Mark Audio Alpair 7MS off axis measurements?

Howdy folks. I've been looking around at the Alpair 7MS driver, and it seems like quite a nice driver.

I'm wondering if anyone has taken any off axis measurements, because Mark Audio as far as I can tell does not provide any. I am assuming the dispersion is quite good, but I haven't really been able to find much info. Can anyone help me (and others looking) out? Thanks!
 
There are few Japanese people who like Alpair7MS.
Why is that? I do not know.
