Biwire Cables for Vandersteen 2CE Signatures

Side question. I see the terms true and external bi-wire and not sure what they really mean. If the amplifier has only one pair of output port per channel the wires pair(s), inside the sheath or outside, need to be twisted and single terminated on that end. Is there any other way?

an internal biwire normally has 4 wires per channel in a common sheath - very little physical space between HF and LF conductors
principal theory being the large current demands of LF and the field that generates modulates the HF signal = degredation

a shotgun typically has common termination at amp ends but splits the HF and LF runs into different cables that importantly can then be spaced 3-4” apart

you can kind of get same effect w two sets of cables, i personally dislike stacking spades and trying to get a gas tight connection and not get shorts at the amp end, hence my preference for shotgun

hope that helps

Thanks for the explanation. I missed the tidbit about the (negative) interaction between the LF and HF pairs if they live within the same sheath. I expected good quality cables have adequate insulation to avoid that sort of "cross-talk". That said, one could extend that concern to having negative and positive cables inside a common sheath as being a poor practice. I have my 2Ci model bi-wired as well but my amplifier has two sets of output posts and using two separate sets of cables so I suppose mine is considered ""true" bi-wire.

@kalali  You are wiring up your 2Cis the way Richard V. intended.  I haven't run across a designer who is more adamant about this way of wiring up speakers nor have I ever read a review of Vandersteen speakers where the reviewer didn't agree that the speakers sounded more coherent with true biwiring.  Whatever RV is doing with his crossovers, it is consistent in benefitting from biwiring.

Some good comments above.
I'm having nice results using bi-wire Anticables between my Krell and my 2Cs.
Very happy with the sound.
