So I was cleaning out some storage and came across what looks like a large
1920s radio horn speaker driver, which I must have picked up someplace years
ago. It's about three inches in diameter, with a nine-foot cord, and it's
quite heavy for its size. (The driver itself tests very good.) On the top
it is embossed "Atwater Kent, Phila" and Type 5V. After doing some digging,
I found an old ad for it on that great AK website. The ad lists it as a
"Phonograph Attachment," but says nothing about what exactly that is, what
it does, and how exactly one would use it. I recall seeing some old ads
where something of this nature is sitting on a motorboard next to a
reproducer, but that tells me nothing. Does any out there know about these
things? Anyone own one, or is anyone looking for one? I'll be happy to
send you pictures if it'll help clear this up. Thanks in advance.
