I believe this is the end of almost what trying to aim at?
And if i folded that 240 cm at 120cm+120cm i would fill in the response and because it would be the harmonic of 120cm which is 214hz to its own and 107 is the Fb /3. i probably have misspoken and theres a variety of ideas and options here including other intervals of 240 or compounded approaches. Paraflex is a good one, roar is great, ODTL is outstanding!!! And ODOE TL is the cats meeow, but the tip of the iceberg for a taped driver might be placing it in the middle of two qw paths which themselves are split at midpoint? Or a mathematical version of pipe harmonics and open ended pipe harmonics, etc?
B@se wave cannon, etc... lots to read and lots of ideas!! Heres half of nothing but close to a unsimmed(wont fit into the programs assigned fuctions) guess? 240 cm @ 120/120 seals the deal? Or ? Its only 30’degrees closer in a compound? Vs standard Qw pipe at 90. And however method we can use to describe the phase at various layouts ‘offset’?

Hmmmmm... 56hz is the intersection ~54 in the settings i had for temp and sea level(but just a pipe length )

I guess its 240 and 240 with a ‘trick’ of bass reflex instead to solve this puzzle. I had hoped for a little more?
Brian Steele is in the same path. I want to push him
Farther because i learned a lot from paraflex. Greg, you showed me some things i dont think you quite realize yourself even. But these pieces of brilliant thinking and info from so many great people and places alll come together
it is maxed out as tapped entry to harmonics.
1/4 is now 4/4. Tap it at the 2/4. Fold it at 1/4 and 3/4. Exit at 4/4.
80/80/80/80cm is 320cm.
To see part of it, make that 120/120/80 in TH L12-120cm, L23-120cm, L34-80cm...and its easisr to see. Use the TH sim with 0.01cm in the L45.
Csa is the same, See it now?

There is more. But fitting it into an acceptable region of (an octave?) is a hurdle. But using a tapped pipe is mathematically the center point of helping
‘Make it possible(it seems).
The real full wave seems too dangerous as i must reduce power to see it. I dont mess with thst anymore ive destroyed enough to know trying. Its not useful
To share that info, we will just ruin our equipment trying. I dont want to wreck anyones stuff by sugesting an idea thats going to. So i creep
Up On it in sim . im
Not sure what CSAs to use... but its there to find

The black curve is the 120 + 120 + 80 cm tapped pipe version.
The grey curve is used as a reference and is 20 + 278 + 22 cm. Both have a 600 cm2 CSA and both use the same Beyma 15 inch driver.
What am I missing here (or what have I got wrong)???
Exit is not offset. O.1cm at end
Csa for Vas and Qes is going to skew this for fs.
Gotta find the right CSA as well. It us a tight Vas and a great motor.
I use 200 for my driver, 400 as a pair.
But i open up after this(csa) i segments to create MOAR. And thats when i start to see the GENIUS in all Of these ideas on the internet, between sweden and paraflex and so many things. Its amazing, you are ALL amazing
stepped ROAR. Bisected twice, not 1/2. Is represented in folding halves. Not the sim. The sim doesnt show what i cant tell you or explain without a sim.
Fold ROAR in half for the upper path. Then the large area is left over. now split that into two, increase the csa as needed. You will have to look deeper than one sim. But what you have created is the null for each spot on the REAL sine wave of Fb has been addressed as a circles sircumference with driver at the clocking of 180 (6oclock), and a fold at 90(3), and a fold at 270(9) and exit at 360(12).
Now those are going to put the phase at the end beack to zero
The example 120/120/80/0.1 is merely proof of what im trying to explain. its encouragemebt to see

Please realize your not seeing the results in HR that you will in a single fold in each leg of two pipes split by a driver at the closed end of each. (In series that make the start and middle of one pipe folded once in each 1/2.
put the motor at 240
then put 120cm, twice, on each side of it.
All in series. As a folded twice 480cm. or fold at the motor too(?) this matters!
Now tapped, so its propelled at start and middle
Open end is 480cm total from start, 240 from tap 120 from last fold, 360 from first fold....

Check your phase at various positions, look how long it ‘dwell’ s at The 90-0-90 as compared to a qw pipe(4th order) or compounded however you want to sim it. These things are clues and if changing the CSA to help wave propogation and LP filter the ongoing standing or HF is going to help, then in stages is what attracted me to 3/4 of what i see in ROAR. contrary to a helmholtz flip 180 at tuning, we have a sinewave shape that is severely focused on the vertical through 90-0 - -90.

Have yet to spend any time with the paraflex and all its iterations as at the time seemed a whole lot of effort for getting a bit more over a narrower BW up high.
OK, so multi-tapping a BAWC? IIRC B0$3 has a patent for this and/or took over one when its patent ran out.
Regardless, got a lot on my 'plate' these days, so basically just responding by rote when I can, really don't have time/energy for 'brain teasers'.
Anyway, hope you get it all worked out and assume you'll have to use AkAbak to sim it.
