What is "biwiring"?


HI. Quick question-what is biwiring for speakers with 2 sets of terminals? I see that some cable companies are using a single strand of wire, terminated twice on the speaker end. Others have 2 sets of wire run together, 1 set each has connectors on the speaker end, but only 1 set total of connectors on the amp end. Another method is using 2 sets of cables-one set having spades on the amp end, one set bananas on the amp, so that both can be connected simultaneously to the same terminal.

Which is considered "biwiring"? Which sounds best?

All good advice, however...

It is a definite advantage to split the signal at the amp end and it is a must to use the same brand cable. Sounds like AQ are talking out of the wrong hole here. For the same reason that you must use the same length you must use the same cable. There is no point matching lengths if the basic electrical properties are all different. The signal getting to the various bits of the crossover must be in-phase and this simply will not happen if the electrons take different routes.

Is biwiring beneficial?
Opinion is divided mainly because the effect can be so different. If you have a relatively resistive wire going to insensitive speakers then the best thing to do would be to give the bass driver as much help as it can get, and go for a single-wire. No point in cossetting the treble if the bass driver is having problems getting its amps. Sensitive speakers don't experience the downside of biwiring nearly as much so its best to get the benefits of keeping the signals apart and go for the biwire option. Shotgunning gives the best of both worlds but then a single-wire configuration of cable twice as expensive becomes an option (an unfortunately good one for many of us).

Good information, Nullgeodesic. Thank you.

Oh my; we're talking about the AUDIBLE differences of billionths of billionths of a second now? '...basic electrical properties are all different'? Hardly.

Audioquest has perhaps hundreds of years of combined experience on its staff of people who care very much about sound quality and how to optimize it thru cable. YOU suddenly are smarter than all of them? I doubt it.
