As you go through the practicalities one can see how the horizontal D'appolito configuration provides the optimal solution to these problems. Anchoring the centre channel to the centre of the screen is very important to acheiving theatrical effect. The MTM configuration involves tradeoffs as well but set up properly it results in a well-balanced, wide dispersion of sound and increased off-axis response. The challenge is that the horizontal centre is in most cases still off plane with the mains. Hence even with the same drivers as the mains there will be a slight change in tonality and timbre.
