Ok I bought some sanus metal speaker stands for my mini monitors. Now When I put my mini on the stands what can i do to prevent them from moving on the stands. My stand has 4 holes but did not come with any screws to prevent the seaker from sliding the dealer told me to get double sided velcro at home depot. He said that this would prevent the speaker from moving. Also the top plate is 61/2 by 6 and the mini monitor speaker is 8 witdh by 12 inches long .. since the mini monitor is a big long speaker will i have a problem with these stands. All the stands that i saw had basically the same top plate.
