Sorry - I didn't get it - where are the speakers?
The part to get was that the (3) speakers were all located in one spot. The guy OTOH moved from one edge 50 yard line to the middle of the Endzone, without much (any?) perceivable change in the sound level.
At the end of the video he kind of zooms in on the Danley Synergy Horn speakrs, the three side-by-side black boxes in the center of the screen.
That, and it was around 85db where he was, and there were details like the triangle audible. Sure beats my Saddle Dome's crappy P.A. system.
