Spade jumpers for 803d3

I have some 803D3’s and had been previously using a biwire cable.

I found a good deal on a much more length appropriate set with bananas on both ends. However I just realized that the jumpers that came with my speakers are bananas as well, so I need to purchase spade jumpers.

here’s my stupid question: do I need to get a certain size spade? Or is the diameter the same for all speakers? I can’t seem to find anywhere in the manual that lists the size of my speaker posts.

also any recommendations for reasonably priced jumpers? The speaker cables are analysis plus big silver ovals.
