I think what he is saying John is to leave the speakers on the TV stand, but create a wide bracket behind them to simulate them being close to a wall.

I'm sure you might notice some improvement, but the wall is a lot larger overall and has more reinforcement. I don't know how thick, or what material your thinking about, but not sure it would have the same gains as an actual wall.
