A good pair of speakers can last a lifetime, provided they are kept in an environmentally controlled environment. Not anything special, just a comfortable temperature and humidity. Paper cones can't be in really dry environments, but obviously, they can't be exposed to moisture either. Cloth surrounds are very durable but foam surrounds are weakened by sunlight.
