Run REW (Room EQ Wizard) or the equivalent and find out what your room really does.
You may be lucky and have a listening position that is accidentally perfect. My daughters bedroom is like that.
All it needed was some bass absorption on the floor (provided by two 2.5’X2.5’ 8" inch panels just placed on the ground about 3 inches from the wall behind her subs and speakers (some BW 701s and equivalent BW subs). She literally has a perfectly testing system for dispersion/standing waves/pressure -- the whole thing -- at her listening area with zero effort. It happens.
My actual listening room (a literal bomb shelter; not joking) was not so easy and had awful echos, dead areas, and all sorts of weird stuff that required a lot of both testing and treatment.
