I had my suspicions, thank you for clarifying, I’ll have to play with it more now that I understand better what I see. I was clearly confused, so thank you all

Just to clarify, the driver is mounted at S3 in an OD1 system.

I thought you were right
TL introduces mass loading to the cone...I don't know where's the transition from TL to ML-TL, but surely any acoustic load reflects what happens behind the cone.

:-).

Traditionally the cross-sectional area at the throat end of a multiple-segment horn is designated as S1.

I know. It's the rest of the math and programming worlds that are different... Including Europe for numbering floors

If the frequency response is correct, that’s what matters, the thing that makes no sense is that sound is only emitted from one source when there should be two in the wavefront sim. If you draw a Tm using your mouse, in the wavefront sim, everything looks correct, but now you can’t sim freq response. So within the loudspeaker wizard the driver is facing directly at the screen...in the wavefront editor the driver can only face up down left or right. That’s what’s being suggested.

I ran the sims for bass reflex on horn resp and got different results, wonder which one to trust. With horn resp, the displacement increases drastically above about 40hz, where as with winisd displacement decreases above 40hz ion the same manner.....I'm thinking winisd is right.

I am pretty sure that you can trust Hornresp... :-).

So if I set pmax to 0, the curve looks right, then as soon as I add more power to the signal, 1 in this instance, the response changes to what you see in pink....make that make sense. The blue is reflective what I see in WinISD.
