Hi Grant,I don’t know the answer to this … but with d&B Q1 design, which is very similar to this, I have always been concerned about the different time arrival form the front and back of the speaker cone and reflections within that horn cavity as the frequency increases.Mike crosses his over at 585Hz … may be to avoid that second big dip at about 730HzAlso EAW KF364 is similar and they cross it at about 490Hz. Have a look at frequency response below. It looks similar but the two dips are at a higher frequency.
