There was some interest in vintage audio equipment in one of the other threads, so I thought I would start this one.
My dad is an antiques dealer, he let me go through one of his storage areas to see if there was anything I was interested in.
I found these Bose 601 Series III speakers from 1986. They are in rough condition, pretty crusty and neglected. They need to be refoamed, need new fabric, and the cabinets are in poor shape. One of the goofy square speaker covers is broken too.
In good condition, people are paying between $600 and $1000 for a pair on eBay.
I also found the original unopened paperwork.
