I'm considering purchasing some Klipsch kg-4 speakers from craiglist and was wondering how I might be sure they are authentic. The picture looks like the old light finish from the eighties rather than the black finish here on klipsch.com. Also, I'm concerned because of their age that they may have been repaired in the past, possibly with substandard parts. What is a reasonable amount to pay for these speakers in the current market? Can the community recommend any tests or tricks to make sure they are legit and in good shape?
