The answer is no. When you bi-wire the M60 you are still using the crossover in the speaker.

The only time you would want to bypass the speakers crossover circuitry is when you are (active) bi-amping. The active portion being the use of an external crossover and separate amplifier channels powering each individual driver or section (bass, midrange, treble) of the loudspeaker.
