I'm putting a speaker on a metal filing cabinet- it's either that or move
the walls.  
 
Anyone have experience taming this beast so it doesn't add unwanted bass
coloration.  Anyone have experience wityh this problem?
 
I'm contemplating putting on a butcher block for density and heavy rug
underlay below it, the speaker on top.  It's a bookshelf B&W.  
 
Amy practical suggestions welcome.  I've already ruled out hanging it from
the cieling, suspending it from helium baloons, etc.
