They made a lot of GREAT speakers before Bose came on the scene. I have found some GREAT sound gear at Goodwill and thrift stores, for practically nothing.
My father was an early stereo enthusiast, he had custom built speakers that once knocked a clock off our living room wall, Mom was not happy about that. He used to take me to stereo shops, we weren't rich, mostly looking. I remember looking at one of the first electrostatic speakers, they buzzed with high voltage, don't put your hands near the open electronics in back lol!
