Vibration isolation or absorption?


You see those pointy things at the bottom of a speaker that are very very sharp.  Arguably a weapon in the wrong hands.  And then you see those same pointy things inserted into a disk.

So the pointy things, aka ‘spikes’ , can Channel vibration elsewhere and away from the components and speakers, or they can isolate it.

Seems channeling vibration away from a component/ speaker, which I guess is absorption, is preferable.

Is this true? And why do they keep saying isolation.

It’s amazing how that if a bunch of people believe that it’s not true then I guess it’s not true??? !! When I first came on this forum, I got into it with millercarbon about this exact same thing. Except I couldn’t explain it as good as the fellow above. He really did a good job explaining how it all works. Somewhere inside of me I knew it didn’t work from my sixth grade science class. I wonder how much other stuff in audio that everybody thinks is truth will turn out to be false in a future ?   I guess I better sell my stock in still points.

Last year I broke down and bought two sets of Isoacoustics Gaia Ones for my KEF, Reference Five speakers and the difference between the spikes and the Gaia’s was night and day spectacular.  I put some pucks from the same company under my DAC and heard nothing.  I put some pucks from the same company under my amp and maybe I heard a difference.  

So much information herein.

I had come to believe that vibration that contaminates a drivers performance is not good. So if you’re speaker cabinet is vibrating and detrimentally impacts the drivers it makes sense this is not a good thing. So don’t you want to draw that vibration away and channel it somehow into a bottomless pit. Shouldn’t the pointy things, aKA spikes, funnel the vibration onto A disc pucky thing that will make the vibration go away.

Why would you want to isolate vibration and have a rebound back-and-forth all over the place within a speaker, or component?

I’m not sure that simple concept is discussed anywhere herein that I saw.

 

Many engineers, supposedly the arch enemies of audiophiles, identify springs as the best form of vibration control. I use springs exclusively on amps, CD players etc with good effect but have yet to find springs to use on speakers as they render floorstanders unstable.
