Or, to include my own bias in the question, â€œWhy does bi-wiring work?â€
Some speaker manufacturers provide for bi-wiring, some do not, and a few of those that donâ€™t seem pretty dismissive of the whole idea.
It sure works for me! When I built my current speakers (details below) I made them bi-wirable so I could mess around with it. I expected to make extensive listening tests, but the difference was so obvious that I decided in five minutes that bi-wiring was better, in my case at least. Bi-wired, the speakers were much more dynamic, and the sound opened up spatially in the most remarkable way. It was not close.
So I wonder two things: 1. Why does bi-wiring work? Iâ€™ve read several explanations, the most plausible of which (to me) is that it lets less of the wooferâ€™s back-EMF into the tweeter.
And 2. Why do some speaker manufacturers downplay the efficacy of bi-wiring? Is it because bi-wirable speakers are by definition bi-ampable, too, and theyâ€™d rather not give their customers the ability (in a horizontal bi-amp setup) to change the tonal balance of their products? Or could some kinds of speakers sound worse when bi-wired?
[FYI my home-brew speakers are smallish, 2-way, sealed-box units with 6â€ paper-cone Vifa woofers and cloth-dome Scan-Speak tweeters. Crossover is 1st-order at 2.8 kHz, and there is a Zobel network on the woofs. Bass alignment is somewhat over-damped, Q = ca. 0.63.
The wires are 24â€™ runs of Sound King 10G. Level-match was checked with a volt-meter. The wire was not doubled-up for single wire listening, I just discoed the tweeter wires and strapped the terminals together.]
