Well even taking some arbitrary mid frequency would be better than a wild guess. > > I don't see why adding these values to the sound config > should be such a problem.

I don't see any particular merit is setting the value in preferences.xml, but it would be nice if the default values worked as designed, no matter where they are set. > JFTR: The bo105 sets these values since a while. :-P Well done, but what do you base the values on?
