Speaker EIA Code CR 942 HR

[Hull Rust]

Hey, been scrolling through the codes and I can't find a solid ID in this. I'll post pictures, 1950s - 60s time frame.

Any help with an ID would be much appreciated, thanks.

There are no EIA codes there. Cone numbers are just that, cone numbers.

That said, those are likely Stromberg Carlson drivers.

Let's see a pic of the round one from the back, please.

Ah, thank you.

Nix the Stromberg.

I think they're Misco or Carbonneau

But, i am not certain.

They appear to be cadmium plated, that's probably a good indicator they're not Stromberg.

Edit: seeing the plastic voice coil cover makes me think they're mid - later 70's. The red cones are a bit unusual that late.

I expected to see a transformer mount on the round driver.

Do you have any back story on them?

I don’t know anything about them, came in as part of a trade. The one I opened has a tinsel flying loose, which is unfortunate.

Looking at the solder connections it isn’t pro work. With the binding posts I thought they might date further back. Maybe this is a home brew.

Agree with those observations, the terminals appear older than the drivers, and the whole shebang appears a DIY, dare i say "hack".

I'd agree
