Additional Notes:
Chinese Clone of the B&C ME90.
It's a poor clone, in fact the general dimensions and a 1.4" throat are the only real resemblance to the ME90.
This horn is symmetrical even though it lists 80x60 dispersion likely just scraping info from the B&C. The profile and throat are quite different from a real B&C ME90.
Since this horn is symmetrical I only tested it on one axis.

Mic distance 1m, measurements gated at 5ms and are smoothed at 1/48 Octave.

Final Notes:
Dispersion more uneven then the real ME90, possibly about 80 degrees nominal. Stronger waistbanding just below 2 kHz then the real ME90, a bit wider in the 3-5kHz range and slightly narrower above that.
Top octave dispersion is determined largely by driver design and throat match-up in the 1.4" realm.
