Best room treatment
Good day everyone. While I’m waiting for my system to arrive I’m turning my attention to treating our not so good 2 story family room that it will be installed in. There are quite a few brands out there. My question is can anyone who has tried the various brands recommend the ones that work the best for absorption and diffusion. Thank you
