For HT most people set them to Small. For heavy music use there is more of a mix, with some people setting them to Large and taking the sub crossover down much lower or in a few cases turning the sub off completely.

The problem is pretty simple -- in the music world the M60s are "full range" with the exception of the lowest organ and synth notes, while in the HT world 35 hz is just the beginning...
