Am I crazy????? Try THIS

Eldartford...I hear you. There is one thing that i can think of that may have made these 901's move...could it be that these speakers have a port and a burst of air coming out of the port could get them to move?

Eldartford...I am looking forward to your report.

About 30 years ago i remember Boze 901 hanging by chain in a Hi Fi shop and soft classical music was playing. Suddenly there a very loud passage (VAAROMMM), this got them swinging a bit.

gmarcotte@...Do you know if each speaker had two chains going to the ceiling or more. This would make the difference.

Well...i have to tell you; you had me doubting my memory, so i call my friend that was with me at the time when we seen the 901's and he remembers the same thing. It surprised us both and we looked at each other. He recalls the music; it was used in the movie Close Incounters of the Third Kind, where there is silence and then a powerful VAAROMMM. This made them move about 1/2" or so. They were hanging high, maybe 2ft. from the ceiling and 2ft. from the side wall and back wall. I attest, they moved.

Yes...Like a child on a swing.

There is a post or two on this thread that suggested that a speaker could not be moved by music, at least not in a way that could be seen by an observer and i just though i would post what i have seen; that's all. If any read anything more then that in my post, then it is your head, not mine. I have never seen speakers move since then. The 901's have a lot of drivers for there cabinet size, perhaps this why they able to moved so much from this burst of sound, maybe the canon shots in Tchaikovsky 1812 Overture would do the same thing: i don't know. I don't think music could be found that would have the right timeing in pumping action to match your speakers mass that would get then swinging more and more like a child on a swing. I must say, that there is some music that moves me.
