Bi-wiring is a pretty funny phenomenon in the audiophile world. I've read quite a few statements by those that use bi-wires regarding their intention of by-passing the speakers' internal cross-overs. Others claim to be isolating the high and low frequency signals from each other in transmission.
If you do a bit of research into VERY basic electrical circuit theory, you'll realize quickly that there is no real difference between bi-wiring and using standard cables. A basic node-voltage analysis will demonstrate that, so long as both ends of the wire on the amp side are attached to the same terminal, the signal at the speaker ends will be identical. In this way, the speaker is receiving the same signal at the dual terminals whether they are connected by a little plate or a common connection on the amp side.
The only real possible difference would be in resistive loads when comparing wire straight to both sets of terminals in the speaker versus a single wire to one terminal and a connecting plate to the other terminal. Of course, the difference is so minute compared to the load of the hardware as to make it ridiculously trivial.
If you wish to use the speakers, simply attach both pairs of connectors to the same terminals on the back of your M3's.
