Unknown & Interesting to watch ...

A USSR speaker being restored.
Fascinating drivers & crossover > I think the cap's are even oil-filled.
Interesting to watch.

Why would you cover the tweeter with a 'cheesy' metal grill ???

 

[Kev06]

To protect it from physical damage. Possibly even by bears; I quite like the mentality of engineering in that area of the world - I believe it would now be called Latvia, though stand to be corrected.

Did he check if they were any good? Did I miss it in the vid?

 

[kaameelis]

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!

All of them sound awful

I was hoping that other people would also post 'strange & interesting' oddities.
YouTube's (without advertising)
CHEERS

Not strange, just some speakers from the '80s
The restauration part, I really don't mind.
Who asks for metal grilles, will be rewarded
Also some good Police in this

These had a Visaton midrange, with cone plastic cup on the back

Active speakers from USSR.
Drivers are same as in S-90 only woofer has feedback sensor installed.

 

[kaameelis]

Feedback sensor is from piezo headshell.

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.

 

[Mister Audio]

More of 'Motional Feedback'.

 

[Mister Audio]

And there's MORE ...

Somehow, these video's are conjuring-up that unique smell of soldering old European circuit boards.

Although sticker on the back may say RCF, the drivers are RFT

Some CORAL speakers >
