I spoke to a SVS rep today. He said the warranty is transferable. All you need is the serial number and original purchaser. He then went on to say that the important thing is the serial number and they will take care of it. Warranty is 3 years...you will have a warranty up to 3 years from the ORIGINAL PURCHASE DATE.
So...with that being said, if you see a good deal on one, grab it and experience great customer service if it needs serviced.
Hope this helps
