Newb question about testing old speakers

Leave them alone. Duntech was a reputable company founded and run by John Dunleavy in Australia during the late 70's/80's. He made very good speakers! Don't go messing around with the crossovers. The idea that just because they are old the parts must be changed is stupidity!

Unless you have three listening rooms why keep all three pairs? Unfortunately it might be difficult to sell a pair or two. What amps do you have to use with them?

Thanks jasonbourne71. I am not trying to "tweak" them, just ensure they're all equivalent basically. I figure there's a high probability that one of their caps is worse than the other.. If anything, I would just replace with a newer cap.

But I'm going to use these as atmos/surround speakers.
