What is this speaker cable connection?



I was given these speaker cable and told these were really expensive. But when look at the connection, it doesn't make any sense to me. I have used banana plugs before. But I have no idea how to connect these with my amplifier. Any help would be greatly appreciated.

What is your amplifier?
Both of those amps have binding posts that will accept bananas, pins, bare wire and spade lugs like you have. Just unscrew the plastic red or black knob and insert the lug into the area that is exposed when unscrewing the post. Then tighten it back up, as tight as you can get with your fingers or gently give it a nudge with a pair of pliers. You do not want them to move back & forth. Make sure the + & - wires are not touching each other.
