He is the inventor of the Zero and has thought a lot about the various ways in which they can be used. I think I asked him this very question once upon a time and was advised not to do it, but the reasoning escapes me. However, one possibility is that the desired benefit of raising the impedance in the bass only, without altering the impedance of the rest of the speaker, probably does not happen, because as Duke noted everything is in parallel. The only way to make it do what you want is to bi- or tri-amplify the speaker and use the Zero after the bass amplifier only. OTOH, I would very strongly suggest that you just use a Zero between your amp and your whole speaker; it's not going to hurt the midrange and treble reproduction a bit, unless you use a very high multiplier of the impedance. Stick with 4X or lower multiplication and you will like it. But first make certain that the reason you are getting a "softening" of the bass is due to an impedance dip at those frequencies and not some other factor.
