The recombined amplitude response of the speaker: you can see whether the combination of the drivers is constructive,
and you can observe the effects of level/delay/polarity modification on the combined amplitude of the speaker. Two
curves are displayed, one showing the global power of the speaker (including the room), and one showing the amplitude
of the direct front and early reflections. Comparing both curves will indicate you whether the crossover conserves the
directivity of the speaker: the more alike the two curves look, the more directive the speaker is towards the listening spot.
NOTE:
 The levels, delays and polarities set previously are ignored during the calibration. In other
words, adjusting these parameters before launching the calibration will have no effect on the
result.

Under some circumstances, the automatic crossover algorithm may suggest inverted
polarities for a driver from one speaker to another. This can be explained by various factors:
o
The physical polarity of one speaker is, indeed, inverted (from a cabling issue, as an
example). In this case, the correction suggested by the Optimizer should be applied to
improve audio quality
o
Two adjacent drivers (for instance Mid and High) are phase-shifted by an amount of
about 90°. In this case, the Optimizer provides more uncertain results, as it gets harder to
see whether the drivers are in or out of phase. If you are not comfortable with the results
provided by the Optimizer, you can correct them manually afterwards (via the button
“Invert polarity”).
