Absorption/Diffraction..1st reflective points...

14`w by 17`long by 8`h. DL room. I would go with absorption with the size of the room being rather small but not tiny.. Diffraction works well when listening chair is further away from a rear wall.The closer the listening chair to the rear wall the better to use absorption..there is much to read and there is allot of different opinions. The best thing to remember is to use 4" or better. And a little will go along way.The best to you...

I love plants , but honestly I don't think they make much difference in helping to tune a room . As far as diffraction verses absorption , most pro tune company's don't recommend diffraction because it scatters sound waves rather than treating them . Diffraction can make a room sound more like a hall if thats what your into .

I wonder how cork glued on plywood would work for absorption?
