Happy Holidays! During Thanksgiving we had guests staying over. I dragged out a 3" thick memory foam king size mattress topper that we stopped using and put it on the living room floor for the kids to sleep on. After they left, with the topper still on the floor I had a listening session and was amazed at the improvement in soundstage. The floor in this room is tile with a thin throw rug in the center. I knew that it was an acoustic problem but really had no options given it is the family room. I did some research on the type of foam that is used and determined it is closed cell which is not ideal but can improve low frequency. There was no arguing with the improvement it made. I cut the topper in half so I can roll it up and put it away easily but can toss them back in there when I have the house to myself and want to do a long listening session. I stack one on top of the other for 6" thick. At some point I will probably get out the microphone and take a measurement of the room to see if the change is measurable.
