Vintage Klipsch question(s)

[2020]

First, my apologies if this is the wrong place for this question. Please advise if there is a better place to ask.
Now here is my question:

During the time of the AA crossover, can anyone tell me what impedance drivers were used?

At one time, I thought the woofer, mid driver, and tweeter were all 16 ohms. Then I heard the woofers were 4 ohm, the mids were 16 ohm, and tweeters were 8 ohm. Latest I heard was woofer 4, mid 8, tweeter 16.

Can anyone school me?

Greatly appreciated.

Might you identify the specific model and vintage (year) about which you are interested?

Good point! Sorry I didn't think to mention that. The crossovers were removed from Klipschorns, I don't know the specific year, but assume 1970's.

Woofer = 4 Ohms, loading to the horn raises it to the approximate 8

I don't know about the others in spite of owning them for decades.

Thanks, Coytee.
