@Da Wiz is correct, everything about a speaker degrades over time. It's akin to a car in that respect, the best it will ever be is when you drive it home for the first time. Items wear and deteriorate over time, it's the nature of the beast. And just like a car you can replace failed or underperforming components provided the parts are still available. Unless something is a classic - or has sentimental value - it may not be worth the expense though.
