The "Fig 5" circuit is a 12dB/octave Butterworth high-pass with a corner of 5300Hz. It therefor attenuates the energy going to the tweeter, 12dB/octave below 5300Hz. So it gives some pretty good tweeter protection.
In conjunction with the tweeter's falling response, then net total acoustic response is roughly equivalent to a highpass at 3000Hz, according to the manufacturer specs being quoted. But that is NOT what the electrical filter is doing, that's just the total effect of filter plus tweeter response.
