Speakers on speaker stands-isolation ideas?


I have some mid sized book shelf speakers that I use on 24” high speaker stands. I’m looking for sway to best isolate the speaker and or stand from vibrations.

The current speaker stands are filled with play sand and I have blue tack underneath the speaker holding them on the stands. The stands are located on an upstairs bonus room with carpet and foam padding underneath. 

Anyone recommend some ideas for better isolation for this kind of setup?

I put some self-stick felt pads on the top of the stands, under the four corners of the bottom of the speakers, that seems to work well...in addition to filling the stand's upright with sand.
+1 Chayro There are different types of ’isolation’. Some use the term ’vibration control’. Search the Audiogon forum archives for ’coupling’ vs ’de-coupling’. Experimenting with each will provide the solution that works best for you. Clarity suffered when using Blu-tack under my monitors on Sound Anchor stands.
I like these Acoustech Speaker Dots:

They’re the Sorbothane pucks that come standard with Sound Anchor stands. I’ve found nothing that "sounds" better.
