Both Tributaries and IXOS make them (I've also seen some others but can't remember the brand).

90 degree angle banana plug?
Is there such a thing? I have my center channel speaker on a shelf above my television. With the conventional banana plug, it sits out too far from the wall. Looking for a 90 degree banana plug that I can use,so my speaker can sit on the shelf all the way. Thanks for the help.
