Directivity files of a tweeter on a waveguide

[wonderfulaudio]

Hi,

I am looking for directivity files for a 90 degree waveguide to be used in vituixcad. Can anyone point me to any links?

Thanks and Regards,

Too many variables such database to exist

I am sure folks who have taken polar measurements for their waveguide builds have them.

But with different drivers so to just describe the WG is really hard.

More or less all the 90 degrees waveguides have the same directivity. I am not looking at a very specific waveguide/driver combo, just need some polar plots to have a jump start for a waveguide based project.

Here's Augerpro's thread over at TechTalk ( on custom printed waveguides ).

And here's one participants ( named ergo ) and his measured results for the BlieSMa T34B-4 on a custom printed waveguide;

The SPL Trace tool found in Vituix CAD2 is excellent ( meaning you should be able to grab & create your own traces from this pic or any others found within that thread ).

Cool, so I can convert graphs to files, in Vituix. Missed it altogether, thanks for pointing out.

Thanks to kimmosto for the nice tool.
