I have ProAc One SCs mounted on Atlantis stands. I have a foam rubber mat, about 4x5", between speaker and stand. I have been reading about different ways to connect the speakers and stands. The Fat Dots decouple. Blue tac couples solidly (supposedly).

What happens with decoupling; why is it good? What happens with coupling (some companies make the stand fixed to the speaker)?

What effects does each have on the sound? Which is better?

Thanks

Hi, Jim. I recommend a set of four Square Fat Dots between each speaker and stand. A decoupling/isolation approach will bring out the best potential of the speakers, bringing out a more natural sonic result that's more faithful to the recorded event. Foam rubber, however, will not give an ideal result, because it's too slow interacting with very high-frequency acute vibrations that cause a lot of glare and grunge and foam rubber tends to introduce its own lower-frequency resonances into the vibrational environment.

The topic has been brought up before on this Circle, here:
