4" Carpenter memory foam behide your speakers ???

Schipo I've only tried this on Horn speakers I don't know what effect it will have on other types of speakers.

Schipo I got a new memory foam mattress from Tempflow.com...the new King of memory foam mattresses and I used my other (76" by 60" Size carpenter memory foam mattress topper) to cut up and put behide my speakers. I cut some, about the same size as my vintage Sansui sp-5500 Horn speakers and let it (standed them right on the floor at the wall behide my speakers)...I did not hang it on the wall...(from the front of the foam to the back of the speakers) its about 11 1/2 inches on one side of the speaker and about 8 inches on the other side of the same speaker. It stayed right there too without tipping over.

You can really get the sound to your liking just by moving the foam a little along the wall....this stuff is a Horn speaker's best friend!...
