I was looking at the owners manuals for the new ICON line specifically the XF-48 and subwoofers in that line, and noticed Klipsch just specifies a 5 year warranty. Did they include the amp in the 5 year warranty on these models, or was it just omitted in the owners manual? In the past any amp/electronics only carried a 2 year warranty. Is it also 2 years on the ICON line? I am looking at these for another room, and am curious what the actual amp warranty is?
