Thanks for your response!

As long as I know, the tools you mentioned are not made for my purposes
as the room is explicitly included in the measurement, because in the
end speaker AND room is what to be linearized, frequency wise. I need
something different: The speaker itself, in the best case without the
influence of a room surrounded.

Once I used DLSA, a measurement system that could be plugged to the
printing port of (old) windows-PC. There you could configure a time
window to eliminate early reflections of the room. But now, I don't use
windows - and if I did, my laptop doesn't have any printing port. :)

There is JAPA, JAAA and of course "Room EQ Wizard" REW. But I guess,
they can not export any data to create a diagram that fits my needs.
Would be more or less a screenshot solution and I don't know if I could
be happy with that.
