You can buy bi-wire speaker cable - one termination on the amp end, 2 on the speaker end. Kimber 8TC is a popular choice, but pretty much every cable can come that way.
Not sure you'll see much of a difference over one wire and good jumpers anyway. Seems to vary with different speakers.
Or, yes you can can use bananas and spades with 2 runs, just make sure the cables are the same.
