Isn't this accomplishing the same thing as a 3 x 5 diffuser panel?
And also providing way to sneak a diffuser past the SO (significant other) 😎
I am thinking about some veneer/laminated fish or manta rays, to hang on a macrame type of hanging.
(The SO wants to have some ocean wave type of macrame wall hanging behind the sofa, and I suggested some ~250mm square folded manta ray looking pieces to put onto it… she said, “Would you do that for me?”)
Basically anything moving away from glass and polished marble is a good direction, and if one likes books, then bookshelves are a very nice option to make a room comfortable and also sound good.
