Klipsch KG4's bought new in 85. You will have to pry them out my cold dead hands; they have been rarely hammered plenty party's - many cops, and have performed faultlessly all these years.
How old are your speakers
I am wondering how many listen to old speakers. I am not looking so much as to how long you owned them but how old are they. Are they your primary speakers? I am listening to a pair of 2003 Verity Parsifal Encores and continue to be pretty pleased with them.
