Audio Supports

4 of a kind beats 3 of a kind,as Buconero says.

Mceljo is correct in theory, but I find 4 easier to level.

In my experiments 3 always sounds substantially better than 4, more grounded. Unless you go round with a stethscope and dial in the spikes precisely then 4 is less stable. It always amazes me when designers claim they make the ultimate product, cost no object, and put 4 feet on their gear shows they dont listen.

I didn't know designers who use four feet on thier products are stupid... Seems all is right in the world of three footers.. As usual, everyone else is wrong. Standard Audiophile ideation.
"I" know the true secret, and you are all wrong.... sort of stuff.
Actually I am laughing at you as much as you are at me.
So we have another audiophool stalemate.
It joins the:
All wires are the same/ wires make a difference ... and all sorts of other audiophool dilemmas which are pretty much the new "How many angles can dance on the head of a pin." quandry.
I guess we can agree to differ.

Angels.. angels can dance... not angles.. LOL
Maybe angles can dance.. Who knows?

It has to do with the center of gravity and the distance to the support points. If you have a speaker with a square foot print with four points of support at the corners, the center of gravity is equidistant to any two points that you tilt against. If you had three points on that speaker (two in the front, one in the center rear) and you tilted against any two points, the center of gravity is still equidistant but closer to those two points than the four point speaker. Meaning, that the three point speaker will topple over sooner than the four point.

A three legged stool is more stable than a four legged stool because a four legged stool only needs three points of support and those three corner points are not equidistant from each other, hence it tilts easier than a three legged stool which has the three legs equidistant from each other. However... it is easier to fall over if you tilt back on a three legged stool because of the center of gravity is closer to the two tilting points. The same tilting distance on a four legged stool will send you safely forward since the center of gravity is further away from the tilting plane.

A long winded way of saying any more than three points of support on a stool makes it easier to tilt back but harder to fall over.
