Acepunch 36 Pack Bass Trap Acoustic Foam Panel DIY Design Studio Soundproofing Wall Tiles Sound Insulation with Free Mounting Tabs 4.7" X 4.7" X 9.4" Black AP1133

I wasn't satisfied with this product as it had bad chemical smell. I had to return it as it's probably toxic.

Lets be honest.. It is not crazy for this amount of money.. They do the job acoustically but in terms of eyelook they don't do their job.. They are not even when you put them together in paralel.. so what's the point.. if you are gonna put them separately they will stay in whatever form they want. But overall they are fine!

Includes 3M double tape for added convenience and neatly packed compressed foam that works wonders to expand considerably.

I really appreciate the fast shipping and delivery of the product. Best buy actually for the price. Keep it up Acepunch! Thank you.

Easy to use & effective

Muy chiquitas .... no sirven

This is a very cost effective bass trap, this improved the imaging, I’m planning to get some more panels to tackle other issues.

The only reason it's not 5 stars is purely aesthetic. It's impossible to stick these in a corner and have them line up correctly end-to-end. My OCD kills me every time I look at them because the ends aren't quite perfectly aligned. However, they did kill the corners just like I hoped and vastly improved the sound of my system.

The size makes it versatile to trap those pesky corners where a wall meets duct buildout or, in our case, areas of our whisperroom where we combined them with other treatment materials.

Rather small and flimsy, not sure they are doing much.
