UMIACOUSTICS 6 Packs Acoustic Panel,48 x 24 x 0.4 Inches Sound Absorbing Door Panel,Decorative Wall Panels Equidistant Slot for Room,Home Theater,Studio

For the price, these are great! I've put them in my studio/mix room to control the reflections off hard walls and they're doing an excellent job. With sloped ceilings and limited space, I didn't have the option to install 2" thick panels 2" off the wall but these are unobtrusive and easily fit in my space. I screwed them to the wall using DeWalt 'Wall Dog' plasterboard screws which are holding well. I also installed them with the smooth side (back) visible as the stripes are a bit much! Of course they won't do much for low end/midrange acoustic issues but for flutter echoes they work a treat. They're also easy to cut down if you need different sizes. Would recommend & buy again.

A great option for the price. It takes the hollowness out of an office

I installed them and they work as they should for thinner walls you might need 2 tho.

I built a recording studio for our podcast and the panels work great and look great! Even without 100% surface coverage, there is little to no reverberation in the room now - you can literally hear the difference just walking into the space. I hung the panels coated drywall screws because I didn't want to deal with tape failing on me.

I placed an order for two packs of 6 but only one arrived and the second was at first delayed, then placed on backorder. Given that I was simply expecting them to be delayed, I hung up the ones I got and now my space is only halfway treated. So, decent product but not great logistics which is a concern given that you’ll mostly likely need more than 1 pack of 6. Still waiting for the remaining order to be fulfilled.
