Not likely unless you stored it in a real damp place or in direct sunlight, there should be no issues. Trust me, Debbie at Axiom will take good care of you and present you with options that will be hard to turn down. Depending on the age of your subwoofer, they may be able to swap out the parts or, so I hear, they will have an EP-175 showing up in early July in their refurb store!

Speaking of refurb, they have a black EP500 for sale now...
