Understanding BiWiring

Submitted by on April 7, 2010 – 7:31 amOne Comment

Many of today’s speakers can be “BiWired”, meaning the speaker has separate inputs for the woofer and separate inputs for the higher frequencies.for example, nearly every speaker we offer from Bowers & Wilkins has two sets of speaker terminals on the back, two positive & two negative.  BiWiring is a way to get higher performance out of your speakers, therefore giving you a better return on your audio investment.

When using a single full-range speaker cable (not biwiring), the large amounts of bass energy carried withing the single cable has an adverse effect on the higher frequencies.  In a BiWire setup, the cable feeding the higher frequencies no longer handles the large magnetic fields caused by the high current needed to produce bass.  BiWiring does not affect the bass fundamentals, but allows the treble signal to now travel a less disturbed path.  It’s a bit like the difference between swimming through waves versus through smooth water.  Bass frequencies will sound better because bass definition is actually located in the midrange and higher frequencies.

It is always worthwhile to take advantage of the benefits of BiWiring when the speaker manufacturer has gone to the extra expense of providing this capability.  The performance benefits of reducing distortion in this way are substantial!

Audioquest, our go to cable provider has a significant range of BiWire speaker cables available.  Come visit our showroom to hear the advantages of BiWiring with your own ears.
