If I were to let my personal biases show about center channel placement, you may achieve a very smooth tonal match by placing an M22 vertically on the floor in front of the TV. The limiting factor here is the floor-bounce effect, which may yield some upper bass emphasis (you'd notice it on male dialogue--a slight warm, wooly coloration). Try tilting the speaker back slightly up towards the listening position to lessen any boundary reinforcement effect from the floor.
