Why do my KEF C-80's have three posts in back?

I just bought a pair of mint KEF C-80's off Ebay. They have three posts in back for speaker cable: red/black/red.

Why is there a third post?

How should I wire these for the best sound: the first (from left) red and black post? Or should I use the third post?

The C-80 is designed for two types of room positioning, not any form of poncy biwiring.

Either

1. Against a wall where the right hand pair are used.

Or

2. Use the left hand pair in a "normal" position where the boxes are >18" away from room boundaries, so the bass unit isn't rolled off so quickly.

Now, I think if you look closely at the red binding posts you'll see some small symbols like ▀----▀ & ▀ ▀ the one with the horizontal bar indicates wall placement.

Don't connect the red terminals together as something is likely to be damaged
