Q & A for the ATS Acoustic Panel - 24 x 48 x 4
Can I install these panels across a corner?
Yes, if you choose the open-back option and you are interesting in maximizing low frequency absorption, you may choose to install some or all of your panels across a corner. We have a unique corner installation kit that makes it easy. For details see our corner installation instructions (PDF).

These are pictures of my home theater room. I used five 24" x 36" ATS Acoustic panels- three on the back wall and two on the side wall. Thanks!
