He does, indeed.
Just to clarify a bit: As stated in the video, Erin talked with Andrew Jones and the latter said that the SourcePoint has been specifically designed to perform slightly Off-Axis. Whatever some would or wouldn't be OK with that,
Erin provided the full data for several cases, anyway:
Straight On-Axis:
10° Off-Axis (recommended by the designer):
30° Off-Axis, jut in case...
Better having more data than not enough in my book. It isn't like something would be hidden whatsoever. AFAIC, I just think that the
horizontal directivity plot could be updated, as it should be presented at 0° for a more intuitive reading.
Apart from that, great and extensive review as usual.
