I read a lot of things written here as if they are gospel. I will give you my own experience.
Gospel? No. Physical reality yes.
If your speakers are two feet from the wall it's easy to calculate where you will have a null in the frequency response.
Sans room treatment it's a given echos front and back, sides may not be too bad given size and placement.
Speakers at 2 feet, 10 feet apart listening at about 12? ... Some bass nodes at play.
Room correction?
You may very well enjoy your system but is the soundstage real or echo? Is it ideal? No.
