Yes they can.
When one learns how to think three dimensionally or spatially, they can see what's going on in a room as plain as one's hand in front of their face. Example, as long as one knows the rules and what the variables are, complex math equations are easy. That sort of thing.
The first trick is to know it can be done. Until then it seems impossible.
I have few talents but one of my talents is the ability to see and think three dimensionally and it gets old people telling me I can't do what I can do, all day long.
Open a wall up and the standing waves are immediately redirected. It's an option that most don't think of.
We can spend many thousands on extra subwoofers, sound panels and EQ solutions when for a few hundred dollars in materials, a wall (even if load bearing), if aesthetically possible, can simply be opened up. One should never discount the possibilities nor should those who think differently be discouraged with ridicule due to another's inability to understand.
Before knocking what I have to post, how about exploring the possibilities?
