My Spendor SP-100 speakers are 14 years old but they are my "new" speakers. The drivers and horns in my high-efficiency speakers date back to the 1960s and 1970s.
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.
