I have owned two pairs of KG4s.
I think the earlier ones sounded better for some reason.I suspect the tweeter or crossover was changed on later ones.The earlier pair was prone to burning out tweeter voice coils-but that was a simple replacement job.
They can sound really nice with very tubey sounding amps like a 300b SET.
Also you need to stand mount them so the tweeters are at ear height when sitting down-which goes for any spoeaker.The little skirt on the bottom is best removed.
