Decoupling monitors are important to avoid sound vibrations from the speakers. If you place your monitors on a desktop or mixer this can produce “comb filtering” or coloration of the sound. Besides mechanical vibration of the speaker contribute to this phenomenon.
Using rigid stands it´s the best option. You have a lot of models in the market. Sound anchords stands work really fine and it´s what I use with my Lipinski speakers.
Monolith is another great stand monitor from Unity audio.
If you have the skill to make your own stands you will find a lot of DIY monitor stands on the net.
When you have to place your monitors on a desktop or mixer you can use 4 smaller foam feet at the bottom corners of the speaker. Sorbothane is a great material for attenuating vibration, like blue dots.
