A very very long time as long as you don't cook the coil or drive it into suspension failure. Within the limits the driver, subwoofers will last a LONG time. 99.99% of the time it's abuse that kills. It's very rare for subwoofers to fail because of a spider giving way (surround glue issue is another story - it depends on the build house and materials used).
