Behind speakers is usually to clean bass reflections. But this means panels must be THICK (2" and up) and/or use cylindrical traps in corners
Absorption behind components and speakers rationale?
I get that absorption panels are used to absorb the first reflection and limit reverberations is a good idea. And a rug and maybe some additional panels help absorb Rogue Sonic waves.
But what's the rationale for including absorption panels behind the system. I have a window door behind my system and maybe this is impacting things in a negative way.
Just looking for a simple easy to understand rationale because not very smart.
