2"×12"×12" High-Density Triangular Acoustic Panels (12 Pack, Flame Retardant, Sound Absorbing)

I use alien tape to install on wall. The panels are of good quality the 2". The color is very nice.

The material is thin thus it wont deaden sound, but it’s certainly better than nothing. I use this in conjunction with custom built absorbing panels and these serve as great compliments, especially given the size of my small studio. Love the color and design as well. It is very much used functionally as it is aesthetically. It fluffs up to its full volume in about a day after removal from the vacuum sealed packaging.

Works but u can find better. U need some serious gorilla glue fornthese

I purchased 12 panels for speaker boxes I was building. I built the boxes with the dimensions of theses panels in mind. The insulation came in two vacuum sealed bags with 6 panels each. They were very compressed, maybe 1/2" tall for 6 panels 2" in height, so 12" to 1/2" compressed. I left the panels out overnight to let them expand, but none ever reached the 2" height they advertised, several sections barely reached 1". The tallest any of them got to was @1 3/4". The height of the sound insulation plays a big roll in it's affectiveness to stop distortion, so not meeting or exceeding the 2" is an issue.
