Long story short, I had one of my Klipsch surround sound speakers go out recently. I called Klipsch, and they were very professional and courteous. Instructed me to dig out my reciept, which for some reason I could not find. I did find my installation receipt however, and I know I had purchased them in June 2008. I called Klipsch back, thinking I had no recourse due to failiure of not finding the receipt. They had me take a pic of my serial #, and email it to them. Hour later or so, I get an email back informing me they were sending out a new speaker at no cost. What a great company. Highly recommended their speaker's before this happened, but this was the icing on the cake for me. My business is pretty much theirs every 10 years when I buy new equipment....just thought I'd share. Thanks Klipsch!
