Here's a short video with all content including woodwork created by John Lapaire of what the mic hears going from on to off horizontal axis on an Eminence Alpha 8 for:bare speaker; scaled EON style lens and truncated Karlson lens.
I hope it plays as John's choice of music brought up copyright issues.
With some cases, EQ could be helpful as coud be rising on-axis response.
