The crossover consists of: - a 2nd order high pass (12 dB / octave) for the tweeter. - a 2nd order low pass (12 dB / octave) for the midrange woofer. - a 2nd order low-pass filter (12 dB / octave) for the woofer. The frequency response of the speaker is balanced. The decay spectrum is almost error-free. The non-linear distortions at medium volumes (90 dB, 1m) are below 0.4% above 300 Hz.
