suspending monitors from the ceiling

Wonka's experiment is not the only one.  It's pure and simple physics. 

Of course, a lot of things come into play.  The location of the driver, the volume, the mass of the speaker, and the location of the driver relative to the stand.  Tall, skinny, lightweight speakers with drivers waaaay up high are going to have more of a problem than super heavy, and inert speakers with big woofers next to the floor.

I have seen Dr. Floyd Toole Revel Salon 2 floor standing speakers hung from his ceiling, I kidd you not. 
N.B.  He is the author of Sound Reproduction Loudspeakers and Room. 

Proper positioning may take some precise and pia experimentation. 

We played around with this stuff back in the 70's.  We used a garage door opener to lift them up when we weren't listening.  We thought they sounded good.  (home made speakers by kids with passion and really good tools).

Scott22, I have done it. They were 2 way open baffle speakers using Focal drivers. I crossed over to subwoofers ar 100 hz. The speakers are hung from a very sturdy beam using two chains per speaker. The tweeters are at ear level.  The owner is a high school music teacher. He loves it and for what we spent on the system it is killer. The only kicker is I would not want the speaker making bass even if it is fairly heavy.
