Why do you think Bi-Wiring improves the sound ?

I run an old pair of Acoustat 1100's which are bi-amped and bi-wired as the demands of the woofer modules and panels are quite different.  It did make a difference.

vair68robert.  So!  You disconnected the speaker posts, modified the crossover, added more speaker posts, yet you are convinced that the difference you think you hear is the bi-wiring.  Hmmm.

     Despite the fact that I have always thought bi-wiring is hokum, I am offering info from Vandersteen; however, the company does point out that the only advantage is from getting the magnetic field generated in the the woofer wires away from the mid/tweet wires, due to resistance differences. i.e. it can only work if you separate the wires from each other:   "The crossovers in Vandersteen bi-wirable speakers are engineered with completely separate high-pass and low-pass sections. The bass inputs pass low-frequencies to the woofers, but become more and more resistive at higher frequencies. The treble inputs pass high-frequencies to the midrange and tweeter, but become more and more resistive at low-frequencies. The output from the amplifier always takes the path of least resistance so deep bass frequencies go to the bass input (Low impedance at low-frequencies) rather than to the treble inputs (High impedance at low frequencies). For the same reason, treble frequencies go to the treble input (Low impedance at high-frequencies) rather than to the bass inputs (High impedance at high-frequencies). At the actual crossover frequency, the output from the amplifier would be divided equally between the two inputs as they would both have the same impedance at that frequency. Because of the different reflected impedances of the cables, the crossover between the woofer and midrange actually occurs at the wire ends where they connect to the amplifier."     Caveat Emptor.
  

For those of you who state that you use both sets of speakers posts, because the speaker was designed for bi-wiring:  NO IT WAS NOT!  It was desigined for bi-amping.  Bi-amping separates the current going to the woofers, and to the mid/tweeets.  Bi-ampig does not.  However, See my post from Vandersteen for resistive effects from woofer impedence.  i would like opinions on this, because it makes sense to me, despite my Hokum Meter.

Maybe getting higher quality jumpers rather than using the typically crappy factory ones would be a factor too.
