IIRC I used 4x leads on the bottom while definitely using the 'alternative' 2x leads on the top. Ooh, la la

  But the amp sees the two Zeros in parallel, thus reducing the net impedance seen by the amp by half, assuming the impedances of the treble and bass components are equal. Whereas increasing the apparent impedance of the speaker is the main goal of using Zeros in the first place. I have to think about this, but I am guessing that the net impedance seen by the amp is not higher than what one achieves with one Zero. I would not argue with your real world results, however.

    I think he is saying 1 zero and using 2 sets of taps. The question remains however if this puts the treble and bass in series or parallel?

      Lew was wise to not doubt my real world results, bi-zeroing was definitely one of the most memorable audio epiphanies I've experienced, and I've had a few.
      
      I don't use any Zeros with my current loudspeakers.

      unless you deliberately create a series connection by reversing the leads for one driver vs the other. But if you can do that, you may not need a Zero at all.
