I run this test on my laptop with a demo-version of WINAIRDD.
The titanium dia's are rolling off earlier than the phenolics?
The results were checked on a Klark Teknik real time analyzer with a test microphone, showing the same results, but actually they were readable.
Phenolics -3 to 0 db from 800 to 8000.
Titaniums -4 to +3 db from 800 to 8000. (-5db from 400...).
Tried the signal generator on another software, but with that software the resulting curve was only flat from 1.6K to 4K measuring on the Klark Teknik. Did not have the cables etc. to use the Klark Teknik as a signal source.
