Final Notes:

Decent directivity performance in the horizontal axis, close to the rated 60 degrees for the top two octaves but widens a little below that. Vertical coverage is a little more uneven gradually narrowing from ~90 degrees at 2 kHz towards the rated 40 degrees around 12-15 kHz just before flaring out again to ~60 degrees up to 20 kHz.
