Hi,
1) What is the directivity of curved speakers like these?

Cadence Anina Loudspeakers [English]
2) Does anyone have polar plots of these? They are very similar to Don Keele's CBT without shading and are dipole instead of monopole.
Thanks and Regards,

A few observations, they are curved horizontally, so
1) When we see them from high freqs to somewhere in the mids, lets say frequency x (which corresponds to the width of the driver), they are dipolar, they are essentially constant directivity, their beam angle determined by the curve. Its front and rear radiation will be symmetrical. It behaves more or less as a CBT, without shading
2) Below the frequency x the horizontal width can no longer have its own beam and the beam widens, so the driver becomes a dipole. The impact of curve is not clear in this frequency region. Its beam will not be symmetrical, it looks like, its front beam will be wider and rear beam narrower.
3) Vertically, its a very short array, there is no curve to provide delay, its beam changes with distance and frequency but that is of very little consequence/detriment since the array is too short.

Nice looking speakers.
Beaming is horrible in the usual textbook "plan" view. But there is no such thing as "beaming" from the worm's eye view (AKA in "elevation"). You don't get "beamed" you just get more brightness or more probably, you just get the right amount.
Having lived with ESLs with just that sort of arc, and esp. as dipoles as the previous post mentions, I'd say they are just honky-dory as for dispersion.
