4" Carpenter memory foam behide your speakers ???


I put some 4 inch thick carpenter memory foam on the wall behide my speakers and I'm just AMAZED by the difference I'm hearing now!... The soundstage is so holographic and the sound just wraps around me now...this is highly addictive! Has anyone else tried this yet?

PS the properties of the material make it hard to hang on the wall as the force of gravity might have a tendancy to deform the material over time.
Yes basically that's it. They come in all sizes and also very large style body pillows. I would think that the larger size body type could be made into a very good tube trap.
HiFisoundguy may I ask you to be more specific with your finding. How did you mount them and did you use the memory foam pillows or? How large a foam did you use and placed directly behind speaker or up more towards ceiling.
