You can fuse speakers but its ability to provide useful protection is limited. For one thing, the the time/thermal properties of the fuse are different than that of the speaker. And for another thing, the current ratings available aren't usually what you need. So both of these problems make it hard to get the right size. One standard size will be too small and the next standard size up is too large. That makes fuses generally inconvenient to use for speakers.
