$100. I believe I got them for less. They also came with an equalizer and a stereo receiver. Their equalizer technology was one of their key selling points back then. I can only imagine Bose copied this idea when it made its speakers, except with Bose you don't get much control over the EQ and without it the speakers do not sound great. Fisher speakers sound great without the fancy EQ.

edit: And for anyone who doesn't know what old high end supermarket speakers sound like from the early 80s: I have $400 headphones that are less enjoyable to listen to.
