Re: Why Bi-wire?

Posted by Steve Eddy on August 11, 2003 at 11:10:41:
So I wonder two things: 1. Why does bi-wiring work? I’ve read several explanations, the most plausible of which (to me) is that it lets less of the woofer’s back-EMF into the tweeter.
Dunno. Haven't seen any explanation thus far which has made much sense.
Though some time back when I started tinkering with solid state single-ended amplifers which often use a large electrolytic output coupling cap or caps to block the DC offset of the amp, I saw that bi-wiring could afford the opportunity to bypass the main output coupling cap(s) and drive the high-pass section directly from the amp's output.
That's about the only scenario that's made any sense to me at least from a technical perspective.
