Investigating port resonance absorbers and port geometries

step can't provide parametric adjustability - which is key to have a useful model that can be adjusted following the excel sheet!

well, yes and no.

On itself no, but there are plenty of programs out there that can convert STEP fine to parametric by adding rules and constraints.

I would suggest to make a new model then, it's very simple, see the sketch in the excel sheet

step can't provide parametric adjustability - which is key to have a useful model that can be adjusted following the excel sheet!

But I could provide a collection of different printable models in stl, 3mf or step format.

I will also try to model a parametric port in freecad.

FreeCAD I have as well as Ondsel

I am still working on whether the strouhal number limit of 1 is really useful for high quality music reproduction or if it should stay even higher.

I will wait until you settle on a figure before implementing anything further in Hornresp. Would 1.5 be a reasonable compromise perhaps?

Possible to have step file for testing?
