Sorry, the only polar measurements I would have is for the full loudspeaker with the H290 radial horn in it. And those were over-written by the measurements of the newer models with the H290C OSEC waveguide.
I have a lot of on-axis measurements of that old radial horn with various drivers but none with off-axis plots or polars.
