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?

Biwiring makes a noticeable difference in my three sets of ATC speakers. I have done the experiment numerous times. I also found that I preferred the sound with the stamped stock jumpers rather than expensive jumpers that I have tried. Go figure!

I add that I have a modicum of electronic savvy!

i guess i should have made the AND font size 60…. and separate the bass wire 4” from the mid / high….…..

every now and then reading comprehension kicks in and somebody borrows those frequent flyer shotgun biwire Audioquest hyper litz Type 6 cables…. 


Biwiring is nonsense. It does nothing but might cause a phase/time issue.....BiAMPing is a huge improvement to many speakers with a good crossover BEFORE the amplifiers. That is truly what the four terminals should be referenced for.

Part of the cost/performance bi-wire "argument" is that the higher frequencies do not require as much gauge as the lower end.  Therefore, put less of the "good stuff" (i.e. better material) on the top end thus extracting the best sonics from those materials, and bulk up (add meat) to the bottom end with less expensive materials to get more gauge.  This optimizes the cable budget using the most cost effective materials where they'll yield the best sonic benefit(s).

How in God's name can a single amplifier put the highs on one wire and the lows on another? And if it could, would not different gauge wire cause all kinds of phase/timing issues......(I know at the frequencies of HiFi audio this really doesn't matter...)
