The best situation is to have no wall behind the listener. An open concept situation open to the rest of the house. The rear is then open between various rooms. This keeps reflections as late as possible and fractured as much as possible.
Question: Sound Treatment behind the Listener?
I have treated the 1st and 2nd reflection points and I have sound panels between my speakers. I also have tube traps in all 4 corners, but I am not sure what (if any) should be done with the wall behind the listener.
That wall presently has a DIY rack system that holds about 5000-6000 cd’s. I believe it helps scatter the sound. But I’m not sure if that is the right approach.
So, what are you guys using on that wall? Diffusion, Absorbtion, Reflection? Anything else?
I would appreciate your thoughts.
