the dual posts on the speakers are for bi-amping, and as rdgrimes says has to be done in a way that actually makes a difference or else it too may end up being just as fruitless as bi-wiring is.

I don't mind appearing to contradict my betters, so Passive bi-amping
can make a difference when amplifiers of different characteristics are utilized. A typical example would be using a solid state amp for the LF and a tube amp for the HF. There will be a difference, both clearly audible and measurable.
I am not saying it will be better or worse, but it will be clearly different, and some folks are passionate about this type of passive bi-amping and like it a lot. It takes some work to do it "right" whatever that may mean, but I would not classify it as fruitless or characterize it as not doing anything. I don't do it, so I'm not advocating for it or against it. It's just that if we're telling the bi-amp Gospel here, let's read all the verses.
Having written that, the idea of passively bi-amping from a receiver is of little merit other than to have two wires going to your speaker, which can have a visual impact on people, including your friends. "Wow! Look at that: two wires!"
I'm not above spending a few bucks on some (used) high end, thick cable that's conductively no better than 14 Ga. lamp cord but looks bitchin' when connected to speakers that everyone will see. Everyone automatically thinks, "Man, those must be really good speakers. Look at the size of those cables!" People who expect good sound usually hear it.
Everything I bi-, tri- or quad-amp is run through active crossovers before amplification, so it is (by my taste) bitchin' already, but spending $20 or so on ebay to get some fatty cables is icing on the cake. OTOH, on a four-way, quad-amp setup, I'm actually running four pairs of 16 Ga. (yes, 16) plain wire per loudspeaker to the individually EQed drivers, since no one can see any of it. It works just as well as the 10 Ga. stuff with super fat insulation on the actively bi-amped speakers on the main floor that everyone can see.
If I had extra cable lying about, like the 200 ft. spool of leftover 16 Ga. I've got, and a spare amp, I would passively bi-amp or even bi-wire something just because I could. It won't hurt any more than it likely won't help. Then I'd pray that Smarty-pants, Bill and rd would stop over so I could see and hear their reactions.
But I wouldn't go out and buy wire just to do it, since I know that it's going to be money spent for naught, plus they're probably not coming over anyway.
Also, don't forget that adding more wires statistically increases the chances of mucking something up, miswiring, shorting something out, etc. So be careful if you do it, and remember that this is about enjoyment. If you want to try it and it gives you satisfaction in the attempt, then who can say it was wrong? Just do not expect a miracle, not even a minor one.
