What in the world??? Saw these on @ http://www.partsconnexion.com/CONNEX-76147.html
So just how big a magnet does it take to "levitate" my 80 lb. speakers :)))))

I didn't see a weight rating.  I suspect that there is a narrow range of weights that the magnets will stay in the cylinder without coming out the top or bottoming out.

Ive seen similiar from Clearaudio but at something like $200 EACH  :o   But I think they are made for components, not speakers.  

Edit ... Found them ...  12 lbs each and a whopping savings if you buy 3, only $499 for the 3 set  ;D
If they really do 12 lbs each,  you could probably "levitate" a pretty big floorstander for a couple grand.  Per each.   ;D

I'm sorry guy's, my "timing" must be way off. I really meant this tongue in cheek. Comedy is an ongoing project, like my speakers!!!
Have a great weekend,
John

I took it that way, I couldn't bring myself to buy these or the old Aurios either.  Another Bottlehead told me to try buying 3 dished cabinet knobs and 3 ball bearing balls.  Set the knobs on the shelf and a ball in each.  Then carefully lower my SACD player on top.  The audio cheapskate's Aurio.  I think Aurios have disappeared, but they were all the rage a few years back.

But they dont levitate so what good are they  ;D

Desmond,

The Aurios were concave inside with a ball, so the component kind of floated.  They were just, yet, another device to "isolate" your components.

I know.  I was being sarcastic, thus the use of the emoticon.   ;)

Actually, these things do work as advertised -- just go out and get two sufficiently powerful neodymium magnets and try to push two like poles together and you'll see just how much repulsive force they can muster.  That doesn't justify the prices though, and I happen to be firmly in the camp of drain the vibrational energy out of the component rather than the camp that says to trap it inside with soft feet and isolation devices that isolate the component.

Give it a path to go through and a sink to disperse it.

That said, I do have a magnetic levitating tonearm on my TT.

I know this was all in fun, but these things do work for isolation -- but not on everything and best with things with a fairly even "balance" to the component.  I'd think BH paramour and paramount amps should work nicely with these as they do balance very well .

I'm using some these for my speakers:

I must admit though the magnet idea is attractive, especially for my FP3 and P-mounts. Now I'm learning something about magnets, thanks
for leading me down this path......way cool!
John

PS  here is a pic of a magnet that I have on my fridge that is undoubtedly the strongest I've ever encountered. Anyone recognize where it may be used?

Magnetic is likely from a computer hard drive.

The magnets are used in the voice coil assembly used to move the head in a hard drive. Yea, break pad, for stopping the drive head quickly.

I'll guess it is part of a magnetic clutch -- they are being used more and more frequently in wind turbines these days, but they've been around for a long time.
