Acoustic treatment for radiators -Acoustics Forum-Acoustic Fields Forum

Gray ones that you can see i used in my studio. I replace them with better ones so i decided to put them to a test in my living room/home cinema. They are build from wooden frame, filled with rock wool and covered with microfiber. Rock wool is 8 cm thick so i guess they can absorb 100hz and above, havent tested it. They were used to treat side reflections in my studio and also they were used on rear wall to stop some slap back. The ones that are corner are triangle cut frame, filled with triangle cut rock wool. I guess they perform little better. They were used to prevent build up i corners of the room.

Now, i took them to test how they look in living room but as you can see, radiators cause a big issue. They are placed on different sides of each front corner so in theory you can solve one wall from side reflections but you cant other. I can manage side walls but front reflections next to TV i cant, it will look ugly. Btw, the canvas frames that are shown in YT video is same technology but the cover is canvas.

So to sum up it up : how can i solve the first reflection problem of front speakers bouncing off from front wall that looks nice and neat and matches the room interior. Do i move the speakers or something else ? I can deal with side walls, one canvas filled with rockwool is placed behind the couch (left speaker) and right speaker is treated with absorber behind curtain. And also, how much surface of canvas i need to use.

Speaker freq response is 70hz to 18k. They are build to add extra sub
