They're called "Amfiton 35ac-018." They are old Soviet speakers, supposedly high quality ones. They are huge. I would like to hook them up to my PC, but I don't know how. I have a converter wire (red/black to one connector), but it didn't work. It had contact, but it didn't really fit to plug them in into the two available slots. Yet they did have contact with the connectors. There was no sound.
For pictures, schemes, etc., you can just Google the title. For reference, this is how they look: http://media.okidoker.com/data02/c/1/2/2/22519/63825/156978_2.jpg?updated=1245174196
