Clever title eh? 
First of all this is a request to PLEASE not turn this into the usual cr@p! This is a genuine post and I'm after opinions/thoughts/knowledge on ALL sides of this. If you don't like or agree with something that's said, please don't go into personal arsey pants! A bit silly that there's a need to say all this really isn't it?
So........
-----------------------------
To my knowledge the three main types of vibrations are: a) Those produced internally, such as transport and other MOving parts. b) Airborn vibrations, such as those produced by speakers, and c) Those passed into the equipment by whatever it's touching, such as the floor, stand, other equipment etc... These can be from anything such as footsteps to those passed into the floor by speakers and such.
The two main options seem to be to try and decouple/isolate the surfaces as much as possible. Or, to try and give a good coupling.
The use of isolation (such as inner tubes/air bladders etc...) seems like the ideal solution to keep away external vibrations. And, with the likes of amplifiers and such which don't produce internal vibrations it seems the best solution to me. But what about with kit that does vibrate internaly? There's no good route for the vibrations caused by internal MOvin parts to pass on?
The use of spikes for coupling (not isolation as is often said), provides a "ground" route for internally produced vibrations. And on a solid suitable surface seems a good idea. But in MOst cases the surface (suspended floor?) isn't ideal, and this coupling works both ways allowing easy flow of vibrations both in and out of the kit.
So to me, air platforms and such seem the obvious route with kit without moving parts, while for the kit which does it's a bit of a trade off. Isolation, but also some way of passing internal vibrations on.
And then with speakers,(I think this is where I'm trying to get?).
The idea is to keep the cabinet as still as possible and have all the driver energy used effectively rather than having the cabinet being pushed and pulled about. So for that purpose alone, a good coupling to a solid surface seems ideal.
But, there's MOre to it than that yeah? We wish to prevent vibrations from the speakers being passed onto the floor and thus the other kit, and also to avoid a sort of cycle where the sound causes vibrations in the floor which are then fed back into the cabinet. This means isolation from the floor. But using one method seems to go against the other.
In brief, do inner tubes uder speakers work?
How, why and reasons???
Thoughts? Opinions? Knowledge?
Cheers. MO
