I listen to music pretty loud sometimes. I play movies with significant amounts of music in them sometimes.Mostly agreed on the idea that a good speaker for music should make a good speaker for movies too. The only exception would be those that are unable to handle lots of power and play loud enough. Now, sometimes the reverse is not true - sometimes a speaker will be voiced to be initially very impressive for theater but end up disappointing for music. Ultimately it will probably prove to be not as great for movies as initially thought for the discerning listener though.
The true bottom-end of sound, where the subharmonics of, say, Master and Commander run, are perhaps not heavily represented in music (they do exist though). I would also say that the possibility exists in stereo LF recordings of having sounds that will not sum well electrically to go into a subwoofer; but I think these are relative outliers rather than common-case.
