I just had my sub sent in a little over a month ago. I bought my at Best Buy (black friday or whatever they call it) and I took it back there. After jacking me around at the service counter telling me I had to send it into Klipsch and I argued that Klipsch told me to send it in through best buy they sent me over to the Geek Squad counter. Once at the Geek Squad counter they tried to tell me that I would have to pay some high dollar shipping and other repair fees until I told them I thought it was still under warranty. They looked the warranty up and said that it was good for 5 years. My speaker was under 2 years old by a couple of days but I have it on a document from the Best Buy Geek Squad that it is covered under warranty for 5 years. Anyhow I have the speaker back now (no charge) and it is working like it should again. I would call Klipsch if I were you and see if that place that you bought it from is an authorized dealer. Klipsch should get involved if they are and should help you out with it. Bottom line is according to my document from Geek Squad, that I have stowed away for future reference, the speaker warranty is for 5 years. That's a hell of a warranty, to bad you're going to need it from what it looks like[].
