Good to see a relatively 'meh' speaker compared to the JBL
@amirm. Shows how much you can tell just by these masurements. Took all of a few seconds, before even reading your listening impressions and labelling on the graphs, I thought something like "seems bright, probably sound pretty dull due to the bass suckout and minimal bass extension in the first place. Would probably sound better well off axis." Lo and behold...
Thanks for simplifying the horizontal and vertical graphs! That said, I still think the vertical up and down should be on separate plots or at least different colors- there's no way of telling which lines correspond to which measurement, for instance, and the lobing usually isn't completely symmetrical. This is particularly notable for monitor speakers which will often have a stronger desk reflection than ceiling reflection in many setups, so telling the up and down apart is important. Likewise if you have a low ceiling, you might care more about the ceiling reflection.
For example, here are my vertical measurements measurement of the neumann kh80 I just posted in another thread.

Fairly different responses in both directions. I guess this is evident from the polar graph but those give me a headache =]
I also really liked how you included the ceiling and floor reflection curves in the JBL review - I'd actually take just those two curves over the vertical graphs as currently shown.
Thanks for all your hard work!
