Who has the oldest speakers?

When my older brother came home from the service in 1971, he had a very large Pioneer stereo system. It came with some very large floorstanding speakers. I don't see him very often, but I saw him last month and to my surprise, he still has the same system, with the same speakers and believe it or not, it sounds great. He takes really good care of the system and it is in immaculate shape. That makes those speaker about 30 years old, more or less.

How about you guys?
