The information, of course, would be there on the original prints-- it would just be a matter of what frequency range the speakers in any given theater were able to generate.

Particularly with low-range, though, you have to be careful not to fry your subwoofer. A friend of mine ran the Sensurround disc of EARTHQUAKE on his set up, and after about 10 minutes on his 150 W subwoofer, it started to fry!
