So assuming one does not bi-wire and leaves the jumpers, it really does not matter which posts you use as long as you do not do something silly like connect your leads to both positive or negative posts. But then again if you are one to use expensive speaker cables and say hook the cable up to the HF side - you are now depending on the jumpers to transfer the signal to the LF side and to me the stock jumpers look like zip wire terminated with spades, so potentially undoing your expensive speaker cable ?
Thanks again
