Center Channel Frequency Response

I have to go with one system for all -- don't have the luxury of one system for movies and another for music. I found this response in an old thread:
A center channel speaker that is expressly designed for HT will have a restricted and taylored frequency response which makes speech more easily intelegible. However, such a speaker is not good for multichannel music, where the center (and surrounds) should be the same as the left and right fronts.

First question: Is the underlying premise correct? Are HT soundtracks and multichannel music formats mixed differently with respect to the frequency range of the center channel?

Second question: If the answer to the first question is "yes," why would a more restricted frequency range on the center channel make dialog clearer? Seems to me a clear midrange is a clear midrange. Am I missing something?

Thanks,
Lou

Anecdotally, 60% of a motion picture soundtrack's energy ends up in the center channel. It gets more than its fair share of the musical score and effects.

You're going to have issues with any speaker in a placement it wasn't specifically designed for which can be worked around with equalization (shelving filters) that may take the form of room correction (Audyssey, DEQX, Lexicon's product, Tact, etc.) that's configured automatically using a calibrated microphone.
