Sorry if I'm a bit slow. I haven't really seen a waterfall plot before. It seems like a really interesting way to map the data. So essentially, what we're seeing is driver response with frequency and volume? So the lines that extend past the rest of the wall (further than so many MS) are ringing resonances? To put it extremely simply, the axis coming towards us is sort of like the impulse response, the axis going from left to right is by frequency, and the axis going up and down is the volume?
