Construction
These 6' lengths of foam come in a variety of of shapes and colors, but are basically 3" in diameter. They were verywhere this past summer (2002) and were a hit with kids. They are made of flexible closed-cell foam and can be cheaply cut into many shapes. They can take quite a bit of weight without collapsing. I have 135lbs of speakers over two 20" sections and the foam is still two-thirds of its original shape.
 
Setup
Heat up a knife and slice throufh the material. The air cells will be sealed this way.
 
Use
They can be used under speaker cabinets or components to damp and isolate. I suspect you'll come up with some good ideas of your own once you see how uit's constructed.
 
Performance
Nearly as good as expensive commercial preparations. DRAMATICALLY reduces bass boominess. After using this, decorative plates in my dining room stopped rattling or falling off the walls. 16Hz - 50Hz bass became clearer while mid-bass resonances were nearly all eliminated.
 
Other
Colors can be quite garrish in your listening room. I settled on deep navy and dark purple. However, it's easily camouflaged or colored with markers.
