2 PCS Black Foam Padding - 16x12x1 Inch High Density Polyurethane Sheet, Cuttable Pad for Packing Cases, Cushioning Inserts and Crafts

I bought a TV from Amazon. The speakers are in the bottom of the unit facing straight down. I have a Quartz countertop so the sound bounces off the counter top then off the wall and it echo's like crazy. I cut some of this foam and packed it tight up against the speakers. No more echo. I have enough foam left to do about 10 TV's the same size.

One inch isn't the thickest and there aren't many applications for stuff this thin, but for MY project it was perfect. It arrives in a vacuum pack, so give it time to expand on its own when you open it before putting to use. Clean and durable. Responds to Xacto knife cutting very well.

Dense good quality

Did the job , behind that black thing is a glass, since the house was old they have those old school style rooms , so basically people can tell from outside if Im home etcs , so I bought it to cover the glass not to mention it lessens the noise too

The measurements were accurate. I wouldn’t call it high density. I was looking for something closer to flip-flop bottoms. This is closer to light weight upholstery foam when it expands. It will wear out fast, so I will use it for now and keep shopping.
