Actually there is just one center speaker in a movie theater. The left and right stage speakers do not routinely reproduce dialog, but rather just sound effects and music. If there is a problem with that speaker not producing enough outut for a particular auditorium, the solution is simply to specifiy a larger speaker rather than using multiple speakers reproducing the same signal.

For the home though, two speakers producing a phantom image is just fine - like I posted above, all stereo (and multi-channel as well) recordings have information panned equally to both speakers and all points in-between. In a home, dialog intelligibility is not nearly as great a problem as in a large movie theater.
