I find this thread very inspiring and relieving -
the graphics (great hornresp/windows color scheme, booger weldz, by the way!) and numbers are remind me of ,,,
let’s start over before you lose your marbles or **** yourself for no reason.😂😂
I would suggest, as it was in the very beginning, to open up the horn response file and Take a look so I don’t have to go on all these awkward tangents and listen to a bunch of fools make fun of someone who sounds like a fool and create such a mockery of everything for you all… Take a look so I don’t have to go on all these awkward tangents and listen to a bunch of fools make fun of someone who sounds like a fool and create such a mockery of everything only in an effort to try to convince people to look at something they could have took upon himself long ago already?
I love it when that types it all twice.. I didn’t do that on purpose but I thought I’d leave it because it’s kind of silly too..
I mean how hard is it to share things on the Internet my God? That’s been on page 1 forever….

This guy who is clearly one of einstiens relatives…
when pointing out the obvious but not recognizing the title ofvthe thread and concept Introduced on page one is suggesting that the things are awkward already???? So take it slowly not a big gulps. Might choke on your own ego before realizing you’re missing the point..
FWIW this thread and specially those screen captures and handwritten pages, in language - colour - structure - style - layout - etc. , makes me think of:

I don’t see anything in that though do you?FWIW this thread and specially those screen captures and handwritten pages, in language - colour - structure - style - layout - etc. , makes me think of:

Lot more to the conversion of an inch in centimeters and people ever look at.
if it doesn’t make sense by now playing the education system. Two years since I’ve built my very first transmission line.
just over one year using horn response.

Whatever you don’t understand it deserves your efforts. I wouldn’t waste anyone’s time posting random nonsense. If you look into this it wouldn’t be a waste your time I promise.

Take Martin kings ‘white paper’ for offset driver entry and noticed the .3496 reference as tap entry location for all TLs
2.8125 is 0.98425
5.625 is 1.9685
11.25 is 3.937

15.52 inches
is 1” x 15.52 = 100cm2.
2” x 15.52 = 200cm2
This is a common thing used for 12 inch drivers in subwoofers to simplify the math /conversion between imperial units and centimeters because horn response is metric and many vendors and TS parameters… and many of us in the states use it along with 12 inch drivers in an area of audio that beat the crap out of everything already… car audio junk)
should we move to the centimeter now? Meter conversion to square mile?
it’s gonna get even trickier… I’m still going to use the speed of light and pie in ways that people don’t seem to want to get over to figure anything out in the first place??
I’m beginning to realize why that dude jumped ship here as well. Years ago and he’s kind of a grouchy jerk already?
if somebody would realize anything here… and that this is how you tap into the stock market (A lot like Martha Stewart ) already as well??
It’s not ‘numerology’ when it’s in a functional part of a subwoofer or any full range speaker to be honesIt’s not numerology when it’s in a functional part of a subwoofer or any foreign speaker as a TL?
Does anyone even build 1/4 speakers in this place? Maybe I’m assuming incorrectly on a couple of things and that might be ?

Wait a minute. Slow down! 😀
You state that Golden Ratio Phi ^2 x SQRT 4 is 5.236.
Therefore that Phi ^ 2 x 1 is 2.618.
https://en.wikipedia.org/wiki/Fibonacci_number
Hmmm. Fibonacci Sequence, eh?
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on forever.
The ratio of successive terms converge to Phi. 1.618...
It is well known that Phi ^ 2 = Phi + 1.
Of course, Golden Ratio is popular in Closed Box speakers to control those sorts of bass resonances you are getting in an undamped transmission line.
But surely it is easier to add damping to get more control of the reflection from the port.

sealed box???? I got impedance peaks equaling essentially in eighth order vented enclosure in both measured and simulated as pictured
This (these , others as well) Is a quarter wave layout in parallel as both sides vent together at the Series exit dual quarter wave paths, the layout in parallel, but both sides vent together at The same exit
270 or 240
90 or 80
30 or 20
300 or 280
360 total 320
-Full length of the long side to exit.
-Full Length of the short side to exit.
-Driver entry in both
-Seperation between tap points of the driver entry

My friend, I know all about horns:
I know all about symmetry and resonances:
But the main problem in loudspeakering, at least at the low frequencies is the room:
If we were serious about sound, we would build loudspeakers in to the wall. We would damp the walls. Obviates all the problems except cone breakup and time delay and to some extent, dispersion and power response.
I have heard systems that deal with these issues. It is not cheap and meets with little WAF.
