thanks

I can see there's a difference of opinion as to what's what & it all depends on who you learned it from.

My take on bi-wire is this:

Single bi-wire: Two terminations at the amp & four at the speaker per side. Two separate cables needed for a stereo hook-up.

Bi-wire or true bi-wire: Two terminations at the amp & two at the speaker. You need two runs per side for one speaker. Total of four separate cables for one stereo hook-up. With this configuration, you either have to stack at the amp end or have two sets of binding posts on the amp.

Shotgun bi-wire: This doubles the cable (wire) for each leg.

As for the differences, it really all depends on what you like. Out of all the possible configurations, the only one I didn't care for was a shotgun single bi-wire set-up. I now use a true bi-wire configuration, mostly because the binding posts on my VR4's are 3' apart.

If you decide to experiment just remember to trust your ears.
Shotgun biwiring utilizes four separate cables runs for each speaker. I used this configuration in two different speaker cable brands for a couple years. Now I have a new brand which utilizes standard internal biwiring so I only have a single fat cable for each speaker. That is, until it reaches the back of the speaker where there are still four separate connectors.
your question is a good question. there are many different ways to bi-wire a speaker. here is a quick explanationon of my opinion of bi-wire cables:

before i attempt to explain this, the main take away is a true biwire set up is at least 4 pairs of cables - utilizing 2 pair per side.

types of biwire:

single biwire- is when the cable that is seperated into 4 terminations at the speaker end and 2 at the amp end. depending on the original design this may not be optimal since the able was designed as a single +/- cable, now it is a +/- to a ++/-- ( ie you literally spilt the cable in half)you'll see alot of cardas cables this way.

true internal bi-wire or internal shotgun - imagaine if you had two pair of cables and all you did is connect the amp ends together so you have 2 spades vs. 4 spades and you put the 2 pairs of cable in one sheath so it looks like a single cable ( harmonic pro 9's are like this and can be used this way, they are 2 pair of pro 11's in one sheath)

it is two +/- cables sheathed in one housing(2 per speaker) so you have one + and one - at the amp end coming down to +/-,+/- at the speaker end. this is a true biwire can also be a called a "internal shotgun" since the speaker cable is doubled up or two pairs of cables.

shotgun or external bi-wire- same as above,imagaine if you had two pair of cables and all you did is connect the amp ends together so you have 2 spades vs. 4 spades and you DONT have the housing) this is a true biwire can also be a called a "external shotgun" since the speaker cable is doubled up and it is visable ( yea it looks cool because it is big)

DIFFERENT Types
there are different types of shotguns biwires- some manufactures ( like tara) use 1 cable per termination - so you have 2 positive wires coming coming to one at the amp end and 2 negative wire coming to one at the amp end PER SPEAKER ( so you now have 4 wires externally - 2 plus and 2 negative PER SPEAKER) vs. 2 ( you have two plus combined and 2 minuses combined( - all they did was seperate the positive from the negative..really not that big of deal - it does look cool though). I am selling a pait of tara master gen 1's if you want to see a picture, it is here on audiogon)

i hope that helps out, you should listen to your speakers with a tue bi wired cable. most speakers designed that way do sound thier best when they are bi-wired.

the drawback to the whole true bi-wiring gig is you are paying for a extra set of cables.
