I'm a tad confused (as always), you are running full frequency info to both woofer and tweeter/mid bypassing the crossover?
The wiring setup that the original poster describes is typical of loudspeakers designed for bi-wiring, and still keeps the passive crossover in place. Both pairs of loudspeaker binding posts see signal voltage of the full frequency range, but only draw significant current from the amplifier through their respective frequency ranges.
