What is the purpose of building the support in L shape? What makes it better that having the piece of wood parallel (side by side) to each other?
I want to build a false wall for a screen that is not AT and the speakers will not be hidden behind it. It is a 2.35:1 120" Wison Art DIY. Any suggestions for the wall will be appreciated.
In case someone ask, why build a false wall? Because I want the speaker to have some space to breath and to put OC703 on the real wall.
