Accoustical panels vs isolation platform


I had a couple extra accoustical tiles which i placed beneath my main speakers.  Seems to me this may be a good idea.  I get about six panels for about 20 bucks. 
 

Anybody else try this?  I understand isolation feet for a subwoofer and A need for rubber feet on main speakersto to avoid vibrating the floor, etc.  But these panels seem to accomplish a lot of things, and now I can slide them around if I want as a bonus.

Try experimenting with the panels on the side walls and back wall to compare

This is interesting I like this idea, isolation platform's are helpful but incredibly overpriced for what they do and there's easy substitutes out there.

The tiles are basically compressed fiber boards and super cheap and you can shape them if you want
