Harsh?
It might be meh now, but was that so when it was built?
My first thought was the thing was massively top heavy and I wouldn't want to be near it when it toppled. Second was that I was sure I'd seen captain Kirk trying to outwit it on Star Trek...
?? ''A prototype speaker made for the world's fair''? For the world's fair? They look kind of frightening. So freaky and weird. I believe it is a psychological trick🙂. RCA... Apparently some people on Earth have reached a heightening - hear images and see sounds...
It's special because of the historical significance. 'Not because you might view it as a crude design by today's standards.

Yeah, it looks like what I imagine are the speakers for public address in the novel The Big Brother. Scary!!
I don't think its meant to hang, rather to be built into the ceiling. That creates baffle for low frequencies. Otherwise they would hide the crossover. It will look like wasp nest after installation.

I'm not sure if that's not more alarming than having it stood on the floor. How much does it weigh? If I was in a building and saw it protruding from the ceiling it's something I'd walk around not under.
My imagination, backed by checking forums and see pictures of omnidirectional speakers, suggests that the cone part at the edge is an omnidirectional speaker. The tapped edge does not confirm that, thou...
A (auto?) transformer and a coil is what I see

Ah yes, I think you're right. The metal disk is the plane of the ceiling. The woofer at top functions infinite baffle. On the floor maybe you'd flip it over and set the woofer into as big a box as your space can accommodate.
It's large, but you see big 'ol line arrays and various PA setups hung from the ceilings at sports venues or concerts all the time. Definitely a pro install thing tho, not something to trust to the handyman from the Home Depot parking lot.
they make 70v ceiling speakers with a transformer on em. So if you have a long cable run to it you can go higher voltage / lower current, and not lose so much power in the cable run (resistance heating ~ current). 2 transformers, identical (mounted to not interfere), one for the woofer one for array?

I wonder if there's one more of the smaller speakers pointed straight down.
Looks upside down to me. The woofer should be in a cabinet. Missing? Makes more sense that way too.

Somewhere between the Stewart Hagerman loudspeaker with the bowl shaped deflector for the PHILIPS tweeter or a glimpse of the Walsh driver idea perhaps? Who is to say that big driver was for the bass?
Is there any evidence it was at the World's Fair or even made for it? I don't see any.
Designed (assembled..) by committee, the second order crossover parts (the two inductor coils and capacitors) would interfere with mounting.
I doubt the prototype was ever installed anywhere, or that it ever made it into production.

Asking $1200 for some 1950/60s era TV speakers- well, they are antiques 😉
Not very large, the aluminum low frequency reflector cone and cluster of 3" high frequency drivers only extend 15" below the mounting disk.
The cluster looks like it may be made of some type of foam core, I'd estimate the total weight around 25 pounds, the coils about half that weight. In production, the coils probably would have used iron cores, and would be a fraction of the size, weight and cost.
Yes, there's a tweeter pointing every direction 🙂

I don't either, but I'm sure somebody wouldn't lie about the provenance. Not on Ebay...that could never happen. 🙂

I was confused by the size, thanks for bringing me to reality, as those are not high Q 12" woofers but tiny paper tweeters.
And there isn't a Celestion Axi2050 at the top of the 360° Smith horn but it's just a 15" frame holding a membrane.
Now... ceiling speakers
