Not sure I like those gik diffuser panels, don't like the way they look.
I don't think anyone really knows what they're using and why. Some say use diffusers behind the speakers and some say use absorbers and for those who lack conviction, use a combo deal.
Truth is many rooms may not need acoustical treatment due to all the furniture, and pictures in the room already, which serve as diffusers.
Unless you're using diffusers in a large area in the room, most often they are probably a waste of time.
The biggest challenge people tend not to focus on is what the hell you do with a ceiling. A wide open flat space the tends to be problematic, incredibly difficult to mount panels on.. Who wants to put holes in their ceilings?
I'll put up a few absorption panels, behind speaker and at first reflection points and call it a day. I guess first reflection points are a bad thing. As Sound waves spread from a speaker the first reflection point is fairly big.
if I ever see a diffuser panel thats unique and really nice looking I'll get it.
