I have a question about the biwiring..

haggy · 12th April 2007, 01:59 PM

The biwiring of a speaker is for preventing the back EMF from woofer has effect on the tweeter.
I read it audio guide book.

But I don't know why back EMF has an effect on the tweeter.
I think the back EMF of woofer is same frequency with woofer.
And capacitor is connected in serial for a low cut filter.
By the way.... How can low frequency influence to the tweeter?

I confused -_-'''

Somebody help me....

Best regards, Haggy

Simple. The guide book is wrong. Your logic is correct.

That was maybe sponsored by a cable manufacturer?

There are indeed points that speak for biwiring. But the differences must be subtle IMO so I didn't try it by myself so far.

It would actually even be impossible to do with my setup: I am running fully active.

Sorry. You have lost me: if you are running fully active, you must be wiring separately to each driver already(?).

actively driven speakers are usually not what is called "biwired". The term refers usually to: split the passive xover that one amp drives the highpass, the other the lowpass branch of the xover.

Other biwiring refers to the fact that some folks run a dual set of wires to the speaker...

Many consider the Dynaudio Evidence Master the finest speaker ever made (take a look at the frequency response). Dynaudio speaker only have one set of binding posts. No bi-wiring is possible.

True story. Once I overheard somebody ask if the speakers could be bi-wired when shopping at some electronics warehouse-type chain. I'm sure the guy didn't know what bi-wiring was other than it's the thing to have.

If you replace "bi-wiring" with "bi-amping", then there is a benefit.

Here are a couple of helpful articles about it:

not if you biamp with a passive xover.
