This speakers are from Latvia and it was Latvia also when speakers where produced.
No need to check, in former USSR there are tens of thousands S90 speakers.
From assembly lines where coming in maximum 500 pc. per day in the month ends and even more in quarter ends.

Interesting indeed! Pictured below, the Radiotehnika S-90B.
From 1980. Very industrial looking!

The older RCF drivers that made it across East German lines in the 80s weren't half bad. I used to buy a version of their 6.5" from Conrad Electronics in Munich when I was a teen. They worked well in a 30 ltr vented box with a larger tweeter and had decent xmax.

Although sticker on the back may say RCF, the drivers are RFT
Here is some old RCF info. >The older RCF drivers that made it across East German lines in the 80s weren't half bad. I used to buy a version of their 6.5" from Conrad Electronics in Munich when I was a teen. They worked well in a 30 ltr vented box with a larger tweeter and had decent xmax.
