Coupling/De coupling Query

[icehockeyboy]

Like a few others in the UK, I thought laminate flooring was good ( at the time!)
and I am wondering (again) what others have done either coupling via spikes, or using Blu Tak or something similar.

What were the results? :)

Sorry for my ignorance, but what do you mean by 'decoupling'?

Do you mean isolation or is it more specific?

I thought spikes (in my understanding of coupling/decouping) would be 'coupling' by a direct physical contact of two non-compliant materials..

Have a search through RS's feet and isolation products too before spending on price-inflated HiFi marketed products.

Oops! Having re worded what I put originally, I left that the wrong way round, yes, I meant coupled re "spiking" :oops:

Although having said that, due to the tiny area of spike to laminate floor contact, it really is more like de coupling rather than the effect it would have they were going through carpet and underlay into a wooden floor....dontcha think......?

As it stands at the moment, that is how I have them.

Not sure about that..

Them going through the carpet to the wood floor wouldn't be much different to the laminate anyway (I thought this was the original reason for them).

How much a small area of contact lessens vibration transmission I've no idea and slightly sceptical - it must depend on the type and plane of the vibration.

You can certainly make a surface sing by touching the end of a tuning fork onto a surface and that's not much contact area..

With a solid contact between two surfaces of different acoustic impedance, you also get a reflection coming back into the stand or speaker.

A compliant material that turns vibration into heat or single, controllable mode/frequency might be best - bluetac should be good in theory in this sense. Then the vibration is taken away, turned into another energy.

But then you end up with bouncy, wobbly stands! And that to many in itself seems counter intuitive (although not to people like Max Townshend).

l too use these on the dreaded laminate flooring, they are superb at what they do, will improve the bass alot, you can move the speaker around easily( if you have to), well made and good VFM:)
