Question: Resistance Readings on Older K-77 Tweeters

Digging through a stash I discovered of Klipsch K-77 Tweeters  (of exactly 3 - 2 have square driver 'M's, 1 round Alinco I think ). I'm getting measured values of respectively: 5.9, 6.0 and 6.6. I've read Bob Crites' mention that a reading of ~6.0 Ohms is a good thing. Bob says nothing about what degree of accuracy to expect.

 

The round K-77 must of come from my old Cornwall's, the square K-77-M's are the original pair from my 1982 Belles which were replaced with CT-125 tweeters I purchased from Bob C..

 

If I decide to sell these can I safely assume the above values are close enough to 6.0 and that resistance values in this range reflect good testing diaphragms only?
