IF one thinks a particular speaker from teh 70's is the best for them then that is what they should buy.
I still have my OHM Ls from 1978. I had to refurb them with some new parts but they can be had newly refurbed from the maker still for about $500 (they cost $400 back then)and would float the boat of many a buyer these days still.
The thing that many box speakers from back then did not do as well as today is soundstage and imaging. If you don't care about that too much, put some old speakers on a good modern amp and most people will be good to go.
