Help me identify these elac speakers


I found these speakers at an auction but they have the wrong model number. Anyone here know what they are. Also, what is that speaker protection thing?

You are welcome:

 

My main/favorite speakers are vintage Elac S-517 drivers powered by 3 watt amps.

Have you heard the speakers? Are they difficult to drive and are they worth it for around $200?

No, I've never heard them except for an online video (Youtube?).

I don't recall them ever being available in North America, but maybe I missed them.
