I would have begun my first reply with "I know you're kidding, but...", except I wasn't sure you were kidding in most of your post. I could tell that, like me, you think that bi-wiring is BS at "So when I stuff two wires...", but a lot of people really don't have a clue "how the amp knows". Forgive me for not recognizing that you did know since you asked the question, and it did have an answer.
You next asked a question (how to get a complete transition between 749 and 750 Hz) that at least theoretically has an answer, even if not a realistic physical one, and I gave a theoretical answer. If that was an attempt at reductio ad absurbum, it don't work.
And, thanks, sivadselim. Yes, I did mean that reply to the obviously facetious question in jest - hence the comment about magic, and rare, for me, smileyfaceicon. At least you got it. Mostly.
The fact is, in bi-wired systems the wires do carry different frequency bands, so sarcasm that questions that is, IMO, misplaced and adds nothing to the discussion, only fuel to the fire. Whether splitting the bands between wires actually makes a difference or not is completely different.
Sorry for misunderstanding your post, but I'm not alone.
