I asked this same question, only about all of the speakers, not just the QS8s.... The bulk of the people responded "bare wire" unless you do a lot of speaker swapping, then they said any good quality connector would work, and they make disconnecting and reconnecting a breeze... For me, my Axioms will be it. No swapping out for something else, and then swapping back, so I am going to just use bare wire, but maybe with a bit of solder (tinning) on the ends to keep them together.
