2 and 3 look like Jensen.

Yeah, I suppose since it says it on there, it makes sense that is what it is. That should have been my 1st clue. :sigh:
I know sometimes guys like to ID stuff for the challenge, but I guess that woofer wasn't. I was too busy researching other stuff. :nono:
I see the L is for 8ohm.

Would the woofer reading 5.9 ohm mean it is whiffed? :scratch2:
I'm still unsure of what the "L" means at the end.

The green one looks like the same type of 12" Jensen that was in many Fisher consoles in the early 60s.
The closed back speaker looks like some of the Danish speakers that Fisher also used for mids.
The first speaker looks like a CTS or similar that was often used in the old Magnavox consoles, like the '58 that I have.
...just guesses, but maybe puts you on the right path.
All decent, if not actually good speakers potentially. It just depends on your application.
It is interesting to note you impedance measurement of 5.9 and follow on question, which is similar to my observations and questions here:

Perhaps some of these older larger 8 Ohm speakers just test much lower impedance statically? I know for a fact that a similar Jensen as yours was used as 3 way speaker setup with the Fishers, where three 8 Ohm speakers were wired parallel for a 2.5 Ohm expected load. So again, maybe 5.x Ohm isn't unusual for these older speakers for 8 Ohm impedance.

No, that's a pretty typical DC meter reading for an 8 ohm nominal driver.
The reason is this... You are measuring DC Resistance with your meter. Impedance is AC resistance and differs from DC resistance in that impedance changes with frequency. Speakers have an impedence curved dependent upon the frequency range being played through them. When they say an 8-ohm speaker, they mean the average is around 8-ohm. The DC resistance you measure for what's generally called an 8-ohm nomimal speaker is typically below 8 ohms, in the 5.x range is not uncommon.

Ahhh, that makes sense...just like a speaker having a nominal impedance for the driver set.

I love any info I can get...thanks for sharing!
