"...I have no choice about speaker placement..."
That might limit your available choices for best sound. For a hearing loss, there are things you can do. I have a single sided hearing loss. So I slide over to hindered side and turn my good ear towards the center. A few years ago it was a minor adjustment but now it's a real big one. I don't use a balance control, I feel that messes up the way the speakers work and it makes it worse. Position of the listener works best.
