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.

I thought all the internal bracing and rigidness of the speaker cabinets was supposed to be vibration Control.  And now you need to do something additional outside of the speaker cabinet Beyond the feet?  Isn't this kind of redundant.

If you put vibration Devices at the base of your speakers, are you honestly telling me you can hear the 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.

 

Is vibration a two-way street?

So you have vibration from a speaker cabinet, but don't you also have vibration due to the sound waves bouncing around the room where the floor will vibrate and that vibration will transfer back into the speaker cabinet and also the component rack?

So maybe isolation is the answer?

I looked at your system and it appears you’re using the two channel McIntosh for one set of sneakers and monos for the other two. Have you ever tried biampin thing with the MC 275 for the mid/upper range drivers, and the monos for the bass.

You should provide details for the rest of your system. The rack you have is really nice that wood is awesome. Love the casters and they're carrying quite a load.

Do you know the acoustical tiles people put in their ceilings, and on the wall. They’re about three or four dollars for one square foot piece.

These are excellent absorption panels and they fit real nicely underneath certain speakers and other components. And what’s really cool about them is that you can easily slide the component around, and the speakers can slide a around to if the footprint isn’t too large.

How’s that for solving the vibration problem?

Mr. @audiopoint

Thank you for all your comments. It would be of interest to see your system and how it’s configured with all this vibration stuff but I don’t see anything there.

It would be nice to see something on your system thanks
