### ⭐⭐⭐⭐ Good enough. Clarity improved. Dampening increased.
*by A***A on 17 May 2025*

Clarity improved in Home Theater. Avoid 1” get the deepest ones if possible. Installation : Very easy. The hooks on the panel can be easily removed and re-screwed for any adjustments. The hangars are pretty sturdy. Once in place the panels will not move. Rockwool fillings could have been better. And it gets lumped up at the bottom rather evenly staying in place from top to bottom when hanging. Have to compare with others to judge performance. However there is noticeable clarity, less reflections in 7.1 setup. I have 3 of these 2x2 feet on each wall next to the listening position, and a couple of other 2” and diffusers on the back. Its a basic setup without doing every inch of the walls, ceiling. The room now is definitely has more dampening, less reverb without any sound source on. You may have to pair with sound absorption curtain specially for windows etc. 4/5
