The expected life of an inexpensive basic speaker on wheels could be anywhere between 4-6 years. Premium range speakers could last for more than 45 years, taking their material type and surroundings into consideration. Some of the components could die out after a few years, but if proper care is taken, they could last longer and add to the longevity of the speakers. The speakers and their expected life could also deteriorate when they face sudden power surges or loosened connectivity.
