Who has the oldest speakers?

Bought new, Fisher XP-7's in 1964. Had them in layaway for 3 months till I paid them off. Still sound good with flat bass...presently parked in the effects field of my HT setup.

1950's 10 inch Jensen in a same era Danelectro blond tolex 6V6s powered guitar amp with vibrato. Friend gave it to me free for repairing his midi pedal board and for me being his guitar tech and the stage manager at his 1998 Wamboozy Long Island Music Festival (350 miles from LI) at Snow Ridge Ski Resort in Turin, NY.
1975 Acoustic Research AR-11 with AR replacement woofers, tweeters and foam grills. Waiting for intergrated amp for this bedroom system. Served me well with a 1974 Pioneer SX-1250 receiver until I came across this site 2 years ago. You know the rest... upgrade!

My parents still have their AR-1's. I am not sure how old they are (the speakers, I mean, not my parents.)

I have a pair of AR-11s that sound really good despite the fact that the foam in the drivers is deteriorating. Anyone know if replacement drivers comperable to the originals?

Thanks

I have a pair of Wharfedale W45's - vintage 1971 - I'm the original owner - my first speakers (they sounded horrible, but great cabinets, so I rebuilt them with better drivers, crossover 3 years ago). I also still have my second pair of Speakers - 1976 Infinity Monitor IIA's. I hade the woofers refoamed 2 years ago - they are mint, original, and sound great.
