I can say that you should not just follow the "Hifi Golden Rule" from Hifi forum. e.g. Your worker is hard to determine the inside width. They always think about the outside edge width. The wall material have width also. Tell your worker about this to subtract this size if you are too concern about this HiFi rule. The Hifi sound is related to what kind of wall material also. I pm my telephone to you. Tell deeper.
