On very thick acoustic foam, on the table maybe a foot from the wall (can't get them any further), a lot of rock wool acoustic panels on that wall.Where do the speakers sit?
Are they mounted flush to the wall, are they on the meter bridge of the desk, are they on a table? Or are they on speaker stands (close or far from a wall)?
And what do you mean by a “dead“ room? That could mean a lot of different things to a lot of different people.
I would be truly surprised if your room is really dead e.g. an anechoic chamber.
