Why Bi-wiring Makes No Sense.

[mtrycrafts]

[QUOTE=Haoleb]
The higher frequencies would see a high impedance on the cable going to the bass section of a bi-wired speaker. The opposite goes for the bass. Just like how robert harley had explained it in the book. Therefore, Just like he had also explained the seperate frequencies would take two seperate paths.

Not totally correct.
The voltage of that higher frequency is at the input terminal of the low section and vice verse at the high drivers.
AND, the slope of the crossover to each segment dictates how much current actually will be delivered to each driver. They are not brick filters, hence, you will get a pretty good amount of out of band currents in each section. It is that simple.


And ALSO like he had explained because the bass drivers would require more current than the other drivers the cable powering them would have a larger magnetic field around it which in theory could affect the high frequency cable due to induction.

Would he like to prove that this affects in any way the high frequency current? I'd like to see the numbers, thanks.

The same principle applies to not running your signal cables parallel to high voltage cables.

That 60Hz is somewhat a different issue, isn't it? that 60Hz is what would be coupled onto the signal cables, not other frequency. And, as far as speaker cables go, the high drivers slope would also control how much 60Hz would in fact be in the driver, period.



Perhaps before questioning and rolling your eyes at someone's quotes you should try to understand the science behind them.

Applies to you as well.

The problem with that 'science' is that each driver will 'see' the entire frequency range and its xover will then filter out what it can't deal with - the same exact thing that happens when you don't bi-wire.

Bi-wiring is absolutely pointless unless you use an active xover to filter out the frequencies BEFORE they get to the driver.

Bi Wire..... rhymes with....
snake oil

Stick to audio, not poetry

There are useful things in that book, but then there is a lot of phooey in that book as well.

There may be; most likely there are. BUT, one needs to know which is snake oil and what is useful. If one knows, why buy and read the book?

[mtrycrafts]

He's opened my eyes to a few things and for that I say thanks Mtry.

That's what its all about, greater knowledge with open eyes

Got the book for free, plus I got a hug. I came out on top of the game.

Im not talking about the resistance of the cable.

OK, but what performance advantage does Bi-wiring offer? If you use one cable run straight to the speaker it would do exactly the same thing at the terminals of the speaker as it would if you bi-wired the speakers. The only difference it would make, if what you say is correct, is at which stage down the line it occurs. Unless I am missing something, but I have tried both ways and hear no advantages of bi-wiring.

I think this attachment really says it all.

Picture's worth a thousand words, thank you Jonnythan. You have illustrated my point about as clearly as it could ever be.

The voltage might be there but the current isint. Thats the whole point.

I dont say that Bi-wiring makes a difference. The only reason I joined in on this thread was to say that some of the points that are made in the book are completely valid. Thats all! Nothing more!
