Dear Wayne,
a while ago I acquired some Eminence H290B horns when they were on sale. I wonder whether you can provide measurements of them with i.e. B&C DE250 as a polar plot and SPL off-axis? I figured you could still have them on your hard disk from before when you transitioned to your own creation H290C.
Best regards
Marinus

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.

Too bad. Thank you! If you find some old charts some time, maybe write me a PM.
