Bi-wiring will only theoretically be a benefit when drivers distort and linearity is no longer maintained (non-linear).With sufficient voltage a driver can deviate from ideal linearity so the current in that connection between the low output impedance of the amplifier and the woofer (in this case), will carry harmonic distortion components which can create intermodulation products. In a simple non-bi-wire situation, the tweeter driver terminals will see these distortion components through the speakers (low to zero) impedance straps (when a single non bi-wire set of cables is used).The theoretical advantage is now valid if you assume a set of bi-wire speaker cables has some finite impedance (obviously, the longer the cables, the more pronounced the effects will be). When bi-wire cables are used rather than single wires with straps, the distortion components (caused by the woofer driver) will have a lower impedance path to the amplifiers low output impedance sink, rather than travel back and down the tweeters speaker cable.Yes, it's a small advantage and you could argue that the tweeters crossover would help to reduce the problem, but I suppose you could argue that the harmonic and intermodulation products will be at a higher frequency and may pass through to the tweeter driver.The entire advantage is gained by asking this question. From the perspective of the woofer driver terminals, which is the lower impedance path to the tweeters driver terminals? Is it a set of straps in a non bi-wire situation, or is it the route of a set of bi-wire cables that has a theoretical ideal voltage source (amplifiers low output impedance) in the path?.......... The answer is the bi-wire configuration.Unfortunately, the benefit would be about the same result as attempting to slow your car down by putting your hand out the window? I doubt anyone could hear the benefits of bi-wiring, but the theory is there to prove it works.brucek
I did. In my case the answer was "no".Nap.
The distortion path still exist whether it's bi-wired, tri-wired or not.. it's just a matter of it taking a few more feet to hit low/high pass filters. Only way to fully disconnect the paths is to bi-amp.

but if I got it, to paraphrase - the improvement in bass I heard in the biwired speaker may be more the result of the removal of the strap and replacing 16ga. wire with 12 ga. vs. the 'theoretical' chance of improved sound that biwiring might provide.
What do you do for work?
The lower impedance path for distortion components would be to ground through the output transistors of the amplifier.
... hit the second speaker almost identical to the jumper.
Wired up one speaker with Supra Rondo 4x4.0, a nice cable with 4 leads of 11 ga.The biwired speaker sounds so much more 'alive' than the speaker traditionally wired with 16 ga. Monoprice speaker wire and jumper cables.
I know that this topic has been discuss a million time,but i just want to know what are the benefits of Internal bi-wiring and True bi-wiring.My apology for bringing up this debatable topic again.
