You know, another approach is to put absorbent panels to the sides of the TV, as well as making sure the floor between and behind the speakers have absorption.
Acoustics aren't all linear. A lot of it is more about the duration of sounds, so if you can't directly address a problem (like making the TV screen absorbent) you can compensate in other indirect areas.
