Subject:OT - Moving Air

In a recent discussion about Leslies and loudspeakers, it was stated that all speakers move air. With loudspeakers, I'm not sure if the air is moving or if it is just the moving wave in the static air. I don't know if a Leslie makes a wind as does a fan. Yet, PLEASE CHECK OUT THE FIRST PART OF THIS VIDEO showing a wave in action. (As I did, you may get off on the following philosophical discussion, tho' this is already really way off topic :)
