"This is our upcoming 1250 RMS line being tested free air with nearly 3x their rated power level -- I took it up a bit too far just as an example =) This was taken with a bit newer camera than previously used -- Canon Powershot Elph 16.1MP. The excursion looks a little weird in this video compared to other videos so not sure which camera I'll keep using in the future -- but hope you all enjoy !" From the video caption.
