We find this DDR KSP 130 K based speakers in one of our project building. Those speakers (12 pair) are installed by a communist party, into some cinema room, to check the incoming movies for the young communists.
You can see this piece of history and the interesting design.

Off course cannot be stay like original :) We hacked with some ESI active amplifier, what we find in the garbage!

At the end, we are surprised. It's sounds so good and enjoyable!

Still need some modification and more testing, audio measurements.
