TroyStudio Self-adhesive Acoustic Foam Panels, 12 X 12 X 2 Inches 6 Pcs Broadband Sound Absorbing Foam, Dense Soundproof Padding Tile, Recording Studio Foam Absorber, Groove Decorative Wall Panel

OK, so cons first;even after unpacking and waiting 72 hours for foam to expand, some units had malformed/wonky edges.Adhesive coating was a little shy of the borders so there is a 1/2 inch or so around the perimeter with no stickum.Pros;cheap. Easy to cut and apply. Much more effective as a bass-trap than I expected. Canceled out most of the low frequency standing wave problem in my listening room with only 18 squares.

Mi vecino hacia mucho ruido con la TV. No quita del todo el sonido. Sólo se oye como un susurro muy leve. Genial para mi.

Wow these are junk and not even close to being 2 inches thick as described. You have to soak them in water to get them to expand and then dry all of them with a hair dryer. I’m sure water and heat will be great on the adhesive backing. Returned.

Love em!!

They work great and unlike other acoustic foam, they actually inflate properly to their normal size.I wish they had more colors in this style of foam, but this one pack of 6 seems to be the last. :/

Arrived earlier than expected but they reek. What chemicals are in them. Can't even use them they smell bad even after washing! Set off asthma and allergies. Don't waste your money here.
