Setting aside overload - mechanical or electrical - most speakers can be expected to last decades. The main thing that affects a speaker that is very old is the paper cone can get brittle. But I rarely see that on a speaker that is indoors in a controlled environment with pleasant temperature and average humidity. I usually see that in speakers that have been stored in hot, dry places like garages and storage units. The environment can also be hard on speakers in cars for the same reason.
