These were purchased to surround the movie screen area and are not the primary source for absorption. I built acoustic boards and ceiling to floor bass traps as my primary acoustic and absorption control. For the purpose of which I bought them, they work wonderfully. They absorb the light around the screen excellently, and since I have bi-polar speakers, the back side of the towers needed only a touch of sound treatment around the screen wall.

Didn’t buy these for actual absorbency, but something cool to put on the walls of my boyfriends gaming closet.

Got a roommate who games all night and gets LOUD. Spent $65 on these thick panels and a pile of 3M double sided sticky mounts and haven't heard a thing since

Will probably buy more to use in between storm windows and outter windows in my bedroom. I think this product would be ideal for that purpose due to its "fluffy" nature, in reducing noise coming through the glass, as well as tighten them up to reduce "rattle" with large or close thunder.

All exactly square, and same thickness, and actually thicker than I expected. I used all purpose glue spray to stick them to the walls as there’s no paint in the closet so rip up.

They stuck very well and didn’t try to shrink or anything. Very easy to cut as I had to size a few to go around shelf and line up on the wall properly. Overall I’d say a very good bang for your buck if you just want some cool wall decor, the sound absorbency is amazing as you’d expect for the price. Very good!

They were exactly as I ordered and were exactly what I was looking for. Got here very fast

It’s amazing how these panels are compressed for shipment and they expand when you open the packages. We used Liquid Nails to secure them to our concrete walls and can really hear the sound difference. They surely help to stop the reflection.
