Does anybody know if I am able to bi-wire with the Harman/Kardon 247?

as far as i'm aware, bi-wiring doesn't have anything to do with the receiver/amp. check out this link for more info: http://www.polkaudio.com/education/showanswer.php?question_num=53

bi-wire separately sends identical signals to both the low and high frequency drivers on your speaker, which apparently provides much greater clarity. the only thing that can prevent you from bi-wiring are the binding posts on the speaker, not the receiver. if you have 2 pairs of binding posts on each speaker then you should be able to bi-wire them just fine, but remember to remove the jumpers. also do a search on this forum for bi-wire, it is sure to turn up alot of helpful results. i did alot of my research here before i made my purchases a few weeks ago :D

Bi wire or biamp?

But the problem is, if I get two wires running from each of my speakers to my amp, how do I connect them?

If your receiver has multi-room out and front left and right pre-outs, I can give you instructions to passively bi-amp your system.

to bi-wire you run both left negative terminals from the speaker into the one negative terminal for the front left channel on your receiver (same for left positive, right negative, right positive). it may be hard to do with fat wires, but you can find bi-wire cables for not huge $$. i got a pair on the bay for $52 shipped - 4 bananas on one end, 2 on the other. getting these kind of cables makes it really easy, but it can be done with regular speaker wire too.

don't bother, buy an amp and leave it at that. None of this what was the term used, Ghetto bi-amping ?!

Well, I know that my amp will allow for one bananna plug on each terminal, and also allow for a bare wire to enter on each side. Would it work to run one length out of the bananna cable part, and then the other thorugh the bare wire? Is it even worth it on my system?

If you mean the A/B speaker outputs, you are not bi-amping, you are bi-wiring. The outputs are usually tied together inside the amp/reciever, so it's no different than connecting two sets of wire to one set of binding posts.

I hate to say it, but you're incorrect. The term is passive bi-amp or the new nomenclature term ghetto bi-amp:cool: . You're sending two amplified signals to your speakers but, from one shared amp. I've done it with my HK receiver, but it elevated the THD way too high. The best way and I'm sure most will agree is to use two separate amps.
