. . . may be a "design feature" rather than an error. I recall some implication in the article (I'll have to read it again) that it is intended to reduce vocal sibilance. JA determined it was NOT a phase cancellation (it was still there when he flipped the polarity of the tweeter), and the other Audiovector models he measured did not have it.
The audible effect is easy to simulate, if you have some reasonably flat-measuring speakers and an EQ. Just cut an 8dB notch, about half an octave wide, centered at 3kHz, and listen. I hear a discontinuity in the treble, as if the upper harmonics are not properly attached to their fundamentals. But it does reduce sibilance on "hot" recorded vocals.
