Grundig speakers.

Grundig made some cool stuff in audio & radio -- including a number of speaker systems with electrostatic tweeters. Do the above-pictured loudspeakers happen to have ES tweeters?
Speaking of which
it is kind of amusing, in retrospect, how common electrostatic tweeters (typically simple, single-ended designs) were for a while in the 1950s. Philco (of all companies) made some pretty prosaic radios with ES tweeters, and standalone ES tweeters, back in the day, e.g. *
(random borrowed image from teh webz)
... and, of course, Radio Shack famously sold add-on ES "supertweeters" for the famously treble-compromised
Acoustic Research (and other) speakers of the late '50s/early '60s. *

Early on I think the R/S ES tweeters were JansZen OEM, but later I think
they were Japanese-made knockoffs (or maybe licensed versions, who knows?).
I -- ahem -- have a couple of pairs of the R/S add-on tweeters Their simple electrostatic power supplies need to be rebuilt, though, before I'd have any confidence in plugging any of them in, much less actually trying them!

Unfortunately the seller removed the original "oval" speakers and built a shelf inside the cabinet so a bookshelf speaker could be placed. It is even suggested that Klipsch KG4 will fit (oh, the horror!).
I remember being at some kind of sales training (maybe Martin Logan?) and the trainer stated that the very first speaker used with a telephone was an electrostatic type. He said the electrostatic speaker predated the moving coil or dynamic type speaker. I don't know how true this is. -
After a little Googling the model name is "Raumklang" which translates to "surround sound", pretty cool eh?

My belief/understanding is that the carbon granule 'microphone' was used in the earliest phones -- but I dunno.
Sad about those Grundigs.

I bet if you looked up "Gruv-Glide, Las Vegas" you'd get some interesting results.

... and that's why, when looking for information on either transformers or transmissions, it's best to type out the whole word, rather than using the slang term that is often applied to both.
(at least unless "Safe Search" is turned on -- and maybe even then)

Ah, yes! The Klipsch ear bud. Just insert into the ear canal until you feel the miniature icepick scraping the surface of your eardrum.

This thing looks like something you would expect to see on the old TV series from the '60s, "Lost In Space".SeleniumFalcon wrote: »

Beat me to it. I was going to say that they probably sound congested. -
Great minds....
