because they are saying something that nobody looks at

Long story short.. 11264/7 and 2.75/7 are Equivalent in radians of the conversion of inch to centimeters and the mile to meter
0.125 and 512 pi
4096x
between them
you recognize somethings going on with numbers that you didn’t ever before because you never receive or used all those decimal points in order to see beyond what you were missing.
so this whole story goes much further and into different varieties of quarter wave layout but the premise is already set in place at the simple driver entry location into any TL whatsoever that has been known for about 100 years or so ? As 0.349206349(22/7)/9) or 0.3490658503988(pi/9)
Or 0.34995625546806649)(80/2.54/7)
All are very very important because the speed of light the second and the meter are all in the same definition. But that has been flipped around and screwed (as recently as 2019) as has the centimeter (in 1954) Enough to confuse anyone who’s actually working with acoustics or astrophysics or any of these things that use the volume of a sphere or spherical surface area and expanding inverse square law, etc
Assume: a lie or awkwardness in the education system we are all brought up in and how it leaves out details that more and more matter and you scratch your head later on in life wondering WTF???’ That’s because you didn’t know, you didn’t look(hopefully until now)…
349….. is the speed of light (c) ^4 in miles per sec. But there is no speed of light because there is no such thing as a perfect vacuum.

Look. The golden ratio is hiding in everything. you just gotta find it. you’re not gonna see anything unless you actually look? it goes much deeperThen a simple 0.618 sitting out in the middle of nowhere and is much more complicated than somebody could type without you actually participate in what they’re speaking about. This means looking at 1÷2.54 in your own calculator…And then moving forward from that point, Step by step
Speed of light is based on a meter, and the second and just less than the number three.
The golden ratio is just shy of 1.618 In the kilometer /mile conversion already. There’s a reason for that

I used your input values for the box dimensions and I got this:
Basically identical at lower frequencies. Note that the version of the workbook I used is 0.8 though. I suggest trying again with the latest version of the workbook from the website, to see if you run into the same issue again.

I got the same exact results as before, I even went and deleted all my saved files and the original para download, I deleted all my files form hornresp import folder just to make sure something wasn’t getting crossed. I’m so confused lol how did u get different results than what I did? …..I just need to learn the hornresp program better where I don’t need a boxplan, I just need to be able to wrap my mind around what I can manually input in hornresp, and honestly I’m almost there it’s just hard because I don’t fully understand what is considered s5,s6 etc. if I just knew what measurements went where I could do it on my own but I don’t and there’s no where to learn it. I just keep hitting these dead ends and it’s frustrating but I guess that’s why it’s diy lol I appreciate ur help I’m just at a stand still I need to be able to pay someone for a class! Lol
I think the issue that you ran into is fixed in the latest version of the BOXPLAN-PARAA workbook, version 0.8
Here's what that part of the spreadsheet looks like in the new version
Check the difference in predicted volumes for the horn. The version of the workbook that you used shows the horn volume for the TH model as over 300 L, and significantly higher than the horn volume predicted by the PH1 model. With the newer version, the Horn Volumes of both models differs only by 3.1 liters.
from this picture if i did the arrangement how i wanted with the vent coming out of the side of the box, (how do i explain this? basically what you have labeled as s8 and s9) if i used the side on the enclosure directly across from them, how would i label the box at that point?

would this be correct? and also what is the difference between s2 and s2s or s4 and s4s? what is the s meaning?
just to avoid confusion i am comparing to your layout David on comment #819.

Another question and this is just me trying to figure things out, not saying this would work just another day of many hours banging my head on the wall lol jp not really just doing what i love but anyway
using these numbers
i tried to draw out in a very rough form lol what i could make this look like
ignore the s labeling that was from something different. However, in theory would this layout be correct with using the given number from the hr pic? the parts filled completely in with blue are just nothing they would be just unused space inside the enclosure.

David introduced the ability to define the path along along a horn in a series of abrupt steps rather than an expansion from step to step. "S2" and "S2S" is how the abrupt increase in CSA is defined in the Hornresp model. For example, consider one section with a CSA of 100cm^2 (S1-S2) and another that's 200 cm^2 that are joined together at S2. In that example, S2 would be 100 cm^2 and S2S would be 200 cm^2.
So s2s is basically telling me how large it needs to be after the joining of s1and s2, before you would move on to where s2 and s3 would meet?
This diagram shows how S2 and S2S are used in the model (if you've going to define an abrupt change in CSA at that point
awesome the diagram makes it so much more understandable lol because i was defiantly lost for a minute lol
i tried to relabel this one using what I took from what you said Brian. Would this be labeled correctly then?
S2 is at the driver's axis. S2S works out to be the same as S2. It's only from S3 onwards would you see sudden changes defined by S3-S3S etc, depending on which configuration you select for the mouth. The challenge with this particular workbook was to come up with one "model" that could be used to describe all three mouth options.
Ya I got that s2s was the same given the specific numbers That I was working with, i just labeled it like that trying to show that would be were s2s would have been found if I didn’t have the same numbers for both. Well if that picture is labeled correctly then I am stoked! I feel like that was a huge step foward in understanding taking numbers from HR and turning it into an enclosure design. I appreciate all your help, and I’m sure I’ll have more questions soon enough.
Actually it isn't labeled correctly, LOL. S4 and S5 in all versions of this particular design always describe the last section at the mouth. There is an option in the spreadsheet to show the sample points, but unfortunately it does not label them (I could not find a clean way for the spreadsheet to do so).
