Though I agree with the premise about bi-wiring, the idea that nothing
exists that cannot be measured is dead wrong.

Humans didn't have the ability to measure the curve of the surface of the
Earth until the Arabs did it in the early dark ages. Does that mean the
world was flat until they figured out how to measure it???

We need to present a good logical argument to defend the fact that
bi-wiring
doesn't do anything.

Here is my attempt at the "good logical argument."

It's called the application of Kirchoff's laws.

Since the bi-wired speakers ultimately connect to the same set of output
terminals on the voltage source (amplifier/receiver/whatever) all of the
points on both pairs of conductors will be at the same electrical
potential at any one point in time.

Excluding the negligible resistance of the conductors (if you are using 300
feet of 28 gauge wire for your speakers, you've got bigger problems than
thinking that bi-wiring makes a difference) it doesn't matter if you use
one, two, or forty-eight pairs of wires between the same set of output
terminals and your speakers -- they'll all be coincidently connected and at
the exact same electrical potential and therefore make no difference.

Essentially, all bi-wiring is doing is moving the shunt-block from the back
of the speaker to the back of the amplifier. If this makes a difference in
the sound, there is a problem with one or more of your speaker wires.

If you want to make use of separate speaker input terminals, get a pair (or
six or forty-eight) amplifiers and drive each one with the output from an
electronic cross-over that is tuned to bandwidth-limit it's output to match
the effective range of the driver being excited, then -- as long as each
circuit shares no common output-to-input conductors -- you have created a
system that can isolate the reactive loads presented by each of the
individual drivers.

Opinion

Of course, with this approach you now you have cross-amplifier
volume-adjustment linearity and level-matching issues that may make the
final result less accurate than the single-source/single amplifier solution.

Do what sounds best, but don't expect physics to make an exception for a
bi-wired configuration just because somebody said it would make a
difference.
