DIY Leslie!

Another very wierd experiment:
I used a cheap "hifi" speaker cabinet, mounted a hook at the top and then
lifted the whole thing up with a string so the speaker was hanging down from
the ceiling. I used thin, flexible cables and so the thing could be "loaded"
just by spinning it by hand. If the string is pretty good twisted: release it
and it will spin. Of course this is only an experiment, the motion will stop
and then the speaker will spin into the other direction, so no "real" rotor
cabinet effekt.  

But would it be such a stupid idea to use a wooden frame to hang the
speaker into (instead of ceiling) and a use the kind of motor that is
used for those disco mirror globes. Or some other kind of motor? Some
kind of sliding contact mechanism is needed to avoid twisting of the
speaker cable, some construction kits (Fischer Technik, not only for
kids, have such elements).

Advantage:
-cheap, buy a "hifi" speaker
-low noise: the string (maybe rubber string) will damp all motor noise,
 no bearings that could propagate mechanical noise to the frame or cabinet

Disadvantage:
-flimsy construction, only for lightweight speakers
-maybe dangerous at high rotation speed
-sliding contacts may produce electrical noise
-No bass horn, effect will be no good for bass
