Don’t know if these count.
The first time I watched “Master and Commander” during the opening battle scene I thought I heard a couple people running across the roof of the apartment. Thinking they might be firefighters I jumped up to look out the door only then to realize it was coming from the speakers.
The first time I calibrated the speakers I set the EP500 volume at the 9:00 position. As the test tone dropped lower windows, dishes and the TV started to shake and rattle. I thought I heard one of the kids in the neighboring apartment yell “terremoto.” I confirmed with my fathers cleaning lady that it meant earthquake.
