If you listen critically to classical multichannel (DVDA or SACD) you need five (count em) identical speakers.
If you watch movies the center speaker should be optimized for dialog, which means far-from-flat frequency response.
Most of the stereo signal on stereo recordings is common mode (Mono). Although it is rarely done, the center speaker in a derived multichannel system should logically be superior (not inferior) to the others.
