According to Peter Aczel or "The Audio Critic", biwiring is one of the 10 biggest lies in audio.
Quote:"The Biwiring Lie
Even fairly sophisticated audiophiles
fall for this hocus-pocus. What’s more,
loudspeaker manufacturers participate
in the sham when they tell you that
those two pairs of terminals on the
back of the speaker are for biwiring as
well as biamping. Some of the most
highly respected names in loudspeakers
are guilty of this hypocritical genuflection
to the tweako sacraments—
they are in effect surrendering to the
“realities” of the market.
The truth is that biamping makes
sense in certain cases, even with a passive
crossover, but biwiring is pure voodoo.
If you move one pair of speaker wires to
the same terminals where the other pair
is connected, absolutely nothing changes
electrically. The law of physics that says
so is called the superposition principle.
In terms of electronics, the superposition
theorem states that any number of voltages
applied simultaneously to a linear
network will result in a current which is
the exact sum of the currents that would
result if the voltages were applied individually.
The audio salesman or ’phile
who can prove the contrary will be an
instant candidate for some truly major
scientific prizes and academic honors. At
the same time it is only fair to point out
that biwiring does no harm. It just
doesn’t do anything. Like magnets in
your shoes."
