Correct me if Im wrong but-
If you built a cube shaped, sealed, dual opposed sub -and placed it in the center of a room with a perfectly square layout, and at a height that puts it exactly equidistant between the floor and ceiling with the drivers facing up and down- all standing waves would cancel themselves out giving secondary reflections only once. similar to being in an anechoic chamber (with the exception of one reflection).
And it wouldn't matter (or atleast make much difference) where you stood in the room either.
thoughts?

An anechoic room is similar to free space.
Your thought experiment room is not similar to an anechoic room in any way.
It is possible for cancellation to fairly heavy in a cubical room at one frequency dependent on the room dimensions.
If the room was spherical, rather than cubical, that single cancellation would be deeper than in a cube, which has 8 corners further away than the center of the sides, resulting in different reflected distance/time even from a centrally located omni sub.
