So my grandparents had a pair of 1967 Model h700s, which are now in my hands. I wanted to hear how they sounded before I determined wether or not I would sell them, so I put my speaker knowledge to the test and looked for a 3.5mm port, but I couldn't find one, so I gave up.
Questions:
1. What equipment would it take to connect these to something from this century? (I have no experience with speakers, amps, anything.)
2. Assuming they work, how much do these things go for?
Any information would be much appreciated, thanks.
I'm sorry if this is in the wrong place or anything.
