Those particular numbers are not normalized and have only a relative meaning. For a better normalized electrical error you should use the electrical error at the top of the results, not the lower gray area.

Yes, that is correct. Non-magnetic weights only should be used. We have added some text in the manual to reflect this (see attached photo).

It looks like a port resonance. Can you share the details of the driver (T/S) and box/port parameters?

Hi Bernard, Thanks alot for your help here. This is good to know. I appreciate the feedback. IMO the uploads with these files are slow but should complete on most systems. Claus and I have tested on Windows, Linus and OSX and see slowness but never a crash. However ... I think the killer...

@sm52 I added a downsample option that will reduce the size of the Z-file significantly and make the download less painful. The upload will still be slow but hopefully this will work better for you since the real killer was trying to serve such a large JSON file for download. Let me know if...

@sm52 I don't know that there's much we can do to make this process easier or less painful for such large ZMA files. The dataset is considerably reduced in size before the fit, so one possibility would be for us to add the option to apply the data reduction before offering the Z-file for...

@sm52 Your ZMA files appear to be using 122K frequency points! That is on the order of 100X larger than what we are used to dealing with, so it may be stretching your browser memory.

@sm52 I'm sorry you're having instability issues with Speakerbench. As John noted, Speakerbench doesn't require javascript. We use the Dash/Plotly framework to serve the apps via your browser, so it should work on your phone, tablet or PC without any special libraries or apps. One thing I can...

Very good. Thanks for using Speakerbench, and thank alot to John for facilitating it.

Yes, this is much better. Should be fine for modeling purposes. What did you do differently?

In diagnosing what went wrong, I find the "Model Test" tab to be the most revealing (see attached image). Here you can see that the model describes the unweighted driver impedance well, but does poorly on the 20g and 40g measurements. My suggestions would be to reduce the masses (as John...
