Important point. No, this isn’t how Klippel works. In fact Klippel is capable of creating exactly what you demand. It solves the PDEs based upon the measurements taken and determined the actual radiating sound wave at each location in space. Of all the measurement systems around it is probably the only one capable of determining what a panel speaker is doing.Although Amirm uses multiple averaged measurements across the panel dimensio
Where there is room for more work is in making use of the sound field projections. No doubt, a panel is a different beast and the manner in which it interacts with the room much more complicated than a box speaker.
There is a lot of talking past one another going on here. Everyone knew the first time a panel was measured fur was going to fly. It was a given from the outset that any dipole was not going to fit the standard mould. There is a lot happening here. Linkwitz wrote a considerable amount about this and the nature of how the speakers work in a room. He was no fool. Olive knew Linkwitz and his work, and was always full of praise for his efforts. I think he appreciated that there was much more to learn.
