project altec vot jbl 4560 style under hornresp

Hi everyone
This is my first post on this forum
I have the speakers: beyma sm115/n and jbl 2445.
So i m looking to do something with that.
I will make my self a arai 290.
I choose the sm115/n for his price, go low and high, just need big volume in bass reflex: around 200 liter.

But and this is why i write my first post here, i m look how to simulate something like VOT, and it look good on hornresp.

So in image

Do you see something wrong ?
S1 92 is not to small ? from the simulation no but hornresp doesnt calcul air velocity first from port, second from the throat wich is smaller than the port...

What do you think about ?

The distortion go up under 55 hz that why i m thinking about something like VOT

Greets!

Images don't open.

Which VOT? Altec used/abused this moniker to include everything from a basic reflex to various types of small, large horn loaded systems, though don't recall one that used dissimilar point source drivers in a cab other than some of the Japanese spec VOTs.
 
thx gm !!!
