Those were speaker cables with RCA connectors, not coax cable. At least I have not seen one that was.
Back in '74, it was common for Japanese all in one systems (bottom end, but better than plain radios) to use RCA connectors for the speakers. The cable was hardwired into the speaker, it was not coax, more like 16 gauge black zip cord and terminated in black RCA jacks.
I had a Panasonic setup like that.... the main unit had the receiver and turntable and it came with two two-way speakers.
Read this.... fun.... memories.....

Someone mentioned 24 ga wire and I think those are the ones I remember. Yes, many were hardwired as you mention. I remember they often had a twist tie stapled to the rear of the box to contain the wire when in transport.
^ The Radio Shack catalog was an incredible read then. It was huge.... i used to subscribe to Stereo Review, High Fidelity and Audio magazines. I had stacks of all the Japanese audio brochures from '73 to '76.... That's when I moved up to a Marantz 2220B..... wooo! You impressed? ;-)
Yes Tony, always impressed. Back then, the amps I owned said Realistic on the front.
I don’t remember the specific plugs that Galu is mentioning but it certainly makes sense to have the plug do the auto switching.

Cal.... Realistic... you are a young one... 🙂
That's Doc Severinsen, huh? Straight Outta 1974.
I recall I had some plaid polyester pants at that time...
Cool, man... cool... from the days BEFORE disco! Doc's daughter looks like she belongs in The Partridge Family.
BTW, I had the Pro4AA myself. Still, that looks like a very interesting headphone splitter.

In some systems a bipolar cable terminated with RCA plug can be used in different ways and they are available on the market nowadays.

The one that had a spade and a pin was popular in some parts.
You two reminded me a nice memory: Stereorama 2000 Deluxe by Reader's Digest!
You ordered the system by mail and paid in small monthly installments.
I paid all the installments, but some friends only paid the first one and then that was it.
There were no consequences of any kind, and then the word spread (without the Internet!) and no one paid him anymore.
After a couple of years the offer no longer appeared in the magazine.
The Internet is wonderful!

Mine was the McGee catalog. I used to take it into the can with me, as someone would a Playboy mag. Never had *that*urge, with all the woofer porn, but plenty of drooling and dreaming.Yes, good memories for sure. My favourite magazine back then was the Radio Shack catalogue.
