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.
Since the dispersion at the top octave of 1.4" horns is highly dependent of the design of the phase plug and exit angle of the compression driver used I have begun testing each 1.4" horn with the compression drivers I have. You can find the measurements of this horn with each of the compression drivers below.
