Snell Type K loudspeaker ?

I picked up a pair of Snell Ks and have what is probably a stupid question. The speakers have two sets of binding posts making it possible to biwire. One of the speakers has a piece of heavy copper wire twisted like a pretzel through both sets of posts, while the other doesn't. Is this some type of homemade jumper? I have a picture but don't know how to post it here.
