Magneplanar speaker terminals. is there an adapter to....

I was looking at a photo of the back of Magneplanar .7 speakers.  They still use those dumb speaker terminals that will not accept a higher end banana plug, (possibly a twisted up spade lug)... Therefore, does anyone know if there is an adapter that works with their terminals and allows larger banana plugs to be used, or  simple spade lugs.  The company  makes great speakers, but is living in the Stone Age when it comes speaker terminals.   Thank you .
