Spade to banana connectors, do they exist???

Y'day I went to connect an SVS sub to the 2 channel system. Being a good lil' audiophile I chose to utilize the subs crossover and connect it via its hi-level in/outputs. Then I discover the SVS has these cheapo receiver type binding posts that only accept bare wire or bananas instead of a quality 5 way post that will easily accept a spade. All of my speaker cables are terminated with spade ends.

Do banana termination adapters exist that allow one to attach them to their spade ends? Years ago I found a set that allowed one to attach their spade ends to the base, tighten the spade to it, and then plug in the banana termination. I don't desire to buy new cables, or place new ends on my cables, or resort to zip cord. Thx 4 the assist.
