You are right that advice varies a lot. I have heard the same advice you give. But in practice it has never worked for me.steevio wrote:i'll have to dig it out but i read an article in which it advised to use the long wall of a rectangular room for your speakers, the opposite of what it says there.
also ive been in lots of control rooms of studios and mastering rooms, and ive yet to be in one which was the shape in this diagram, they are almost invariably wider than they are long.
i had my studio length ways to start with and it was terrible acoustically, as soon as i turned it round it was much better.
i think you have to experiment to get it right, read as many different articles about it as you can, you'll find advice varies alot.
I have always thought the facing the length works better if you have a decent amount of space behind you.
