How does bi-wiring work?


To start, I do bi-wire my main speakers. However, I am somewhat confused about how bi-wiring works given that the speakers have internal crossovers and the signals received by them have the same full frequency range going to both sets of terminals.

I confess that I don't see any difference from single wiring in terms of the speaker's performance. What am I missing?

We need to recognize that the concept of bi-wiring came from speaker manufacturers, not cable manufacturers.  Some of the most brilliant, and respected minds used real science to reach their conclusions.  Based on my limited understanding, when a woofer is moving it creates back EMF, thus interfering with the upper frequencies.  I would suspect this phenomenon can be measured, and validated.  The concept of bi-wiring caught fire with the majority of "legit" speaker companies adopting it, and touting its sonic benefits.  This may be the case of "mass duplification" (lots of people being duped) or some of the best of the best talent in the industry saw and heard something real here.

It is not the function of cable companies to debunk manufacturer's marketing materials and methods.  If so, they'd rip them a new one for the crappy cables they use internally and their sonically degrading "high manufacturing/service efficiency" connection/termination methods.  So, offering up a product that embraces a (respected) manufacturer's credibility position is neither blind, nor unethical.  Just good business, based on a solid foundation.

Even if biwiring has audible benefits, it creates a whole load of unneeded complexity. It also means that the speaker cable budget has to be split across two sets of cables rather than using one better cable for the same budget and more than likely negating any audible benefits from bi-wiring with inferior cable.

The debate about the better single cable + jumpers vs the lesser twin cable bi-wire set…plays out often at GREAT non dogmatic music loving Audioquest dealers nationwide…..I’ve spent quality time at 2 with VERY similar systems ( not identical ) and obviously different rooms and have heard both arguments win…. One dealer carries AQ, Kimber and Nordost, the other AQ and Cardas. One great thing about a superb dealer / customer relationship is the loan of both sets…
