If I were going to use jumpers, I would connect the speaker wire to the top tweeter terminal, and run the jumper to the bottom bass terminal. Use some high quality speaker wire, not the brass ones they come with. Manufactured jumpers are also available from AudioAdvisor, Mapleshades, and others.
But actually I would Biwire them and not use jumpers, which is what I think you are referring to in your last sentence.
