Bi-Wiring

I know that this topic has been discuss a million time,but i just want to know what are the benefits of Internal bi-wiring and True bi-wiring.My apology for bringing up this debatable topic again.

Do a search and you will find hundreds of discussions about this topic.I think most folks are pretty tired of talking about it!!

Deftone dont feel bad............My Kef 207-2`s are *Tri Wire* lol......

I beleive alot depends on crossover design . There are several world class speakers that use single wire such as Folcal and Sonus Faber that makes the Cremona!... JBLs of my vintinge do well very well with two terninals .

These are Bi Wired

With These !!!

Isn't that bi-amping instead of bi-wiring?

A good article showing how bi-wiring works: http://www.st-andrews.ac.uk/~www_pa/Scots_Guide/audio/biwire/Page1.html

vegasdave incorrect

Speakers are Bi-wired ... as you see in the pic...

And connected with These .

My set is called Vertical Bi Amp Set up

Take a look here.

Left and right Channel are Bi Wired & Split

So I guess you know what I mean Sound Stage is Split left and Right

I'm confused. If you are vertical bi-amping, then how are you bi-wiring. Bi-wiring is running 2 sets of wires off of one amplifier terminal. While you can mix bi-amping and bi-wiring this would require 3 speaker conenctions.

I do both. My VMPS RM30s run a plate amp to the woofers and a SET amp to the mids/tweet. There are 2 sets of speaker wires coming from the SET amp, one for the mids and one for the tweeter.

How many Sets of Wires do you See ?
The Speakers are Bi-Wired .....

The 4B SST2 are dual mono design : Means that I have 2 sets of speaker wires going to each 4Bsst2

and my Note Below on Vertial Bi-amplification

Vertical Bi-amplification dedicates one amplifier to each speaker. This
configuration provides complete channel separation, which optimizes your
system’s imaging ability.

Any questions let me know

You're bi-amping, and as a default, you're bi-wiring. I know this.

In all the conversation/threads I've read about bi-wiring, I've yet to see what the effect is on the amp, just what it may do to the speaker crossover.

So, has anyone documented the effect of biwiring on a Bryston amp?

What about ShotGun?In fact i was already looking at this two cables,Acoustic Zen and another one from PAD.The only disadvantage is i am no way able to audition this 2 cables.So,it is right to say that i am more incline to the reviews that i`ve read about this cables,than listening to the real thing.Any comment on this 2 cables?

The amp would see a different load impedance....

Got any specifics there Nappy?

The reason I ask is a friend brought by a set of MIT bi-wires, but they were to short for 1 speaker, so set up 1 bi-wired, left other with Monoprice 16ga. and the speaker's supplied jumper.

Bi-wired sounded fuller with better bass.

So, is it;

1) The act of bi-wiring the xover,
2) Change to the output of the amp, (a 30 yr old 4B),
3) The fact the jumper wire, maybe 16ga or 14ga has been replaced by the 12ga wire of the MIT product
4) The fact the 16ga wire completely removed from the speaker that was bi-wired.

A Bryston 4B feeding Onyx Reference 3 speakers with Skiing Ninja Master xovers.

Just the basic electrical circuits theory....

I don't feel like drawing now, but you can do it from my description:

Let's say you have cable impedances Zc1 and Zc2 (two different cables). And Zt, Zb impedances of tweeter and bass driver circuits.

In single wire, the amp sees Zc1 in series with a group formed by Zt and Zb connected in parallel.

In bi-wire, the amp sees a parallel group of two series subgroups, one is Zc1 + Zt, the other is Zc2 + Zb.

The impedances seen by the amp would be different except some degenerated cases (0 cable impedance, or stuff like that).
