What is biwiring?

[anders.a]

This biwiring is confusing stuff. What is he really talking about?

Is this really true or have I misunderstood something?

The only argument I can buy (and IMO it's a stretch ) is that a single cable can reduce the damping factor of an amp. Interaction between the sections of crossover are 'locked' behind this reduction in damping factor. Running a separate wire from each section to the amp will therefore reduce unwanted crossover interaction.

I use an amp with a low damping factor, I don't bother with bi-wiring instead choosing to do something that will make a real difference.

That's not very serious article. What are you particularly confused about?

I started to get lost about here:

“But we digress - back to the crossover. One of the problems with a standard crossover is that since one pair of cables carries the signal to and from the amp, bass signals can tend to swamp the more delicate treble stuff, especially in the return (or negative) connection back to the amp. “

and

“By separating the signal all the way back to amplifier's output stage, using two runs of cable or a purpose-made four conductor biwire cable, these effects can be greatly reduced. To do this, you need speakers designed for biwiring.
That means the crossover needs to be completely split, without the common negative found in standard design.”

And

“To all intents, a biwirable crossover is two separate circuits - one to filter the treble out of the signal for the bass driver, the other to prevent the bass from reaching the treble driver.”

Yes, these are most humouristic parts of article. Trust your own mind.

P.S. reread first paragraph you've quoted.It purely violates current Kirchhoff's law. You should have quit reading there.

biwiring: (verb) the act of selling an extra set of overpriced speaker cables to the naive consumer, usually resulting in a nice bonus for the salesman.

Biwiring really shud be spelled "buywiring". It is just another snake oil, faith based concept turned product designed to separate the gullible consumer from his cash.

"buywiring",

Good one Bob!

It's either that or single-pair binding posts Dynaudio doesn't know loudspeakers.

How about this guys. I've never felt the need to "buywire"..but I guess having a crossover next to your amplifier and then running a pair to your tweeter and then a pair to your woofer ( in the case of a 2 way) should have advantages?
