OK, good point about the aixs. That does exaggerate things. The different actual values is what really threw me off. Plus the values were not off by the SPL correction values, so I figured something else was going on.

I will redo my filters, not applying C-weighting on import, because I have double corrected my values to generate my filters.

So, in the future, if collecting real time readings through REW, I must use the correct cal file for my SPL meter - so that REW corrects them properly?

I will post updated graphs after I redo my filters with the correct data.

Thanks!
