It's not just about resonances. Perfect symmetry for walls is vital for balanced reflections. Professional spaces use non parallel walls and a rising ceiling.
non parallel walls in listening room
I have the chance to build a listening room about 16' x 30'. I'll be setting up my 2 channel along the short side and listening towards the middle/back. I can make the 30' wall non-parallel. My question is exactly non-parallel does one need to reduce resonances? Are we talking a degree or so, or a few inches along the whole length, or a couple feet?? Anything more than a few inches would be hard for me to do and I wonder if a small amount would make a difference.
Any thoughts would be greatly appreciated.
