How long do the speakers last before a service?


I know I will get various answer, but are there any simple rule? I am aiming for the used speakers. Say if I get a 5 years old speakers. How long will it last with me (presumeable the previous owner take care of them well) before it needs a service/repaired/calibration?

I would feel awful if I can use a used 1k speakers for only a year or two and then need to pay for the service again.

Any rule of thumb on this?

Is there any reason to turn the cones 180 degrees every five years or so? Would this help prevent the rubber surrounds to hold there shape longer?

With the exception of foam surrounds, most speakers are pretty indestructible--unless you do something to destroy them. I've got some 20-year-old rubber sourrounds that are still in good shape.
