My Infinity RS 1.5s were built around 1980. My backup speakers - Infinity Qb's were built around 1978. I've had lots of newer speakers, but I like the vintage Infinity sound, so I picked these up over the last few 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.
