Tightening binding posts problem


I am having a hard time getting the binding posts tight on me speakers, I have paradigm studio 100s. By hand, I can't get them real tight. My cable is terminated with WBT spades. Any suggestions?

I suggest some Kung Fu practice;then try again.Upgrading posts or/and using bare wire connections can be rewarding as well.The idea of using tools in this case just repels me.
X-terminators add an interface level and, while convenient, slightly veil the sound.
The AQ binding post tool is the goods - highly recommended.
If you cannot tighten them even with a socket or the AQ tool, something may be broken as Ncarv points out, or you may have to get inside the speaker to tighten the nut on the crossover side of the post - had to do that on my DSigs when I first got them.
Thanks for all the responces, it used a socket very gingerly and that did the trick.
