To identify the driver you’ll have to find a 6 (usually) digit number on the frame or perhaps the back of the cone. There isn’t likely to be a label on the magnet, in a commercial speaker.
LOL I just removed the sliver of a connection plate and identified that the speaker box is heavily damped with the old yellow packing. That's all I could see. And I thought I had a good plan. 🤓
I guess its a rabbit hole session of looking at pics trying to compare surround profile and whizzer diameter / angle.
A god thing for me at least is the possibility of a highish Qts driver if the sealed box implies such.
Actual question for yous guys. Is the bulged profile of the tweeter common to many classic manufacturers or just a few and if the latter which few?
Thanks

Glad you mentioned the bulge. I thought my eyes were fooling me.
The speakers look to be from the late 60’s maybe early 70’s but those tweeters are from the 40’s or 50’s. If I am correct, they are a 3” closed back, square framed, alnico magnet without a field cage. Very common. Not sure about the bulge. It does look a bit odd for sure.
