LORDSANSUI's smallhorn3 has a "J" bend geometry so should be closer to a good straight than other folds.
Below is one of RCA-Fan's horns with a J path

Sorry late to this -- which one is the smallhorn 3 geometry in the list? Thanks.
The Smallhorn #3 was not published in the website but post in the thread below:

There are also the 122L sealed 122L vented models, but the 3D isn't complete as the 94L sealed one, but they are fully operational for simulation.
Here's the input Z for CUBO12 loaded with a Pyle PYM1298 12" speaker. PYM1298
was built by Eminence and quite close to Kappa 12A. (a fave of mine)
Cubo 12 is nicely tuned and makes a nice fat "horn-like" 60Hz sine wave in my listening space.
I guess it makes me a "junior CUBOTEER" ;^)

Is there such a thing as a "baby Splanar" - say for a single PA310 to get a taste of the concept? (A paraflex could be fun also)
IF I copied your input screen correctly:

15PZB40 lossy Le

Is that model for a PA310 or a 15PZB40?
Gee- - that's very impressive - I've got one for you to spin from Youtube for PA310-8 to see if it oes what's claimed an worth building.
Its' aspect in this picture looks a bit off as is supposed to be 550mm x 550mm x 420mm external with a 384mm internal width.

Here's what I get eyeballing the little PA310-8 Youtube plan. I did not know what to do to model the offset.
- it looks good to 20V input at 41Hz - -ok for indoors support of smallhorn3 in a small house trailer
15TBX40 ought to sub fine for 15PZB40

@BP1Fanatic - Extreme thanks for the extreme effort and plan - that looks like a winner and may well get a build. I'l put 15TBX40 spec in your hornresp input.
Mouth/vent exit size is so small ? I had to cut mine open here in a paraflex version that ‘chuffed’. I dunno drawings are deceiving
That's why I provided the Particle Velocity screen in my post. 412.9cm2 is almost half of the 855cm2 Sd.
412.90cm2 = 16" x 4".
619.35cm2 = 16" x 6".
825.80cm2 = 16" x 8"...855cm2 = B&C 15PZB40 Sd.
1651.61cm2 = 16" x 16".
619.35cm2 = 16" x 6".
825.80cm2 = 16" x 8"...855cm2 = B&C 15PZB40 Sd.
1651.61cm2 = 16" x 16".
